2010-02-04 15:47:10 +00:00
cmake version 2.8.0
------------------------------------------------------------------------------
Name
cmake-gui - CMake GUI.
------------------------------------------------------------------------------
Usage
cmake-gui [options]
cmake-gui [options] <path-to-source>
cmake-gui [options] <path-to-existing-build>
------------------------------------------------------------------------------
Description
The "cmake-gui" executable is the CMake GUI. Project configuration settings
may be specified interactively. Brief instructions are provided at the
bottom of the window when the program is running.
CMake is a cross-platform build system generator. Projects specify their
build process with platform-independent CMake listfiles included in each
directory of a source tree with the name CMakeLists.txt. Users build a
project by using CMake to generate a build system for a native tool on their
platform.
------------------------------------------------------------------------------
Options
--copyright [file]
Print the CMake copyright and exit.
If a file is specified, the copyright is written into it.
--help
Print usage information and exit.
Usage describes the basic command line interface and its options.
--help-full [file]
Print full help and exit.
Full help displays most of the documentation provided by the UNIX man
page. It is provided for use on non-UNIX platforms, but is also
convenient if the man page is not installed. If a file is specified,
the help is written into it.
--help-html [file]
Print full help in HTML format.
This option is used by CMake authors to help produce web pages. If a
file is specified, the help is written into it.
--help-man [file]
Print full help as a UNIX man page and exit.
This option is used by the cmake build to generate the UNIX man page.
If a file is specified, the help is written into it.
--version [file]
Show program name/version banner and exit.
If a file is specified, the version is written into it.
------------------------------------------------------------------------------
Generators
The following generators are available on this platform:
Borland Makefiles

Commands
add_custom_command
Add a custom build rule to the generated build system.
There are two main signatures for add_custom_command The first
signature is for adding a custom command to produce an output.
add_custom_command(OUTPUT output1 [output2 ...]
COMMAND command1 [ARGS] [args1...]
[COMMAND command2 [ARGS] [args2...] ...]
[MAIN_DEPENDENCY depend]
[DEPENDS [depends...]]
[IMPLICIT_DEPENDS <lang1> depend1 ...]
[WORKING_DIRECTORY dir]
[COMMENT comment] [VERBATIM] [APPEND])
This defines a command to generate specified OUTPUT file(s). A target
created in the same directory (CMakeLists.txt file) that specifies any
output of the custom command as a source file is given a rule to
generate the file using the command at build time. If an output name
is a relative path it will be interpreted relative to the build tree
directory corresponding to the current source directory. Note that
MAIN_DEPENDENCY is completely optional and is used as a suggestion to
visual studio about where to hang the custom command. In makefile
terms this creates a new target in the following form:
OUTPUT: MAIN_DEPENDENCY DEPENDS
COMMAND
If more than one command is specified they will be executed in order.
The optional ARGS argument is for backward compatibility and will be
ignored.
The second signature adds a custom command to a target such as a
library or executable. This is useful for performing an operation
before or after building the target. The command becomes part of the
target and will only execute when the target itself is built. If the
target is already built, the command will not execute.
add_custom_command(TARGET target
PRE_BUILD | PRE_LINK | POST_BUILD
COMMAND command1 [ARGS] [args1...]
[COMMAND command2 [ARGS] [args2...] ...]
[WORKING_DIRECTORY dir]
[COMMENT comment] [VERBATIM])
This defines a new command that will be associated with building the
specified target. When the command will happen is determined by which
of the following is specified:
PRE_BUILD - run before all other dependencies
PRE_LINK - run after other dependencies
POST_BUILD - run after the target has been built
Note that the PRE_BUILD option is only supported on Visual Studio 7 or
later. For all other generators PRE_BUILD will be treated as
PRE_LINK.
If WORKING_DIRECTORY is specified the command will be executed in the
directory given. If COMMENT is set, the value will be displayed as a
message before the commands are executed at build time. If APPEND is
specified the COMMAND and DEPENDS option values are appended to the
custom command for the first output specified. There must have
already been a previous call to this command with the same output.
The COMMENT, WORKING_DIRECTORY, and MAIN_DEPENDENCY options are
currently ignored when APPEND is given, but may be used in the future.
If VERBATIM is given then all arguments to the commands will be
escaped properly for the build tool so that the invoked command
receives each argument unchanged. Note that one level of escapes is
still used by the CMake language processor before add_custom_command
even sees the arguments. Use of VERBATIM is recommended as it enables
correct behavior. When VERBATIM is not given the behavior is platform
specific because there is no protection of tool-specific special
characters.
If the output of the custom command is not actually created as a file
on disk it should be marked as SYMBOLIC with
SET_SOURCE_FILES_PROPERTIES.
The IMPLICIT_DEPENDS option requests scanning of implicit dependencies
of an input file. The language given specifies the programming
language whose corresponding dependency scanner should be used.
Currently only C and CXX language scanners are supported.
Dependencies discovered from the scanning are added to those of the
custom command at build time. Note that the IMPLICIT_DEPENDS option
is currently supported only for Makefile generators and will be
ignored by other generators.
If COMMAND specifies an executable target (created by ADD_EXECUTABLE)
it will automatically be replaced by the location of the executable
created at build time. Additionally a target-level dependency will be
added so that the executable target will be built before any target
using this custom command. However this does NOT add a file-level
dependency that would cause the custom command to re-run whenever the
executable is recompiled.
The DEPENDS option specifies files on which the command depends. If
any dependency is an OUTPUT of another custom command in the same
directory (CMakeLists.txt file) CMake automatically brings the other
custom command into the target in which this command is built. If
DEPENDS specifies any target (created by an ADD_* command) a
target-level dependency is created to make sure the target is built
before any target using this custom command. Additionally, if the
target is an executable or library a file-level dependency is created
to cause the custom command to re-run whenever the target is
recompiled.
add_custom_target
Add a target with no output so it will always be built.
add_custom_target(Name [ALL] [command1 [args1...]]
[COMMAND command2 [args2...] ...]
[DEPENDS depend depend depend ... ]
[WORKING_DIRECTORY dir]
[COMMENT comment] [VERBATIM]
[SOURCES src1 [src2...]])
Adds a target with the given name that executes the given commands.
The target has no output file and is ALWAYS CONSIDERED OUT OF DATE
even if the commands try to create a file with the name of the target.
Use ADD_CUSTOM_COMMAND to generate a file with dependencies. By
default nothing depends on the custom target. Use ADD_DEPENDENCIES to
add dependencies to or from other targets. If the ALL option is
specified it indicates that this target should be added to the default
build target so that it will be run every time (the command cannot be
called ALL). The command and arguments are optional and if not
specified an empty target will be created. If WORKING_DIRECTORY is
set, then the command will be run in that directory. If COMMENT is
set, the value will be displayed as a message before the commands are
executed at build time. Dependencies listed with the DEPENDS argument
may reference files and outputs of custom commands created with
add_custom_command() in the same directory (CMakeLists.txt file).
If VERBATIM is given then all arguments to the commands will be
escaped properly for the build tool so that the invoked command
receives each argument unchanged. Note that one level of escapes is
still used by the CMake language processor before add_custom_target
even sees the arguments. Use of VERBATIM is recommended as it enables
correct behavior. When VERBATIM is not given the behavior is platform
specific because there is no protection of tool-specific special
characters.
The SOURCES option specifies additional source files to be included in
the custom target. Specified source files will be added to IDE
project files for convenience in editing even if they have not build
rules.
add_definitions
Adds -D define flags to the compilation of source files.
add_definitions(-DFOO -DBAR ...)
Adds flags to the compiler command line for sources in the current
directory and below. This command can be used to add any flags, but
it was originally intended to add preprocessor definitions. Flags
beginning in -D or /D that look like preprocessor definitions are
automatically added to the COMPILE_DEFINITIONS property for the
current directory. Definitions with non-trival values may be left in
the set of flags instead of being converted for reasons of backwards
compatibility. See documentation of the directory, target, and source
file COMPILE_DEFINITIONS properties for details on adding preprocessor
definitions to specific scopes and configurations.
add_dependencies
Add a dependency between top-level targets.
add_dependencies(target-name depend-target1
depend-target2 ...)
Make a top-level target depend on other top-level targets. A
top-level target is one created by ADD_EXECUTABLE, ADD_LIBRARY, or
ADD_CUSTOM_TARGET. Adding dependencies with this command can be used
to make sure one target is built before another target. See the
DEPENDS option of ADD_CUSTOM_TARGET and ADD_CUSTOM_COMMAND for adding
file-level dependencies in custom rules. See the OBJECT_DEPENDS
option in SET_SOURCE_FILES_PROPERTIES to add file-level dependencies
to object files.
add_executable
Add an executable to the project using the specified source files.
add_executable(<name> [WIN32] [MACOSX_BUNDLE]
[EXCLUDE_FROM_ALL]
source1 source2 ... sourceN)
Adds an executable target called <name> to be built from the source
files listed in the command invocation. The <name> corresponds to the
logical target name and must be globally unique within a project. The
actual file name of the executable built is constructed based on
conventions of the native platform (such as <name>.exe or just
<name>).
By default the executable file will be created in the build tree
directory corresponding to the source tree directory in which the
command was invoked. See documentation of the
RUNTIME_OUTPUT_DIRECTORY target property to change this location. See
documentation of the OUTPUT_NAME target property to change the <name>
part of the final file name.
If WIN32 is given the property WIN32_EXECUTABLE will be set on the
target created. See documentation of that target property for
details.
If MACOSX_BUNDLE is given the corresponding property will be set on
the created target. See documentation of the MACOSX_BUNDLE target
property for details.
If EXCLUDE_FROM_ALL is given the corresponding property will be set on
the created target. See documentation of the EXCLUDE_FROM_ALL target
property for details.
The add_executable command can also create IMPORTED executable targets
using this signature:
add_executable(<name> IMPORTED)
An IMPORTED executable target references an executable file located
outside the project. No rules are generated to build it. The target
name has scope in the directory in which it is created and below. It
may be referenced like any target built within the project. IMPORTED
executables are useful for convenient reference from commands like
add_custom_command. Details about the imported executable are
specified by setting properties whose names begin in "IMPORTED_". The
most important such property is IMPORTED_LOCATION (and its
per-configuration version IMPORTED_LOCATION_<CONFIG>) which specifies
the location of the main executable file on disk. See documentation
of the IMPORTED_* properties for more information.
add_library
Add a library to the project using the specified source files.
add_library(<name> [STATIC | SHARED | MODULE]
[EXCLUDE_FROM_ALL]
source1 source2 ... sourceN)
Adds a library target called <name> to be built from the source files
listed in the command invocation. The <name> corresponds to the
logical target name and must be globally unique within a project. The
actual file name of the library built is constructed based on
conventions of the native platform (such as lib<name>.a or
<name>.lib).
STATIC, SHARED, or MODULE may be given to specify the type of library
to be created. STATIC libraries are archives of object files for use
when linking other targets. SHARED libraries are linked dynamically
and loaded at runtime. MODULE libraries are plugins that are not
linked into other targets but may be loaded dynamically at runtime
using dlopen-like functionality. If no type is given explicitly the
type is STATIC or SHARED based on whether the current value of the
variable BUILD_SHARED_LIBS is true.
By default the library file will be created in the build tree
directory corresponding to the source tree directory in which the
command was invoked. See documentation of the
ARCHIVE_OUTPUT_DIRECTORY, LIBRARY_OUTPUT_DIRECTORY, and
RUNTIME_OUTPUT_DIRECTORY target properties to change this location.
See documentation of the OUTPUT_NAME target property to change the
<name> part of the final file name.
If EXCLUDE_FROM_ALL is given the corresponding property will be set on
the created target. See documentation of the EXCLUDE_FROM_ALL target
property for details.
The add_library command can also create IMPORTED library targets using
this signature:
add_library(<name> <SHARED|STATIC|MODULE|UNKNOWN> IMPORTED)
An IMPORTED library target references a library file located outside
the project. No rules are generated to build it. The target name has
scope in the directory in which it is created and below. It may be
referenced like any target built within the project. IMPORTED
libraries are useful for convenient reference from commands like
target_link_libraries. Details about the imported library are
specified by setting properties whose names begin in "IMPORTED_". The
most important such property is IMPORTED_LOCATION (and its
per-configuration version IMPORTED_LOCATION_<CONFIG>) which specifies
the location of the main library file on disk. See documentation of
the IMPORTED_* properties for more information.
add_subdirectory
Add a subdirectory to the build.
add_subdirectory(source_dir [binary_dir]
[EXCLUDE_FROM_ALL])
Add a subdirectory to the build. The source_dir specifies the
directory in which the source CmakeLists.txt and code files are
located. If it is a relative path it will be evaluated with respect
to the current directory (the typical usage), but it may also be an
absolute path. The binary_dir specifies the directory in which to
place the output files. If it is a relative path it will be evaluated
with respect to the current output directory, but it may also be an
absolute path. If binary_dir is not specified, the value of
source_dir, before expanding any relative path, will be used (the
typical usage). The CMakeLists.txt file in the specified source
directory will be processed immediately by CMake before processing in
the current input file continues beyond this command.
If the EXCLUDE_FROM_ALL argument is provided then targets in the
subdirectory will not be included in the ALL target of the parent
directory by default, and will be excluded from IDE project files.
Users must explicitly build targets in the subdirectory. This is
meant for use when the subdirectory contains a separate part of the
project that is useful but not necessary, such as a set of examples.
Typically the subdirectory should contain its own project() command
invocation so that a full build system will be generated in the
subdirectory (such as a VS IDE solution file). Note that inter-target
dependencies supercede this exclusion. If a target built by the
parent project depends on a target in the subdirectory, the dependee
target will be included in the parent project build system to satisfy
the dependency.
add_test
Add a test to the project with the specified arguments.
add_test(testname Exename arg1 arg2 ...)
If the ENABLE_TESTING command has been run, this command adds a test
target to the current directory. If ENABLE_TESTING has not been run,
this command does nothing. The tests are run by the testing subsystem
by executing Exename with the specified arguments. Exename can be
either an executable built by this project or an arbitrary executable
on the system (like tclsh). The test will be run with the current
working directory set to the CMakeList.txt files corresponding
directory in the binary tree.
add_test(NAME <name> [CONFIGURATIONS [Debug|Release|...]]
COMMAND <command> [arg1 [arg2 ...]])
If COMMAND specifies an executable target (created by add_executable)
it will automatically be replaced by the location of the executable
created at build time. If a CONFIGURATIONS option is given then the
test will be executed only when testing under one of the named
configurations.
Arguments after COMMAND may use "generator expressions" with the
syntax "$<...>". These expressions are evaluted during build system
generation and produce information specific to each generated build
configuration. Valid expressions are:
$<CONFIGURATION> = configuration name
$<TARGET_FILE:tgt> = main file (.exe, .so.1.2, .a)
$<TARGET_LINKER_FILE:tgt> = file used to link (.a, .lib, .so)
$<TARGET_SONAME_FILE:tgt> = file with soname (.so.3)
where "tgt" is the name of a target. Target file expressions produce
a full path, but _DIR and _NAME versions can produce the directory and
file name components:
$<TARGET_FILE_DIR:tgt>/$<TARGET_FILE_NAME:tgt>
$<TARGET_LINKER_FILE_DIR:tgt>/$<TARGET_LINKER_FILE_NAME:tgt>
$<TARGET_SONAME_FILE_DIR:tgt>/$<TARGET_SONAME_FILE_NAME:tgt>
Example usage:
add_test(NAME mytest
COMMAND testDriver --config $<CONFIGURATION>
--exe $<TARGET_FILE:myexe>)
This creates a test "mytest" whose command runs a testDriver tool
passing the configuration name and the full path to the executable
file produced by target "myexe".
aux_source_directory
Find all source files in a directory.
aux_source_directory(<dir> <variable>)
Collects the names of all the source files in the specified directory
and stores the list in the <variable> provided. This command is
intended to be used by projects that use explicit template
instantiation. Template instantiation files can be stored in a
"Templates" subdirectory and collected automatically using this
command to avoid manually listing all instantiations.
It is tempting to use this command to avoid writing the list of source
files for a library or executable target. While this seems to work,
there is no way for CMake to generate a build system that knows when a
new source file has been added. Normally the generated build system
knows when it needs to rerun CMake because the CMakeLists.txt file is
modified to add a new source. When the source is just added to the
directory without modifying this file, one would have to manually
rerun CMake to generate a build system incorporating the new file.
break
Break from an enclosing foreach or while loop.
break()
Breaks from an enclosing foreach loop or while loop
build_command
Get the command line that will build this project.
build_command(<variable> <makecommand>)
Sets the given <variable> to a string containing the command that will
build this project from the root of the build tree using the build
tool given by <makecommand>. <makecommand> should be msdev, nmake,
make or one of the end user build tools. This is useful for
configuring testing systems.
cmake_minimum_required
Set the minimum required version of cmake for a project.
cmake_minimum_required(VERSION major[.minor[.patch]]
[FATAL_ERROR])
If the current version of CMake is lower than that required it will
stop processing the project and report an error. When a version
higher than 2.4 is specified the command implicitly invokes
cmake_policy(VERSION major[.minor[.patch]])
which sets the cmake policy version level to the version specified.
When version 2.4 or lower is given the command implicitly invokes
cmake_policy(VERSION 2.4)
which enables compatibility features for CMake 2.4 and lower.
The FATAL_ERROR option is accepted but ignored by CMake 2.6 and
higher. It should be specified so CMake versions 2.4 and lower fail
with an error instead of just a warning.
cmake_policy
Manage CMake Policy settings.
As CMake evolves it is sometimes necessary to change existing behavior
in order to fix bugs or improve implementations of existing features.
The CMake Policy mechanism is designed to help keep existing projects
building as new versions of CMake introduce changes in behavior. Each
new policy (behavioral change) is given an identifier of the form
"CMP<NNNN>" where "<NNNN>" is an integer index. Documentation
associated with each policy describes the OLD and NEW behavior and the
reason the policy was introduced. Projects may set each policy to
select the desired behavior. When CMake needs to know which behavior
to use it checks for a setting specified by the project. If no
setting is available the OLD behavior is assumed and a warning is
produced requesting that the policy be set.
The cmake_policy command is used to set policies to OLD or NEW
behavior. While setting policies individually is supported, we
encourage projects to set policies based on CMake versions.
cmake_policy(VERSION major.minor[.patch])
Specify that the current CMake list file is written for the given
version of CMake. All policies introduced in the specified version or
earlier will be set to use NEW behavior. All policies introduced
after the specified version will be unset. This effectively requests
behavior preferred as of a given CMake version and tells newer CMake
versions to warn about their new policies. The policy version
specified must be at least 2.4 or the command will report an error.
In order to get compatibility features supporting versions earlier
than 2.4 see documentation of policy CMP0001.
cmake_policy(SET CMP<NNNN> NEW)
cmake_policy(SET CMP<NNNN> OLD)
Tell CMake to use the OLD or NEW behavior for a given policy.
Projects depending on the old behavior of a given policy may silence a
policy warning by setting the policy state to OLD. Alternatively one
may fix the project to work with the new behavior and set the policy
state to NEW.
cmake_policy(GET CMP<NNNN> <variable>)
Check whether a given policy is set to OLD or NEW behavior. The
output variable value will be "OLD" or "NEW" if the policy is set, and
empty otherwise.
CMake keeps policy settings on a stack, so changes made by the
cmake_policy command affect only the top of the stack. A new entry on
the policy stack is managed automatically for each subdirectory to
protect its parents and siblings. CMake also manages a new entry for
scripts loaded by include() and find_package() commands except when
invoked with the NO_POLICY_SCOPE option (see also policy CMP0011).
The cmake_policy command provides an interface to manage custom
entries on the policy stack:
cmake_policy(PUSH)
cmake_policy(POP)
Each PUSH must have a matching POP to erase any changes. This is
useful to make temporary changes to policy settings.
Functions and macros record policy settings when they are created and
use the pre-record policies when they are invoked. If the function or
macro implementation sets policies, the changes automatically
propagate up through callers until they reach the closest nested
policy stack entry.
configure_file
Copy a file to another location and modify its contents.
configure_file(<input> <output>
[COPYONLY] [ESCAPE_QUOTES] [@ONLY])
Copies a file <input> to file <output> and substitutes variable values
referenced in the file content. If <input> is a relative path it is
evaluated with respect to the current source directory. The <input>
must be a file, not a directory. If <output> is a relative path it is
evaluated with respect to the current binary directory. If <output>
names an existing directory the input file is placed in that directory
with its original name.
This command replaces any variables in the input file referenced as
${VAR} or @VAR@ with their values as determined by CMake. If a
variable is not defined, it will be replaced with nothing. If
COPYONLY is specified, then no variable expansion will take place. If
ESCAPE_QUOTES is specified then any substituted quotes will be C-style
escaped. The file will be configured with the current values of CMake
variables. If @ONLY is specified, only variables of the form @VAR@
will be replaces and ${VAR} will be ignored. This is useful for
configuring scripts that use ${VAR}. Any occurrences of #cmakedefine
VAR will be replaced with either #define VAR or /* #undef VAR */
depending on the setting of VAR in CMake. Any occurrences of
#cmakedefine01 VAR will be replaced with either #define VAR 1 or
#define VAR 0 depending on whether VAR evaluates to TRUE or FALSE in
CMake
create_test_sourcelist
Create a test driver and source list for building test programs.
create_test_sourcelist(sourceListName driverName
test1 test2 test3
EXTRA_INCLUDE include.h
FUNCTION function)
A test driver is a program that links together many small tests into a
single executable. This is useful when building static executables
with large libraries to shrink the total required size. The list of
source files needed to build the test driver will be in
sourceListName. DriverName is the name of the test driver program.
The rest of the arguments consist of a list of test source files, can
be semicolon separated. Each test source file should have a function
in it that is the same name as the file with no extension (foo.cxx
should have int foo(int, char*[]);) DriverName will be able to call
each of the tests by name on the command line. If EXTRA_INCLUDE is
specified, then the next argument is included into the generated file.
If FUNCTION is specified, then the next argument is taken as a
function name that is passed a pointer to ac and av. This can be used
to add extra command line processing to each test. The cmake variable
CMAKE_TESTDRIVER_BEFORE_TESTMAIN can be set to have code that will be
placed directly before calling the test main function.
CMAKE_TESTDRIVER_AFTER_TESTMAIN can be set to have code that will be
placed directly after the call to the test main function.
define_property
Define and document custom properties.
define_property(<GLOBAL | DIRECTORY | TARGET | SOURCE |
TEST | VARIABLE | CACHED_VARIABLE>
PROPERTY <name> [INHERITED]
BRIEF_DOCS <brief-doc> [docs...]
FULL_DOCS <full-doc> [docs...])
Define one property in a scope for use with the set_property and
get_property commands. This is primarily useful to associate
documentation with property names that may be retrieved with the
get_property command. The first argument determines the kind of scope
in which the property should be used. It must be one of the
following:
GLOBAL = associated with the global namespace
DIRECTORY = associated with one directory
TARGET = associated with one target
SOURCE = associated with one source file
TEST = associated with a test named with add_test
VARIABLE = documents a CMake language variable
CACHED_VARIABLE = documents a CMake cache variable
Note that unlike set_property and get_property no actual scope needs
to be given; only the kind of scope is important.
The required PROPERTY option is immediately followed by the name of
the property being defined.
If the INHERITED option then the get_property command will chain up to
the next higher scope when the requested property is not set in the
scope given to the command. DIRECTORY scope chains to GLOBAL.
TARGET, SOURCE, and TEST chain to DIRECTORY.
The BRIEF_DOCS and FULL_DOCS options are followed by strings to be
associated with the property as its brief and full documentation.
Corresponding options to the get_property command will retrieve the
documentation.
else
Starts the else portion of an if block.
else(expression)
See the if command.
elseif
Starts the elseif portion of an if block.
elseif(expression)
See the if command.
enable_language
Enable a language (CXX/C/Fortran/etc)
enable_language(languageName [OPTIONAL] )
This command enables support for the named language in CMake. This is
the same as the project command but does not create any of the extra
variables that are created by the project command. Example languages
are CXX, C, Fortran. If OPTIONAL is used, use the
CMAKE_<languageName>_COMPILER_WORKS variable to check whether the
language has been enabled successfully.
enable_testing
Enable testing for current directory and below.
enable_testing()
Enables testing for this directory and below. See also the add_test
command. Note that ctest expects to find a test file in the build
directory root. Therefore, this command should be in the source
directory root.
endforeach
Ends a list of commands in a FOREACH block.
endforeach(expression)
See the FOREACH command.
endfunction
Ends a list of commands in a function block.
endfunction(expression)
See the function command.
endif
Ends a list of commands in an if block.

endwhile
Ends a list of commands in a while block.
endwhile(expression)

execute_process
Execute one or more child processes.
execute_process(COMMAND <cmd1> [args1...]]
[COMMAND <cmd2> [args2...] [...]]
[WORKING_DIRECTORY <directory>]
[TIMEOUT <seconds>]
[RESULT_VARIABLE <variable>]
[OUTPUT_VARIABLE <variable>]
[ERROR_VARIABLE <variable>]
[INPUT_FILE <file>]
[OUTPUT_FILE <file>]
[ERROR_FILE <file>]
[OUTPUT_QUIET]
[ERROR_QUIET]
[OUTPUT_STRIP_TRAILING_WHITESPACE]
[ERROR_STRIP_TRAILING_WHITESPACE])
Runs the given sequence of one or more commands with the standard
output of each process piped to the standard input of the next. A
single standard error pipe is used for all processes. If
WORKING_DIRECTORY is given the named directory will be set as the
current working directory of the child processes. If TIMEOUT is given
the child processes will be terminated if they do not finish in the
specified number of seconds (fractions are allowed). If
RESULT_VARIABLE is given the variable will be set to contain the
result of running the processes. This will be an integer return code
from the last child or a string describing an error condition. If
OUTPUT_VARIABLE or ERROR_VARIABLE are given the variable named will be
set with the contents of the standard output and standard error pipes
respectively. If the same variable is named for both pipes their
output will be merged in the order produced. If INPUT_FILE,
OUTPUT_FILE, or ERROR_FILE is given the file named will be attached to
the standard input of the first process, standard output of the last
process, or standard error of all processes respectively. If
OUTPUT_QUIET or ERROR_QUIET is given then the standard output or
standard error results will be quietly ignored. If more than one
OUTPUT_* or ERROR_* option is given for the same pipe the precedence
is not specified. If no OUTPUT_* or ERROR_* options are given the
output will be shared with the corresponding pipes of the CMake
process itself.
The execute_process command is a newer more powerful version of
exec_program, but the old command has been kept for compatibility.
export
Export targets from the build tree for use by outside projects.
export(TARGETS [target1 [target2 [...]]] [NAMESPACE <namespace>]
[APPEND] FILE <filename>)
Create a file <filename> that may be included by outside projects to
import targets from the current project's build tree. This is useful
during cross-compiling to build utility executables that can run on
the host platform in one project and then import them into another
project being compiled for the target platform. If the NAMESPACE
option is given the <namespace> string will be prepended to all target
names written to the file. If the APPEND option is given the
generated code will be appended to the file instead of overwriting it.
If a library target is included in the export but a target to which it
links is not included the behavior is unspecified.
The file created by this command is specific to the build tree and
should never be installed. See the install(EXPORT) command to export
targets from an installation tree.
export(PACKAGE <name>)
Store the current build directory in the CMake user package registry
for package <name>. The find_package command may consider the
directory while searching for package <name>. This helps dependent
projects find and use a package from the current project's build tree
without help from the user. Note that the entry in the package
registry that this command creates works only in conjunction with a
package configuration file (<name>Config.cmake) that works with the
build tree.
file
File manipulation command.
file(WRITE filename "message to write"... )
file(APPEND filename "message to write"... )
file(READ filename variable [LIMIT numBytes] [OFFSET offset] [HEX])
file(STRINGS filename variable [LIMIT_COUNT num]
[LIMIT_INPUT numBytes] [LIMIT_OUTPUT numBytes]
[LENGTH_MINIMUM numBytes] [LENGTH_MAXIMUM numBytes]
[NEWLINE_CONSUME] [REGEX regex]
[NO_HEX_CONVERSION])
file(GLOB variable [RELATIVE path] [globbing expressions]...)
file(GLOB_RECURSE variable [RELATIVE path]
[FOLLOW_SYMLINKS] [globbing expressions]...)
file(RENAME <oldname> <newname>)
file(REMOVE [file1 ...])
file(REMOVE_RECURSE [file1 ...])
file(MAKE_DIRECTORY [directory1 directory2 ...])
file(RELATIVE_PATH variable directory file)
file(TO_CMAKE_PATH path result)
file(TO_NATIVE_PATH path result)
file(DOWNLOAD url file [TIMEOUT timeout] [STATUS status] [LOG log])
WRITE will write a message into a file called 'filename'. It
overwrites the file if it already exists, and creates the file if it
does not exist.
APPEND will write a message into a file same as WRITE, except it will
append it to the end of the file
READ will read the content of a file and store it into the variable.
It will start at the given offset and read up to numBytes. If the
argument HEX is given, the binary data will be converted to
hexadecimal representation and this will be stored in the variable.
STRINGS will parse a list of ASCII strings from a file and store it in
a variable. Binary data in the file are ignored. Carriage return
(CR) characters are ignored. It works also for Intel Hex and Motorola
S-record files, which are automatically converted to binary format
when reading them. Disable this using NO_HEX_CONVERSION.
LIMIT_COUNT sets the maximum number of strings to return. LIMIT_INPUT
sets the maximum number of bytes to read from the input file.
LIMIT_OUTPUT sets the maximum number of bytes to store in the output
variable. LENGTH_MINIMUM sets the minimum length of a string to
return. Shorter strings are ignored. LENGTH_MAXIMUM sets the maximum
length of a string to return. Longer strings are split into strings
no longer than the maximum length. NEWLINE_CONSUME allows newlines to
be included in strings instead of terminating them.
REGEX specifies a regular expression that a string must match to be
returned. Typical usage
file(STRINGS myfile.txt myfile)
stores a list in the variable "myfile" in which each item is a line
from the input file.
GLOB will generate a list of all files that match the globbing
expressions and store it into the variable. Globbing expressions are
similar to regular expressions, but much simpler. If RELATIVE flag is
specified for an expression, the results will be returned as a
relative path to the given path.
Examples of globbing expressions include:
*.cxx - match all files with extension cxx
*.vt? - match all files with extension vta,...,vtz
f[3-5].txt - match files f3.txt, f4.txt, f5.txt
GLOB_RECURSE will generate a list similar to the regular GLOB, except
it will traverse all the subdirectories of the matched directory and
match the files. Subdirectories that are symlinks are only traversed
if FOLLOW_SYMLINKS is given or cmake policy CMP0009 is not set to NEW.
See cmake --help-policy CMP0009 for more information.
Examples of recursive globbing include:
/dir/*.py - match all python files in /dir and subdirectories
MAKE_DIRECTORY will create the given directories, also if their parent
directories don't exist yet
RENAME moves a file or directory within a filesystem, replacing the
destination atomically.
REMOVE will remove the given files, also in subdirectories
REMOVE_RECURSE will remove the given files and directories, also
non-empty directories
RELATIVE_PATH will determine relative path from directory to the given
file.
TO_CMAKE_PATH will convert path into a cmake style path with unix /.
The input can be a single path or a system path like "$ENV{PATH}".
Note the double quotes around the ENV call TO_CMAKE_PATH only takes
one argument.
TO_NATIVE_PATH works just like TO_CMAKE_PATH, but will convert from a
cmake style path into the native path style \ for windows and / for
UNIX.
DOWNLOAD will download the given URL to the given file. If LOG var is
specified a log of the download will be put in var. If STATUS var is
specified the status of the operation will be put in var. The status
is returned in a list of length 2. The first element is the numeric
return value for the operation, and the second element is a string
value for the error. A 0 numeric error means no error in the
operation. If TIMEOUT time is specified, the operation will timeout
after time seconds, time should be specified as an integer.
The file() command also provides COPY and INSTALL signatures:
file(<COPY|INSTALL> files... DESTINATION <dir>
[FILE_PERMISSIONS permissions...]
[DIRECTORY_PERMISSIONS permissions...]
[NO_SOURCE_PERMISSIONS] [USE_SOURCE_PERMISSIONS]
[FILES_MATCHING]
[[PATTERN <pattern> | REGEX <regex>]
[EXCLUDE] [PERMISSIONS permissions...]] [...])
The COPY signature copies files, directories, and symlinks to a
destination folder. Relative input paths are evaluated with respect
to the current source directory, and a relative destination is
evaluated with respect to the current build directory. Copying
preserves input file timestamps, and optimizes out a file if it exists
at the destination with the same timestamp. Copying preserves input
permissions unless explicit permissions or NO_SOURCE_PERMISSIONS are
given (default is USE_SOURCE_PERMISSIONS). See the install(DIRECTORY)
command for documentation of permissions, PATTERN, REGEX, and EXCLUDE
options.
The INSTALL signature differs slightly from COPY: it prints status
messages, and NO_SOURCE_PERMISSIONS is default. Installation scripts
generated by the install() command use this signature (with some
undocumented options for internal use).
find_file
Find the full path to a file.
find_file(<VAR> name1 [path1 path2 ...])
This is the short-hand signature for the command that is sufficient in
many cases. It is the same as find_file(<VAR> name1 [PATHS path1
path2 ...])
find_file(
<VAR>
name | NAMES name1 [name2 ...]
[HINTS path1 [path2 ... ENV var]]
[PATHS path1 [path2 ... ENV var]]
[PATH_SUFFIXES suffix1 [suffix2 ...]]
[DOC "cache documentation string"]
[NO_DEFAULT_PATH]
[NO_CMAKE_ENVIRONMENT_PATH]
[NO_CMAKE_PATH]
[NO_SYSTEM_ENVIRONMENT_PATH]
[NO_CMAKE_SYSTEM_PATH]
[CMAKE_FIND_ROOT_PATH_BOTH |
ONLY_CMAKE_FIND_ROOT_PATH |
NO_CMAKE_FIND_ROOT_PATH]
)
This command is used to find a full path to named file. A cache entry
named by <VAR> is created to store the result of this command. If the
full path to a file is found the result is stored in the variable and
the search will not be repeated unless the variable is cleared. If
nothing is found, the result will be <VAR>-NOTFOUND, and the search
will be attempted again the next time find_file is invoked with the
same variable. The name of the full path to a file that is searched
for is specified by the names listed after the NAMES argument.
Additional search locations can be specified after the PATHS argument.
If ENV var is found in the HINTS or PATHS section the environment
variable var will be read and converted from a system environment
variable to a cmake style list of paths. For example ENV PATH would
be a way to list the system path variable. The argument after DOC
will be used for the documentation string in the cache. PATH_SUFFIXES
specifies additional subdirectories to check below each search path.
If NO_DEFAULT_PATH is specified, then no additional paths are added to
the search. If NO_DEFAULT_PATH is not specified, the search process
is as follows:
1. Search paths specified in cmake-specific cache variables. These
are intended to be used on the command line with a -DVAR=value. This
can be skipped if NO_CMAKE_PATH is passed.
<prefix>/include for each <prefix> in CMAKE_PREFIX_PATH
CMAKE_INCLUDE_PATH
CMAKE_FRAMEWORK_PATH
2. Search paths specified in cmake-specific environment variables.
These are intended to be set in the user's shell configuration. This
can be skipped if NO_CMAKE_ENVIRONMENT_PATH is passed.
<prefix>/include for each <prefix> in CMAKE_PREFIX_PATH
CMAKE_INCLUDE_PATH
CMAKE_FRAMEWORK_PATH
3. Search the paths specified by the HINTS option. These should be
paths computed by system introspection, such as a hint provided by the
location of another item already found. Hard-coded guesses should be
specified with the PATHS option.
4. Search the standard system environment variables. This can be
skipped if NO_SYSTEM_ENVIRONMENT_PATH is an argument.
PATH
INCLUDE
5. Search cmake variables defined in the Platform files for the
current system. This can be skipped if NO_CMAKE_SYSTEM_PATH is
passed.
<prefix>/include for each <prefix> in CMAKE_SYSTEM_PREFIX_PATH
CMAKE_SYSTEM_INCLUDE_PATH
CMAKE_SYSTEM_FRAMEWORK_PATH
6. Search the paths specified by the PATHS option or in the
short-hand version of the command. These are typically hard-coded
guesses.
On Darwin or systems supporting OS X Frameworks, the cmake variable
CMAKE_FIND_FRAMEWORK can be set to empty or one of the following:
"FIRST" - Try to find frameworks before standard
libraries or headers. This is the default on Darwin.
"LAST" - Try to find frameworks after standard
libraries or headers.
"ONLY" - Only try to find frameworks.
"NEVER" - Never try to find frameworks.
On Darwin or systems supporting OS X Application Bundles, the cmake
variable CMAKE_FIND_APPBUNDLE can be set to empty or one of the
following:
"FIRST" - Try to find application bundles before standard
programs. This is the default on Darwin.
"LAST" - Try to find application bundles after standard
programs.
"ONLY" - Only try to find application bundles.
"NEVER" - Never try to find application bundles.
The CMake variable CMAKE_FIND_ROOT_PATH specifies one or more
directories to be prepended to all other search directories. This
effectively "re-roots" the entire search under given locations. By
default it is empty. It is especially useful when cross-compiling to
point to the root directory of the target environment and CMake will
search there too. By default at first the directories listed in
CMAKE_FIND_ROOT_PATH and then the non-rooted directories will be
searched. The default behavior can be adjusted by setting
CMAKE_FIND_ROOT_PATH_MODE_INCLUDE. This behavior can be manually
overridden on a per-call basis. By using CMAKE_FIND_ROOT_PATH_BOTH
the search order will be as described above. If
NO_CMAKE_FIND_ROOT_PATH is used then CMAKE_FIND_ROOT_PATH will not be
used. If ONLY_CMAKE_FIND_ROOT_PATH is used then only the re-rooted
directories will be searched.
The default search order is designed to be most-specific to
least-specific for common use cases. Projects may override the order
by simply calling the command multiple times and using the NO_*
options:
find_file(<VAR> NAMES name PATHS paths... NO_DEFAULT_PATH)
find_file(<VAR> NAMES name)
Once one of the calls succeeds the result variable will be set and
stored in the cache so that no call will search again.
find_library
Find a library.
find_library(<VAR> name1 [path1 path2 ...])
This is the short-hand signature for the command that is sufficient in
many cases. It is the same as find_library(<VAR> name1 [PATHS path1
path2 ...])
find_library(
<VAR>
name | NAMES name1 [name2 ...]
[HINTS path1 [path2 ... ENV var]]
[PATHS path1 [path2 ... ENV var]]
[PATH_SUFFIXES suffix1 [suffix2 ...]]
[DOC "cache documentation string"]
[NO_DEFAULT_PATH]
[NO_CMAKE_ENVIRONMENT_PATH]
[NO_CMAKE_PATH]
[NO_SYSTEM_ENVIRONMENT_PATH]
[NO_CMAKE_SYSTEM_PATH]
[CMAKE_FIND_ROOT_PATH_BOTH |
ONLY_CMAKE_FIND_ROOT_PATH |
NO_CMAKE_FIND_ROOT_PATH]
)
This command is used to find a library. A cache entry named by <VAR>
is created to store the result of this command. If the library is
found the result is stored in the variable and the search will not be
repeated unless the variable is cleared. If nothing is found, the
result will be <VAR>-NOTFOUND, and the search will be attempted again
the next time find_library is invoked with the same variable. The
name of the library that is searched for is specified by the names
listed after the NAMES argument. Additional search locations can be
specified after the PATHS argument. If ENV var is found in the HINTS
or PATHS section the environment variable var will be read and
converted from a system environment variable to a cmake style list of
paths. For example ENV PATH would be a way to list the system path
variable. The argument after DOC will be used for the documentation
string in the cache. PATH_SUFFIXES specifies additional
subdirectories to check below each search path.
If NO_DEFAULT_PATH is specified, then no additional paths are added to
the search. If NO_DEFAULT_PATH is not specified, the search process
is as follows:
1. Search paths specified in cmake-specific cache variables. These
are intended to be used on the command line with a -DVAR=value. This
can be skipped if NO_CMAKE_PATH is passed.

CMAKE_LIBRARY_PATH
CMAKE_FRAMEWORK_PATH
2. Search paths specified in cmake-specific environment variables.
These are intended to be set in the user's shell configuration. This
can be skipped if NO_CMAKE_ENVIRONMENT_PATH is passed.

find_library(<VAR> NAMES name)
Once one of the calls succeeds the result variable will be set and
stored in the cache so that no call will search again.
If the library found is a framework, then VAR will be set to the full
path to the framework <fullPath>/A.framework. When a full path to a
framework is used as a library, CMake will use a -framework A, and a
-F<fullPath> to link the framework to the target.
find_package
Load settings for an external project.
find_package(<package> [version] [EXACT] [QUIET]
[[REQUIRED|COMPONENTS] [components...]]
[NO_POLICY_SCOPE])
Finds and loads settings from an external project. <package>_FOUND
will be set to indicate whether the package was found. When the
package is found package-specific information is provided through
variables documented by the package itself. The QUIET option disables
messages if the package cannot be found. The REQUIRED option stops
processing with an error message if the package cannot be found. A
package-specific list of components may be listed after the REQUIRED
option or after the COMPONENTS option if no REQUIRED option is given.
The [version] argument requests a version with which the package found
should be compatible (format is major[.minor[.patch[.tweak]]]). The
EXACT option requests that the version be matched exactly. If no
[version] is given to a recursive invocation inside a find-module, the
[version] and EXACT arguments are forwarded automatically from the
outer call. Version support is currently provided only on a
package-by-package basis (details below).
User code should generally look for packages using the above simple
signature. The remainder of this command documentation specifies the
full command signature and details of the search process. Project
maintainers wishing to provide a package to be found by this command
are encouraged to read on.
The command has two modes by which it searches for packages: "Module"
mode and "Config" mode. Module mode is available when the command is
invoked with the above reduced signature. CMake searches for a file
called "Find<package>.cmake" in the CMAKE_MODULE_PATH followed by the
CMake installation. If the file is found, it is read and processed by
CMake. It is responsible for finding the package, checking the
version, and producing any needed messages. Many find-modules provide
limited or no support for versioning; check the module documentation.
If no module is found the command proceeds to Config mode.
The complete Config mode command signature is:
find_package(<package> [version] [EXACT] [QUIET]
[[REQUIRED|COMPONENTS] [components...]] [NO_MODULE]
[NO_POLICY_SCOPE]
[NAMES name1 [name2 ...]]
[CONFIGS config1 [config2 ...]]
[HINTS path1 [path2 ... ]]
[PATHS path1 [path2 ... ]]
[PATH_SUFFIXES suffix1 [suffix2 ...]]
[NO_DEFAULT_PATH]
[NO_CMAKE_ENVIRONMENT_PATH]
[NO_CMAKE_PATH]
[NO_SYSTEM_ENVIRONMENT_PATH]
[NO_CMAKE_PACKAGE_REGISTRY]
[NO_CMAKE_BUILDS_PATH]
[NO_CMAKE_SYSTEM_PATH]
[CMAKE_FIND_ROOT_PATH_BOTH |
ONLY_CMAKE_FIND_ROOT_PATH |
NO_CMAKE_FIND_ROOT_PATH])
The NO_MODULE option may be used to skip Module mode explicitly. It
is also implied by use of options not specified in the reduced
signature.
Config mode attempts to locate a configuration file provided by the
package to be found. A cache entry called <package>_DIR is created to
hold the directory containing the file. By default the command
searches for a package with the name <package>. If the NAMES option
is given the names following it are used instead of <package>. The
command searches for a file called "<name>Config.cmake" or
"<lower-case-name>-config.cmake" for each name specified. A
replacement set of possible configuration file names may be given
using the CONFIGS option. The search procedure is specified below.
Once found, the configuration file is read and processed by CMake.
Since the file is provided by the package it already knows the
location of package contents. The full path to the configuration file
is stored in the cmake variable <package>_CONFIG.
If the package configuration file cannot be found CMake will generate
an error describing the problem unless the QUIET argument is
specified. If REQUIRED is specified and the package is not found a
fatal error is generated and the configure step stops executing. If
<package>_DIR has been set to a directory not containing a
configuration file CMake will ignore it and search from scratch.
When the [version] argument is given Config mode will only find a
version of the package that claims compatibility with the requested
version (format is major[.minor[.patch[.tweak]]]). If the EXACT
option is given only a version of the package claiming an exact match
of the requested version may be found. CMake does not establish any
convention for the meaning of version numbers. Package version
numbers are checked by "version" files provided by the packages
themselves. For a candidate package configuration file
"<config-file>.cmake" the corresponding version file is located next
to it and named either "<config-file>-version.cmake" or
"<config-file>Version.cmake". If no such version file is available
then the configuration file is assumed to not be compatible with any
requested version. When a version file is found it is loaded to check
the requested version number. The version file is loaded in a nested
scope in which the following variables have been defined:
PACKAGE_FIND_NAME = the <package> name
PACKAGE_FIND_VERSION = full requested version string
PACKAGE_FIND_VERSION_MAJOR = major version if requested, else 0
PACKAGE_FIND_VERSION_MINOR = minor version if requested, else 0
PACKAGE_FIND_VERSION_PATCH = patch version if requested, else 0
PACKAGE_FIND_VERSION_TWEAK = tweak version if requested, else 0
PACKAGE_FIND_VERSION_COUNT = number of version components, 0 to 4
The version file checks whether it satisfies the requested version and
sets these variables:
PACKAGE_VERSION = full provided version string
PACKAGE_VERSION_EXACT = true if version is exact match
PACKAGE_VERSION_COMPATIBLE = true if version is compatible
PACKAGE_VERSION_UNSUITABLE = true if unsuitable as any version
These variables are checked by the find_package command to determine
whether the configuration file provides an acceptable version. They
are not available after the find_package call returns. If the version
is acceptable the following variables are set:
<package>_VERSION = full provided version string
<package>_VERSION_MAJOR = major version if provided, else 0
<package>_VERSION_MINOR = minor version if provided, else 0
<package>_VERSION_PATCH = patch version if provided, else 0
<package>_VERSION_TWEAK = tweak version if provided, else 0
<package>_VERSION_COUNT = number of version components, 0 to 4
and the corresponding package configuration file is loaded. When
multiple package configuration files are available whose version files
claim compatibility with the version requested it is unspecified which
one is chosen. No attempt is made to choose a highest or closest
version number.
Config mode provides an elaborate interface and search procedure.
Much of the interface is provided for completeness and for use
internally by find-modules loaded by Module mode. Most user code
should simply call
find_package(<package> [major[.minor]] [EXACT] [REQUIRED|QUIET])
in order to find a package. Package maintainers providing CMake
package configuration files are encouraged to name and install them
such that the procedure outlined below will find them without
requiring use of additional options.
CMake constructs a set of possible installation prefixes for the
package. Under each prefix several directories are searched for a
configuration file. The tables below show the directories searched.
Each entry is meant for installation trees following Windows (W), UNIX
(U), or Apple (A) conventions.
<prefix>/ (W)
<prefix>/(cmake|CMake)/ (W)
<prefix>/<name>*/ (W)
<prefix>/<name>*/(cmake|CMake)/ (W)
<prefix>/(share|lib)/cmake/<name>*/ (U)
<prefix>/(share|lib)/<name>*/ (U)
<prefix>/(share|lib)/<name>*/(cmake|CMake)/ (U)
On systems supporting OS X Frameworks and Application Bundles the
following directories are searched for frameworks or bundles
containing a configuration file:
<prefix>/<name>.framework/Resources/ (A)
<prefix>/<name>.framework/Resources/CMake/ (A)
<prefix>/<name>.framework/Versions/*/Resources/ (A)
<prefix>/<name>.framework/Versions/*/Resources/CMake/ (A)
<prefix>/<name>.app/Contents/Resources/ (A)
<prefix>/<name>.app/Contents/Resources/CMake/ (A)
In all cases the <name> is treated as case-insensitive and corresponds
to any of the names specified (<package> or names given by NAMES). If
PATH_SUFFIXES is specified the suffixes are appended to each (W) or
(U) directory entry one-by-one.
This set of directories is intended to work in cooperation with
projects that provide configuration files in their installation trees.
Directories above marked with (W) are intended for installations on
Windows where the prefix may point at the top of an application's
installation directory. Those marked with (U) are intended for
installations on UNIX platforms where the prefix is shared by multiple
packages. This is merely a convention, so all (W) and (U) directories
are still searched on all platforms. Directories marked with (A) are
intended for installations on Apple platforms. The cmake variables
CMAKE_FIND_FRAMEWORK and CMAKE_FIND_APPBUNDLE determine the order of
preference as specified below.
The set of installation prefixes is constructed using the following
steps. If NO_DEFAULT_PATH is specified all NO_* options are enabled.
1. Search paths specified in cmake-specific cache variables. These
are intended to be used on the command line with a -DVAR=value. This
can be skipped if NO_CMAKE_PATH is passed.
CMAKE_PREFIX_PATH
CMAKE_FRAMEWORK_PATH
CMAKE_APPBUNDLE_PATH
2. Search paths specified in cmake-specific environment variables.
These are intended to be set in the user's shell configuration. This
can be skipped if NO_CMAKE_ENVIRONMENT_PATH is passed.
CMAKE_PREFIX_PATH
CMAKE_FRAMEWORK_PATH
CMAKE_APPBUNDLE_PATH
3. Search paths specified by the HINTS option. These should be paths
computed by system introspection, such as a hint provided by the
location of another item already found. Hard-coded guesses should be
specified with the PATHS option.
4. Search the standard system environment variables. This can be
skipped if NO_SYSTEM_ENVIRONMENT_PATH is passed. Path entries ending
in "/bin" or "/sbin" are automatically converted to their parent
directories.
PATH
5. Search project build trees recently configured in a CMake GUI.
This can be skipped if NO_CMAKE_BUILDS_PATH is passed. It is intended
for the case when a user is building multiple dependent projects one
after another.
6. Search paths stored in the CMake user package registry. This can
be skipped if NO_CMAKE_PACKAGE_REGISTRY is passed. Paths are stored
in the registry when CMake configures a project that invokes
export(PACKAGE <name>). See the export(PACKAGE) command documentation
for more details.
7. Search cmake variables defined in the Platform files for the
current system. This can be skipped if NO_CMAKE_SYSTEM_PATH is
passed.
CMAKE_SYSTEM_PREFIX_PATH
CMAKE_SYSTEM_FRAMEWORK_PATH
CMAKE_SYSTEM_APPBUNDLE_PATH
8. Search paths specified by the PATHS option. These are typically
hard-coded guesses.
On Darwin or systems supporting OS X Frameworks, the cmake variable
CMAKE_FIND_FRAMEWORK can be set to empty or one of the following:
"FIRST" - Try to find frameworks before standard
libraries or headers. This is the default on Darwin.
"LAST" - Try to find frameworks after standard
libraries or headers.
"ONLY" - Only try to find frameworks.
"NEVER" - Never try to find frameworks.
On Darwin or systems supporting OS X Application Bundles, the cmake
variable CMAKE_FIND_APPBUNDLE can be set to empty or one of the
following:
"FIRST" - Try to find application bundles before standard
programs. This is the default on Darwin.
"LAST" - Try to find application bundles after standard
programs.
"ONLY" - Only try to find application bundles.
"NEVER" - Never try to find application bundles.
The CMake variable CMAKE_FIND_ROOT_PATH specifies one or more
directories to be prepended to all other search directories. This
effectively "re-roots" the entire search under given locations. By
default it is empty. It is especially useful when cross-compiling to
point to the root directory of the target environment and CMake will
search there too. By default at first the directories listed in
CMAKE_FIND_ROOT_PATH and then the non-rooted directories will be
searched. The default behavior can be adjusted by setting
CMAKE_FIND_ROOT_PATH_MODE_PACKAGE. This behavior can be manually
overridden on a per-call basis. By using CMAKE_FIND_ROOT_PATH_BOTH
the search order will be as described above. If
NO_CMAKE_FIND_ROOT_PATH is used then CMAKE_FIND_ROOT_PATH will not be
used. If ONLY_CMAKE_FIND_ROOT_PATH is used then only the re-rooted
directories will be searched.
The default search order is designed to be most-specific to
least-specific for common use cases. Projects may override the order
by simply calling the command multiple times and using the NO_*
options:
find_package(<package> PATHS paths... NO_DEFAULT_PATH)
find_package(<package>)
Once one of the calls succeeds the result variable will be set and
stored in the cache so that no call will search again.
See the cmake_policy() command documentation for discussion of the
NO_POLICY_SCOPE option.
find_path
Find the directory containing a file.
find_path(<VAR> name1 [path1 path2 ...])
This is the short-hand signature for the command that is sufficient in
many cases. It is the same as find_path(<VAR> name1 [PATHS path1
path2 ...])
find_path(
<VAR>
name | NAMES name1 [name2 ...]
[HINTS path1 [path2 ... ENV var]]
[PATHS path1 [path2 ... ENV var]]
[PATH_SUFFIXES suffix1 [suffix2 ...]]
[DOC "cache documentation string"]
[NO_DEFAULT_PATH]
[NO_CMAKE_ENVIRONMENT_PATH]
[NO_CMAKE_PATH]
[NO_SYSTEM_ENVIRONMENT_PATH]
[NO_CMAKE_SYSTEM_PATH]
[CMAKE_FIND_ROOT_PATH_BOTH |
ONLY_CMAKE_FIND_ROOT_PATH |
NO_CMAKE_FIND_ROOT_PATH]
)
This command is used to find a directory containing the named file. A
cache entry named by <VAR> is created to store the result of this
command. If the file in a directory is found the result is stored in
the variable and the search will not be repeated unless the variable
is cleared. If nothing is found, the result will be <VAR>-NOTFOUND,
and the search will be attempted again the next time find_path is
invoked with the same variable. The name of the file in a directory
that is searched for is specified by the names listed after the NAMES
argument. Additional search locations can be specified after the
PATHS argument. If ENV var is found in the HINTS or PATHS section the
environment variable var will be read and converted from a system
environment variable to a cmake style list of paths. For example ENV
PATH would be a way to list the system path variable. The argument
after DOC will be used for the documentation string in the cache.
PATH_SUFFIXES specifies additional subdirectories to check below each
search path.
If NO_DEFAULT_PATH is specified, then no additional paths are added to
the search. If NO_DEFAULT_PATH is not specified, the search process
is as follows:
1. Search paths specified in cmake-specific cache variables. These
are intended to be used on the command line with a -DVAR=value. This
can be skipped if NO_CMAKE_PATH is passed.
<prefix>/include for each <prefix> in CMAKE_PREFIX_PATH
CMAKE_INCLUDE_PATH
CMAKE_FRAMEWORK_PATH
2. Search paths specified in cmake-specific environment variables.
These are intended to be set in the user's shell configuration. This
can be skipped if NO_CMAKE_ENVIRONMENT_PATH is passed.
<prefix>/include for each <prefix> in CMAKE_PREFIX_PATH
CMAKE_INCLUDE_PATH
CMAKE_FRAMEWORK_PATH
3. Search the paths specified by the HINTS option. These should be
paths computed by system introspection, such as a hint provided by the
location of another item already found. Hard-coded guesses should be
specified with the PATHS option.
4. Search the standard system environment variables. This can be
skipped if NO_SYSTEM_ENVIRONMENT_PATH is an argument.
PATH
INCLUDE
5. Search cmake variables defined in the Platform files for the
current system. This can be skipped if NO_CMAKE_SYSTEM_PATH is
passed.
<prefix>/include for each <prefix> in CMAKE_SYSTEM_PREFIX_PATH
CMAKE_SYSTEM_INCLUDE_PATH
CMAKE_SYSTEM_FRAMEWORK_PATH
6. Search the paths specified by the PATHS option or in the
short-hand version of the command. These are typically hard-coded
guesses.
On Darwin or systems supporting OS X Frameworks, the cmake variable
CMAKE_FIND_FRAMEWORK can be set to empty or one of the following:

"ONLY" - Only try to find frameworks.
"NEVER" - Never try to find frameworks.
On Darwin or systems supporting OS X Application Bundles, the cmake
variable CMAKE_FIND_APPBUNDLE can be set to empty or one of the
following:
"FIRST" - Try to find application bundles before standard
programs. This is the default on Darwin.
"LAST" - Try to find application bundles after standard
programs.
"ONLY" - Only try to find application bundles.
"NEVER" - Never try to find application bundles.
The CMake variable CMAKE_FIND_ROOT_PATH specifies one or more
directories to be prepended to all other search directories. This
effectively "re-roots" the entire search under given locations. By
default it is empty. It is especially useful when cross-compiling to
point to the root directory of the target environment and CMake will
search there too. By default at first the directories listed in
CMAKE_FIND_ROOT_PATH and then the non-rooted directories will be
searched. The default behavior can be adjusted by setting
CMAKE_FIND_ROOT_PATH_MODE_INCLUDE. This behavior can be manually
overridden on a per-call basis. By using CMAKE_FIND_ROOT_PATH_BOTH
the search order will be as described above. If
NO_CMAKE_FIND_ROOT_PATH is used then CMAKE_FIND_ROOT_PATH will not be
used. If ONLY_CMAKE_FIND_ROOT_PATH is used then only the re-rooted
directories will be searched.
The default search order is designed to be most-specific to
least-specific for common use cases. Projects may override the order
by simply calling the command multiple times and using the NO_*
options:
find_path(<VAR> NAMES name PATHS paths... NO_DEFAULT_PATH)
find_path(<VAR> NAMES name)
Once one of the calls succeeds the result variable will be set and
stored in the cache so that no call will search again.
When searching for frameworks, if the file is specified as A/b.h, then
the framework search will look for A.framework/Headers/b.h. If that
is found the path will be set to the path to the framework. CMake
will convert this to the correct -F option to include the file.
find_program
Find an executable program.
find_program(<VAR> name1 [path1 path2 ...])
This is the short-hand signature for the command that is sufficient in
many cases. It is the same as find_program(<VAR> name1 [PATHS path1
path2 ...])
find_program(
<VAR>
name | NAMES name1 [name2 ...]
[HINTS path1 [path2 ... ENV var]]
[PATHS path1 [path2 ... ENV var]]
[PATH_SUFFIXES suffix1 [suffix2 ...]]
[DOC "cache documentation string"]
[NO_DEFAULT_PATH]
[NO_CMAKE_ENVIRONMENT_PATH]
[NO_CMAKE_PATH]
[NO_SYSTEM_ENVIRONMENT_PATH]
[NO_CMAKE_SYSTEM_PATH]
[CMAKE_FIND_ROOT_PATH_BOTH |
ONLY_CMAKE_FIND_ROOT_PATH |
NO_CMAKE_FIND_ROOT_PATH]
)
This command is used to find a program. A cache entry named by <VAR>
is created to store the result of this command. If the program is
found the result is stored in the variable and the search will not be
repeated unless the variable is cleared. If nothing is found, the
result will be <VAR>-NOTFOUND, and the search will be attempted again
the next time find_program is invoked with the same variable. The
name of the program that is searched for is specified by the names
listed after the NAMES argument. Additional search locations can be
specified after the PATHS argument. If ENV var is found in the HINTS
or PATHS section the environment variable var will be read and
converted from a system environment variable to a cmake style list of
paths. For example ENV PATH would be a way to list the system path
variable. The argument after DOC will be used for the documentation
string in the cache. PATH_SUFFIXES specifies additional
subdirectories to check below each search path.
If NO_DEFAULT_PATH is specified, then no additional paths are added to
the search. If NO_DEFAULT_PATH is not specified, the search process
is as follows:
1. Search paths specified in cmake-specific cache variables. These
are intended to be used on the command line with a -DVAR=value. This
can be skipped if NO_CMAKE_PATH is passed.

CMAKE_PROGRAM_PATH
CMAKE_APPBUNDLE_PATH
2. Search paths specified in cmake-specific environment variables.
These are intended to be set in the user's shell configuration. This
can be skipped if NO_CMAKE_ENVIRONMENT_PATH is passed.
<prefix>/[s]bin for each <prefix> in CMAKE_PREFIX_PATH
CMAKE_PROGRAM_PATH
CMAKE_APPBUNDLE_PATH
3. Search the paths specified by the HINTS option. These should be
paths computed by system introspection, such as a hint provided by the
location of another item already found. Hard-coded guesses should be

passed.
<prefix>/[s]bin for each <prefix> in CMAKE_SYSTEM_PREFIX_PATH
CMAKE_SYSTEM_PROGRAM_PATH

fltk_wrap_ui
Create FLTK user interfaces Wrappers.
fltk_wrap_ui(resultingLibraryName source1
source2 ... sourceN )
Produce .h and .cxx files for all the .fl and .fld files listed. The
resulting .h and .cxx files will be added to a variable named
resultingLibraryName_FLTK_UI_SRCS which should be added to your
library.
foreach
Evaluate a group of commands for each value in a list.
foreach(loop_var arg1 arg2 ...)
COMMAND1(ARGS ...)
COMMAND2(ARGS ...)
...
endforeach(loop_var)
All commands between foreach and the matching endforeach are recorded
without being invoked. Once the endforeach is evaluated, the recorded
list of commands is invoked once for each argument listed in the
original foreach command. Before each iteration of the loop
"${loop_var}" will be set as a variable with the current value in the
list.
foreach(loop_var RANGE total)
foreach(loop_var RANGE start stop [step])
Foreach can also iterate over a generated range of numbers. There are
three types of this iteration:
* When specifying single number, the range will have elements 0 to
"total".
* When specifying two numbers, the range will have elements from the
first number to the second number.
* The third optional number is the increment used to iterate from the
first number to the second number.
foreach(loop_var IN [LISTS [list1 [...]]]
[ITEMS [item1 [...]]])
Iterates over a precise list of items. The LISTS option names
list-valued variables to be traversed, including empty elements (an
empty string is a zero-length list). The ITEMS option ends argument
parsing and includes all arguments following it in the iteration.
function
Start recording a function for later invocation as a command.
function(<name> [arg1 [arg2 [arg3 ...]]])
COMMAND1(ARGS ...)
COMMAND2(ARGS ...)
...
endfunction(<name>)
Define a function named <name> that takes arguments named arg1 arg2
arg3 (...). Commands listed after function, but before the matching
endfunction, are not invoked until the function is invoked. When it
is invoked, the commands recorded in the function are first modified
by replacing formal parameters (${arg1}) with the arguments passed,
and then invoked as normal commands. In addition to referencing the
formal parameters you can reference the variable ARGC which will be
set to the number of arguments passed into the function as well as
ARGV0 ARGV1 ARGV2 ... which will have the actual values of the
arguments passed in. This facilitates creating functions with
optional arguments. Additionally ARGV holds the list of all arguments
given to the function and ARGN holds the list of argument past the
last expected argument.
See the cmake_policy() command documentation for the behavior of
policies inside functions.
get_cmake_property
Get a property of the CMake instance.
get_cmake_property(VAR property)
Get a property from the CMake instance. The value of the property is
stored in the variable VAR. If the property is not found, CMake will
report an error. Some supported properties include: VARIABLES,
CACHE_VARIABLES, COMMANDS, MACROS, and COMPONENTS.
get_directory_property
Get a property of DIRECTORY scope.
get_directory_property(<variable> [DIRECTORY <dir>] <prop-name>)
Store a property of directory scope in the named variable. If the
property is not defined the empty-string is returned. The DIRECTORY
argument specifies another directory from which to retrieve the
property value. The specified directory must have already been
traversed by CMake.
get_directory_property(<variable> [DIRECTORY <dir>]
DEFINITION <var-name>)
Get a variable definition from a directory. This form is useful to
get a variable definition from another directory.
get_filename_component
Get a specific component of a full filename.
get_filename_component(VarName FileName
PATH|ABSOLUTE|NAME|EXT|NAME_WE|REALPATH
[CACHE])
Set VarName to be the path (PATH), file name (NAME), file extension
(EXT), file name without extension (NAME_WE) of FileName, the full
path (ABSOLUTE), or the full path with all symlinks resolved
(REALPATH). Note that the path is converted to Unix slashes format
and has no trailing slashes. The longest file extension is always
considered. If the optional CACHE argument is specified, the result
variable is added to the cache.
get_filename_component(VarName FileName
PROGRAM [PROGRAM_ARGS ArgVar]
[CACHE])
The program in FileName will be found in the system search path or
left as a full path. If PROGRAM_ARGS is present with PROGRAM, then
any command-line arguments present in the FileName string are split
from the program name and stored in ArgVar. This is used to separate
a program name from its arguments in a command line string.
get_property
Get a property.
get_property(<variable>
<GLOBAL |
DIRECTORY [dir] |
TARGET <target> |
SOURCE <source> |
TEST <test> |
CACHE <entry> |
VARIABLE>
PROPERTY <name>
[SET | DEFINED | BRIEF_DOCS | FULL_DOCS])
Get one property from one object in a scope. The first argument
specifies the variable in which to store the result. The second
argument determines the scope from which to get the property. It must
be one of the following:
GLOBAL scope is unique and does not accept a name.
DIRECTORY scope defaults to the current directory but another
directory (already processed by CMake) may be named by full or
relative path.
TARGET scope must name one existing target.
SOURCE scope must name one source file.
TEST scope must name one existing test.
CACHE scope must name one cache entry.
VARIABLE scope is unique and does not accept a name.
The required PROPERTY option is immediately followed by the name of
the property to get. If the property is not set an empty value is
returned. If the SET option is given the variable is set to a boolean
value indicating whether the property has been set. If the DEFINED
option is given the variable is set to a boolean value indicating
whether the property has been defined such as with define_property.
If BRIEF_DOCS or FULL_DOCS is given then the variable is set to a
string containing documentation for the requested property. If
documentation is requested for a property that has not been defined
NOTFOUND is returned.
get_source_file_property
Get a property for a source file.
get_source_file_property(VAR file property)
Get a property from a source file. The value of the property is
stored in the variable VAR. If the property is not found, VAR will be
set to "NOTFOUND". Use set_source_files_properties to set property
values. Source file properties usually control how the file is built.
One property that is always there is LOCATION
get_target_property
Get a property from a target.
get_target_property(VAR target property)
Get a property from a target. The value of the property is stored in
the variable VAR. If the property is not found, VAR will be set to
"NOTFOUND". Use set_target_properties to set property values.
Properties are usually used to control how a target is built, but some
query the target instead. This command can get properties for any
target so far created. The targets do not need to be in the current
CMakeLists.txt file.
get_test_property
Get a property of the test.
get_test_property(test VAR property)
Get a property from the Test. The value of the property is stored in
the variable VAR. If the property is not found, CMake will report an
error. For a list of standard properties you can type cmake
--help-property-list
if
Conditionally execute a group of commands.
if(expression)
# then section.
COMMAND1(ARGS ...)
COMMAND2(ARGS ...)
...
elseif(expression2)
# elseif section.
COMMAND1(ARGS ...)
COMMAND2(ARGS ...)
...
else(expression)
# else section.
COMMAND1(ARGS ...)
COMMAND2(ARGS ...)
...
endif(expression)
Evaluates the given expression. If the result is true, the commands
in the THEN section are invoked. Otherwise, the commands in the else
section are invoked. The elseif and else sections are optional. You
may have multiple elseif clauses. Note that the expression in the
else and endif clause is optional. Long expressions can be used and
there is a traditional order of precedence. Parenthetical expressions
are evaluated first followed by unary operators such as EXISTS,
COMMAND, and DEFINED. Then any EQUAL, LESS, GREATER, STRLESS,
STRGREATER, STREQUAL, MATCHES will be evaluated. Then NOT operators
and finally AND, OR operators will be evaluated. Possible expressions
are:
if(<constant>)
True if the constant is 1, ON, YES, TRUE, Y, or a non-zero number.
False if the constant is 0, OFF, NO, FALSE, N, IGNORE, "", or ends in
the suffix '-NOTFOUND'. Named boolean constants are case-insensitive.
if(<variable>)
True if the variable's value is not a false constant.
if(NOT <expression>)
True if the expression is not true.
if(<expr1> AND <expr2>)
True if both expressions would be considered true individually.
if(<expr1> OR <expr2>)
True if either expression would be considered true individually.
if(COMMAND command-name)
True if the given name is a command, macro or function that can be
invoked.
if(POLICY policy-id)
True if the given name is an existing policy (of the form CMP<NNNN>).
if(TARGET target-name)
True if the given name is an existing target, built or imported.
if(EXISTS file-name)
if(EXISTS directory-name)
True if the named file or directory exists. Behavior is well-defined
only for full paths.
if(file1 IS_NEWER_THAN file2)
True if file1 is newer than file2 or if one of the two files doesn't
exist. Behavior is well-defined only for full paths.
if(IS_DIRECTORY directory-name)
True if the given name is a directory. Behavior is well-defined only
for full paths.
if(IS_ABSOLUTE path)
True if the given path is an absolute path.
if(variable MATCHES regex)
if(string MATCHES regex)
True if the given string or variable's value matches the given regular
expression.
if(variable LESS number)
if(string LESS number)
if(variable GREATER number)
if(string GREATER number)
if(variable EQUAL number)
if(string EQUAL number)
True if the given string or variable's value is a valid number and the
inequality or equality is true.
if(variable STRLESS string)
if(string STRLESS string)
if(variable STRGREATER string)
if(string STRGREATER string)
if(variable STREQUAL string)
if(string STREQUAL string)
True if the given string or variable's value is lexicographically less
(or greater, or equal) than the string or variable on the right.
if(version1 VERSION_LESS version2)
if(version1 VERSION_EQUAL version2)
if(version1 VERSION_GREATER version2)
Component-wise integer version number comparison (version format is
major[.minor[.patch[.tweak]]]).
if(DEFINED variable)
True if the given variable is defined. It does not matter if the
variable is true or false just if it has been set.
if((expression) AND (expression OR (expression)))
The expressions inside the parenthesis are evaluated first and then
the remaining expression is evaluated as in the previous examples.
Where there are nested parenthesis the innermost are evaluated as part
of evaluating the expression that contains them.
The if statement was written fairly early in CMake's history and it
has some convenience features that are worth covering. The if
statement reduces operations until there is a single remaining value,
at that point if the case insensitive value is: ON, 1, YES, TRUE, Y it
returns true, if it is OFF, 0, NO, FALSE, N, NOTFOUND, *-NOTFOUND,
IGNORE it will return false.
This is fairly reasonable. The convenience feature that sometimes
throws new authors is how CMake handles values that do not match the
true or false list. Those values are treated as variables and are
dereferenced even though they do not have the required ${} syntax.
This means that if you write
if (boobah)
CMake will treat it as if you wrote
if (${boobah})
likewise if you write
if (fubar AND sol)
CMake will conveniently treat it as
if ("${fubar}" AND "${sol}")
The later is really the correct way to write it, but the former will
work as well. Only some operations in the if statement have this
special handling of arguments. The specific details follow:
1) The left hand argument to MATCHES is first checked to see if it is
a defined variable, if so the variable's value is used, otherwise the
original value is used.
2) If the left hand argument to MATCHES is missing it returns false
without error
3) Both left and right hand arguments to LESS GREATER EQUAL are
independently tested to see if they are defined variables, if so their
defined values are used otherwise the original value is used.
4) Both left and right hand arguments to STRLESS STREQUAL STRGREATER
are independently tested to see if they are defined variables, if so
their defined values are used otherwise the original value is used.
5) Both left and right hand argumemnts to VERSION_LESS VERSION_EQUAL
VERSION_GREATER are independently tested to see if they are defined
variables, if so their defined values are used otherwise the original
value is used.
6) The right hand argument to NOT is tested to see if it is a boolean
constant, if so the value is used, otherwise it is assumed to be a
variable and it is dereferenced.
7) The left and right hand arguments to AND OR are independently
tested to see if they are boolean constants, if so they are used as
such, otherwise they are assumed to be variables and are dereferenced.
include
Read CMake listfile code from the given file.
include(<file|module> [OPTIONAL] [RESULT_VARIABLE <VAR>]
[NO_POLICY_SCOPE])
Reads CMake listfile code from the given file. Commands in the file
are processed immediately as if they were written in place of the
include command. If OPTIONAL is present, then no error is raised if
the file does not exist. If RESULT_VARIABLE is given the variable
will be set to the full filename which has been included or NOTFOUND
if it failed.
If a module is specified instead of a file, the file with name
<modulename>.cmake is searched in the CMAKE_MODULE_PATH.
See the cmake_policy() command documentation for discussion of the
NO_POLICY_SCOPE option.
include_directories
Add include directories to the build.
include_directories([AFTER|BEFORE] [SYSTEM] dir1 dir2 ...)
Add the given directories to those searched by the compiler for
include files. By default the directories are appended onto the
current list of directories. This default behavior can be changed by
setting CMAKE_include_directories_BEFORE to ON. By using BEFORE or
AFTER you can select between appending and prepending, independent
from the default. If the SYSTEM option is given the compiler will be
told that the directories are meant as system include directories on
some platforms.
include_external_msproject
Include an external Microsoft project file in a workspace.
include_external_msproject(projectname location
dep1 dep2 ...)
Includes an external Microsoft project in the generated workspace
file. Currently does nothing on UNIX. This will create a target
named INCLUDE_EXTERNAL_MSPROJECT_[projectname]. This can be used in
the add_dependencies command to make things depend on the external
project.
include_regular_expression
Set the regular expression used for dependency checking.
include_regular_expression(regex_match [regex_complain])
Set the regular expressions used in dependency checking. Only files
matching regex_match will be traced as dependencies. Only files
matching regex_complain will generate warnings if they cannot be found
(standard header paths are not searched). The defaults are:
regex_match = "^.*$" (match everything)
regex_complain = "^$" (match empty string only)
install
Specify rules to run at install time.
This command generates installation rules for a project. Rules
specified by calls to this command within a source directory are
executed in order during installation. The order across directories
is not defined.
There are multiple signatures for this command. Some of them define
installation properties for files and targets. Properties common to
multiple signatures are covered here but they are valid only for
signatures that specify them.
DESTINATION arguments specify the directory on disk to which a file
will be installed. If a full path (with a leading slash or drive
letter) is given it is used directly. If a relative path is given it
is interpreted relative to the value of CMAKE_INSTALL_PREFIX.
PERMISSIONS arguments specify permissions for installed files. Valid
permissions are OWNER_READ, OWNER_WRITE, OWNER_EXECUTE, GROUP_READ,
GROUP_WRITE, GROUP_EXECUTE, WORLD_READ, WORLD_WRITE, WORLD_EXECUTE,
SETUID, and SETGID. Permissions that do not make sense on certain
platforms are ignored on those platforms.
The CONFIGURATIONS argument specifies a list of build configurations
for which the install rule applies (Debug, Release, etc.).
The COMPONENT argument specifies an installation component name with
which the install rule is associated, such as "runtime" or
"development". During component-specific installation only install
rules associated with the given component name will be executed.
During a full installation all components are installed.
The RENAME argument specifies a name for an installed file that may be
different from the original file. Renaming is allowed only when a
single file is installed by the command.
The OPTIONAL argument specifies that it is not an error if the file to
be installed does not exist.
The TARGETS signature:
install(TARGETS targets... [EXPORT <export-name>]
[[ARCHIVE|LIBRARY|RUNTIME|FRAMEWORK|BUNDLE|
PRIVATE_HEADER|PUBLIC_HEADER|RESOURCE]
[DESTINATION <dir>]
[PERMISSIONS permissions...]
[CONFIGURATIONS [Debug|Release|...]]
[COMPONENT <component>]
[OPTIONAL] [NAMELINK_ONLY|NAMELINK_SKIP]
] [...])
The TARGETS form specifies rules for installing targets from a
project. There are five kinds of target files that may be installed:
ARCHIVE, LIBRARY, RUNTIME, FRAMEWORK, and BUNDLE. Executables are
treated as RUNTIME targets, except that those marked with the
MACOSX_BUNDLE property are treated as BUNDLE targets on OS X. Static
libraries are always treated as ARCHIVE targets. Module libraries are
always treated as LIBRARY targets. For non-DLL platforms shared
libraries are treated as LIBRARY targets, except that those marked
with the FRAMEWORK property are treated as FRAMEWORK targets on OS X.
For DLL platforms the DLL part of a shared library is treated as a
RUNTIME target and the corresponding import library is treated as an
ARCHIVE target. All Windows-based systems including Cygwin are DLL
platforms. The ARCHIVE, LIBRARY, RUNTIME, and FRAMEWORK arguments
change the type of target to which the subsequent properties apply.
If none is given the installation properties apply to all target
types. If only one is given then only targets of that type will be
installed (which can be used to install just a DLL or just an import
library).
The PRIVATE_HEADER, PUBLIC_HEADER, and RESOURCE arguments cause
subsequent properties to be applied to installing a FRAMEWORK shared
library target's associated files on non-Apple platforms. Rules
defined by these arguments are ignored on Apple platforms because the
associated files are installed into the appropriate locations inside
the framework folder. See documentation of the PRIVATE_HEADER,
PUBLIC_HEADER, and RESOURCE target properties for details.
Either NAMELINK_ONLY or NAMELINK_SKIP may be specified as a LIBRARY
option. On some platforms a versioned shared library has a symbolic
link such as
lib<name>.so -> lib<name>.so.1
where "lib<name>.so.1" is the soname of the library and "lib<name>.so"
is a "namelink" allowing linkers to find the library when given
"-l<name>". The NAMELINK_ONLY option causes installation of only the
namelink when a library target is installed. The NAMELINK_SKIP option
causes installation of library files other than the namelink when a
library target is installed. When neither option is given both
portions are installed. On platforms where versioned shared libraries
do not have namelinks or when a library is not versioned the
NAMELINK_SKIP option installs the library and the NAMELINK_ONLY option
installs nothing. See the VERSION and SOVERSION target properties for
details on creating versioned shared libraries.
One or more groups of properties may be specified in a single call to
the TARGETS form of this command. A target may be installed more than
once to different locations. Consider hypothetical targets "myExe",
"mySharedLib", and "myStaticLib". The code
install(TARGETS myExe mySharedLib myStaticLib
RUNTIME DESTINATION bin
LIBRARY DESTINATION lib
ARCHIVE DESTINATION lib/static)
install(TARGETS mySharedLib DESTINATION /some/full/path)
will install myExe to <prefix>/bin and myStaticLib to
<prefix>/lib/static. On non-DLL platforms mySharedLib will be
installed to <prefix>/lib and /some/full/path. On DLL platforms the
mySharedLib DLL will be installed to <prefix>/bin and /some/full/path
and its import library will be installed to <prefix>/lib/static and
/some/full/path. On non-DLL platforms mySharedLib will be installed
to <prefix>/lib and /some/full/path.
The EXPORT option associates the installed target files with an export
called <export-name>. It must appear before any RUNTIME, LIBRARY, or
ARCHIVE options. See documentation of the install(EXPORT ...)
signature below for details.
Installing a target with EXCLUDE_FROM_ALL set to true has undefined
behavior.
The FILES signature:
install(FILES files... DESTINATION <dir>
[PERMISSIONS permissions...]
[CONFIGURATIONS [Debug|Release|...]]
[COMPONENT <component>]
[RENAME <name>] [OPTIONAL])
The FILES form specifies rules for installing files for a project.
File names given as relative paths are interpreted with respect to the
current source directory. Files installed by this form are by default
given permissions OWNER_WRITE, OWNER_READ, GROUP_READ, and WORLD_READ
if no PERMISSIONS argument is given.
The PROGRAMS signature:
install(PROGRAMS files... DESTINATION <dir>
[PERMISSIONS permissions...]
[CONFIGURATIONS [Debug|Release|...]]
[COMPONENT <component>]
[RENAME <name>] [OPTIONAL])
The PROGRAMS form is identical to the FILES form except that the
default permissions for the installed file also include OWNER_EXECUTE,
GROUP_EXECUTE, and WORLD_EXECUTE. This form is intended to install
programs that are not targets, such as shell scripts. Use the TARGETS
form to install targets built within the project.
The DIRECTORY signature:
install(DIRECTORY dirs... DESTINATION <dir>
[FILE_PERMISSIONS permissions...]
[DIRECTORY_PERMISSIONS permissions...]
[USE_SOURCE_PERMISSIONS] [OPTIONAL]
[CONFIGURATIONS [Debug|Release|...]]
[COMPONENT <component>] [FILES_MATCHING]
[[PATTERN <pattern> | REGEX <regex>]
[EXCLUDE] [PERMISSIONS permissions...]] [...])
The DIRECTORY form installs contents of one or more directories to a
given destination. The directory structure is copied verbatim to the
destination. The last component of each directory name is appended to
the destination directory but a trailing slash may be used to avoid
this because it leaves the last component empty. Directory names
given as relative paths are interpreted with respect to the current
source directory. If no input directory names are given the
destination directory will be created but nothing will be installed
into it. The FILE_PERMISSIONS and DIRECTORY_PERMISSIONS options
specify permissions given to files and directories in the destination.
If USE_SOURCE_PERMISSIONS is specified and FILE_PERMISSIONS is not,
file permissions will be copied from the source directory structure.
If no permissions are specified files will be given the default
permissions specified in the FILES form of the command, and the
directories will be given the default permissions specified in the
PROGRAMS form of the command.
Installation of directories may be controlled with fine granularity
using the PATTERN or REGEX options. These "match" options specify a
globbing pattern or regular expression to match directories or files
encountered within input directories. They may be used to apply
certain options (see below) to a subset of the files and directories
encountered. The full path to each input file or directory (with
forward slashes) is matched against the expression. A PATTERN will
match only complete file names: the portion of the full path matching
the pattern must occur at the end of the file name and be preceded by
a slash. A REGEX will match any portion of the full path but it may
use '/' and '$' to simulate the PATTERN behavior. By default all
files and directories are installed whether or not they are matched.
The FILES_MATCHING option may be given before the first match option
to disable installation of files (but not directories) not matched by
any expression. For example, the code
install(DIRECTORY src/ DESTINATION include/myproj
FILES_MATCHING PATTERN "*.h")
will extract and install header files from a source tree.
Some options may follow a PATTERN or REGEX expression and are applied
only to files or directories matching them. The EXCLUDE option will
skip the matched file or directory. The PERMISSIONS option overrides
the permissions setting for the matched file or directory. For
example the code
install(DIRECTORY icons scripts/ DESTINATION share/myproj
PATTERN "CVS" EXCLUDE
PATTERN "scripts/*"
PERMISSIONS OWNER_EXECUTE OWNER_WRITE OWNER_READ
GROUP_EXECUTE GROUP_READ)
will install the icons directory to share/myproj/icons and the scripts
directory to share/myproj. The icons will get default file
permissions, the scripts will be given specific permissions, and any
CVS directories will be excluded.
The SCRIPT and CODE signature:
install([[SCRIPT <file>] [CODE <code>]] [...])
The SCRIPT form will invoke the given CMake script files during
installation. If the script file name is a relative path it will be
interpreted with respect to the current source directory. The CODE
form will invoke the given CMake code during installation. Code is
specified as a single argument inside a double-quoted string. For
example, the code
install(CODE "MESSAGE(\"Sample install message.\")")
will print a message during installation.
The EXPORT signature:
install(EXPORT <export-name> DESTINATION <dir>
[NAMESPACE <namespace>] [FILE <name>.cmake]
[PERMISSIONS permissions...]
[CONFIGURATIONS [Debug|Release|...]]
[COMPONENT <component>])
The EXPORT form generates and installs a CMake file containing code to
import targets from the installation tree into another project.
Target installations are associated with the export <export-name>
using the EXPORT option of the install(TARGETS ...) signature
documented above. The NAMESPACE option will prepend <namespace> to
the target names as they are written to the import file. By default
the generated file will be called <export-name>.cmake but the FILE
option may be used to specify a different name. The value given to
the FILE option must be a file name with the ".cmake" extension. If a
CONFIGURATIONS option is given then the file will only be installed
when one of the named configurations is installed. Additionally, the
generated import file will reference only the matching target
configurations. If a COMPONENT option is specified that does not
match that given to the targets associated with <export-name> the
behavior is undefined. If a library target is included in the export
but a target to which it links is not included the behavior is
unspecified.
The EXPORT form is useful to help outside projects use targets built
and installed by the current project. For example, the code
install(TARGETS myexe EXPORT myproj DESTINATION bin)
install(EXPORT myproj NAMESPACE mp_ DESTINATION lib/myproj)
will install the executable myexe to <prefix>/bin and code to import
it in the file "<prefix>/lib/myproj/myproj.cmake". An outside project
may load this file with the include command and reference the myexe
executable from the installation tree using the imported target name
mp_myexe as if the target were built in its own tree.
NOTE: This command supercedes the INSTALL_TARGETS command and the
target properties PRE_INSTALL_SCRIPT and POST_INSTALL_SCRIPT. It also
replaces the FILES forms of the INSTALL_FILES and INSTALL_PROGRAMS
commands. The processing order of these install rules relative to
those generated by INSTALL_TARGETS, INSTALL_FILES, and
INSTALL_PROGRAMS commands is not defined.
link_directories
Specify directories in which the linker will look for libraries.
link_directories(directory1 directory2 ...)
Specify the paths in which the linker should search for libraries.
The command will apply only to targets created after it is called.
For historical reasons, relative paths given to this command are
passed to the linker unchanged (unlike many CMake commands which
interpret them relative to the current source directory).
list
List operations.
list(LENGTH <list> <output variable>)
list(GET <list> <element index> [<element index> ...]
<output variable>)
list(APPEND <list> <element> [<element> ...])
list(FIND <list> <value> <output variable>)
list(INSERT <list> <element_index> <element> [<element> ...])
list(REMOVE_ITEM <list> <value> [<value> ...])
list(REMOVE_AT <list> <index> [<index> ...])
list(REMOVE_DUPLICATES <list>)
list(REVERSE <list>)
list(SORT <list>)
LENGTH will return a given list's length.
GET will return list of elements specified by indices from the list.
APPEND will append elements to the list.
FIND will return the index of the element specified in the list or -1
if it wasn't found.
INSERT will insert elements to the list to the specified location.
REMOVE_AT and REMOVE_ITEM will remove items from the list. The
difference is that REMOVE_ITEM will remove the given items, while
REMOVE_AT will remove the items at the given indices.
REMOVE_DUPLICATES will remove duplicated items in the list.
REVERSE reverses the contents of the list in-place.
SORT sorts the list in-place alphabetically.
NOTES: A list in cmake is a ; separated group of strings. To create a
list the set command can be used. For example, set(var a b c d e)
creates a list with a;b;c;d;e, and set(var "a b c d e") creates a
string or a list with one item in it.
When specifying index values, if <element index> is 0 or greater, it
is indexed from the beginning of the list, with 0 representing the
first list element. If <element index> is -1 or lesser, it is indexed
from the end of the list, with -1 representing the last list element.
Be careful when counting with negative indices: they do not start from
0. -0 is equivalent to 0, the first list element.
load_cache
Load in the values from another project's CMake cache.
load_cache(pathToCacheFile READ_WITH_PREFIX
prefix entry1...)
Read the cache and store the requested entries in variables with their
name prefixed with the given prefix. This only reads the values, and
does not create entries in the local project's cache.
load_cache(pathToCacheFile [EXCLUDE entry1...]
[INCLUDE_INTERNALS entry1...])
Load in the values from another cache and store them in the local
project's cache as internal entries. This is useful for a project
that depends on another project built in a different tree. EXCLUDE
option can be used to provide a list of entries to be excluded.
INCLUDE_INTERNALS can be used to provide a list of internal entries to
be included. Normally, no internal entries are brought in. Use of
this form of the command is strongly discouraged, but it is provided
for backward compatibility.
load_command
Load a command into a running CMake.
load_command(COMMAND_NAME <loc1> [loc2 ...])
The given locations are searched for a library whose name is
cmCOMMAND_NAME. If found, it is loaded as a module and the command is
added to the set of available CMake commands. Usually, TRY_COMPILE is
used before this command to compile the module. If the command is
successfully loaded a variable named
CMAKE_LOADED_COMMAND_<COMMAND_NAME>
will be set to the full path of the module that was loaded. Otherwise
the variable will not be set.
macro
Start recording a macro for later invocation as a command.
macro(<name> [arg1 [arg2 [arg3 ...]]])
COMMAND1(ARGS ...)
COMMAND2(ARGS ...)
...
endmacro(<name>)
Define a macro named <name> that takes arguments named arg1 arg2 arg3
(...). Commands listed after macro, but before the matching endmacro,
are not invoked until the macro is invoked. When it is invoked, the
commands recorded in the macro are first modified by replacing formal
parameters (${arg1}) with the arguments passed, and then invoked as
normal commands. In addition to referencing the formal parameters you
can reference the values ${ARGC} which will be set to the number of
arguments passed into the function as well as ${ARGV0} ${ARGV1}
${ARGV2} ... which will have the actual values of the arguments
passed in. This facilitates creating macros with optional arguments.
Additionally ${ARGV} holds the list of all arguments given to the
macro and ${ARGN} holds the list of argument past the last expected
argument. Note that the parameters to a macro and values such as ARGN
are not variables in the usual CMake sense. They are string
replacements much like the c preprocessor would do with a macro. If
you want true CMake variables you should look at the function command.
See the cmake_policy() command documentation for the behavior of
policies inside macros.
mark_as_advanced
Mark cmake cached variables as advanced.
mark_as_advanced([CLEAR|FORCE] VAR VAR2 VAR...)
Mark the named cached variables as advanced. An advanced variable
will not be displayed in any of the cmake GUIs unless the show
advanced option is on. If CLEAR is the first argument advanced
variables are changed back to unadvanced. If FORCE is the first
argument, then the variable is made advanced. If neither FORCE nor
CLEAR is specified, new values will be marked as advanced, but if the
variable already has an advanced/non-advanced state, it will not be
changed.
It does nothing in script mode.
math
Mathematical expressions.
math(EXPR <output variable> <math expression>)
EXPR evaluates mathematical expression and return result in the output
variable. Example mathematical expression is '5 * ( 10 + 13 )'.
Supported operators are + - * / % | & ^ ~ << >> * / %. They have the
same meaning as they do in c code.
message
Display a message to the user.
message([STATUS|WARNING|AUTHOR_WARNING|FATAL_ERROR|SEND_ERROR]
"message to display" ...)
The optional keyword determines the type of message:
(none) = Important information
STATUS = Incidental information
WARNING = CMake Warning, continue processing
AUTHOR_WARNING = CMake Warning (dev), continue processing
SEND_ERROR = CMake Error, continue but skip generation
FATAL_ERROR = CMake Error, stop all processing
The CMake command-line tool displays STATUS messages on stdout and all
other message types on stderr. The CMake GUI displays all messages in
its log area. The interactive dialogs (ccmake and CMakeSetup) show
STATUS messages one at a time on a status line and other messages in
interactive pop-up boxes.
CMake Warning and Error message text displays using a simple markup
language. Non-indented text is formatted in line-wrapped paragraphs
delimited by newlines. Indented text is considered pre-formatted.
option
Provides an option that the user can optionally select.
option(<option_variable> "help string describing option"
[initial value])
Provide an option for the user to select as ON or OFF. If no initial
value is provided, OFF is used.
output_required_files
Output a list of required source files for a specified source file.
output_required_files(srcfile outputfile)
Outputs a list of all the source files that are required by the
specified srcfile. This list is written into outputfile. This is
similar to writing out the dependencies for srcfile except that it
jumps from .h files into .cxx, .c and .cpp files if possible.
project
Set a name for the entire project.
project(<projectname> [languageName1 languageName2 ... ] )
Sets the name of the project. Additionally this sets the variables
<projectName>_BINARY_DIR and <projectName>_SOURCE_DIR to the
respective values.
Optionally you can specify which languages your project supports.
Example languages are CXX (i.e. C++), C, Fortran, etc. By default C
and CXX are enabled. E.g. if you do not have a C++ compiler, you can
disable the check for it by explicitely listing the languages you want
to support, e.g. C. By using the special language "NONE" all checks
for any language can be disabled.
qt_wrap_cpp
Create Qt Wrappers.
qt_wrap_cpp(resultingLibraryName DestName
SourceLists ...)
Produce moc files for all the .h files listed in the SourceLists. The
moc files will be added to the library using the DestName source list.
qt_wrap_ui
Create Qt user interfaces Wrappers.
qt_wrap_ui(resultingLibraryName HeadersDestName
SourcesDestName SourceLists ...)
Produce .h and .cxx files for all the .ui files listed in the
SourceLists. The .h files will be added to the library using the
HeadersDestNamesource list. The .cxx files will be added to the
library using the SourcesDestNamesource list.
remove_definitions
Removes -D define flags added by add_definitions.
remove_definitions(-DFOO -DBAR ...)
Removes flags (added by add_definitions) from the compiler command
line for sources in the current directory and below.
return
Return from a file, directory or function.
return()
Returns from a file, directory or function. When this command is
encountered in an included file (via include() or find_package()), it
causes processing of the current file to stop and control is returned
to the including file. If it is encountered in a file which is not
included by another file, e.g. a CMakeLists.txt, control is returned
to the parent directory if there is one. If return is called in a
function, control is returned to the caller of the function. Note
that a macro is not a function and does not handle return like a
function does.
separate_arguments
Parse space-separated arguments into a semicolon-separated list.
separate_arguments(<var> <UNIX|WINDOWS>_COMMAND "<args>")
Parses a unix- or windows-style command-line string "<args>" and
stores a semicolon-separated list of the arguments in <var>. The
entire command line must be given in one "<args>" argument.
The UNIX_COMMAND mode separates arguments by unquoted whitespace. It
recognizes both single-quote and double-quote pairs. A backslash
escapes the next literal character (\" is "); there are no special
escapes (\n is just n).
The WINDOWS_COMMAND mode parses a windows command-line using the same
syntax the runtime library uses to construct argv at startup. It
separates arguments by whitespace that is not double-quoted.
Backslashes are literal unless they precede double-quotes. See the
MSDN article "Parsing C Command-Line Arguments" for details.
separate_arguments(VARIABLE)
Convert the value of VARIABLE to a semi-colon separated list. All
spaces are replaced with ';'. This helps with generating command
lines.
set
Set a CMAKE variable to a given value.
set(<variable> <value>
[[CACHE <type> <docstring> [FORCE]] | PARENT_SCOPE])
Within CMake sets <variable> to the value <value>. <value> is
expanded before <variable> is set to it. If CACHE is present, then
the <variable> is put in the cache. <type> and <docstring> are then
required. <type> is used by the CMake GUI to choose a widget with
which the user sets a value. The value for <type> may be one of
FILEPATH = File chooser dialog.
PATH = Directory chooser dialog.
STRING = Arbitrary string.
BOOL = Boolean ON/OFF checkbox.
INTERNAL = No GUI entry (used for persistent variables).
If <type> is INTERNAL, then the <value> is always written into the
cache, replacing any values existing in the cache. If it is not a
cache variable, then this always writes into the current makefile.
The FORCE option will overwrite the cache value removing any changes
by the user.
If PARENT_SCOPE is present, the variable will be set in the scope
above the current scope. Each new directory or function creates a new
scope. This command will set the value of a variable into the parent
directory or calling function (whichever is applicable to the case at
hand).
If <value> is not specified then the variable is removed instead of
set. See also: the unset() command.
set(<variable> <value1> ... <valueN>)
In this case <variable> is set to a semicolon separated list of
values.
<variable> can be an environment variable such as:
set( ENV{PATH} /home/martink )
in which case the environment variable will be set.
set_directory_properties
Set a property of the directory.
set_directory_properties(PROPERTIES prop1 value1 prop2 value2)
Set a property for the current directory and subdirectories. If the
property is not found, CMake will report an error. The properties
include: INCLUDE_DIRECTORIES, LINK_DIRECTORIES,
INCLUDE_REGULAR_EXPRESSION, and ADDITIONAL_MAKE_CLEAN_FILES.
ADDITIONAL_MAKE_CLEAN_FILES is a list of files that will be cleaned as
a part of "make clean" stage.
set_property
Set a named property in a given scope.
set_property(<GLOBAL |
DIRECTORY [dir] |
TARGET [target1 [target2 ...]] |
SOURCE [src1 [src2 ...]] |
TEST [test1 [test2 ...]] |
CACHE [entry1 [entry2 ...]]>
[APPEND]
PROPERTY <name> [value1 [value2 ...]])
Set one property on zero or more objects of a scope. The first
argument determines the scope in which the property is set. It must
be one of the following:
GLOBAL scope is unique and does not accept a name.
DIRECTORY scope defaults to the current directory but another
directory (already processed by CMake) may be named by full or
relative path.
TARGET scope may name zero or more existing targets.
SOURCE scope may name zero or more source files.
TEST scope may name zero or more existing tests.
CACHE scope must name zero or more cache existing entries.
The required PROPERTY option is immediately followed by the name of
the property to set. Remaining arguments are used to compose the
property value in the form of a semicolon-separated list. If the
APPEND option is given the list is appended to any existing property
value.
set_source_files_properties
Source files can have properties that affect how they are built.
set_source_files_properties(file1 file2 ...
PROPERTIES prop1 value1
prop2 value2 ...)
Set properties on a file. The syntax for the command is to list all
the files you want to change, and then provide the values you want to
set next. You can make up your own properties as well. The following
are used by CMake. The ABSTRACT flag (boolean) is used by some class
wrapping commands. If WRAP_EXCLUDE (boolean) is true then many
wrapping commands will ignore this file. If GENERATED (boolean) is
true then it is not an error if this source file does not exist when
it is added to a target. Obviously, it must be created (presumably by
a custom command) before the target is built. If the HEADER_FILE_ONLY
(boolean) property is true then the file is not compiled. This is
useful if you want to add extra non build files to an IDE.
OBJECT_DEPENDS (string) adds dependencies to the object file.
COMPILE_FLAGS (string) is passed to the compiler as additional command
line arguments when the source file is compiled. LANGUAGE (string)
CXX|C will change the default compiler used to compile the source
file. The languages used need to be enabled in the PROJECT command.
If SYMBOLIC (boolean) is set to true the build system will be informed
that the source file is not actually created on disk but instead used
as a symbolic name for a build rule.
set_target_properties
Targets can have properties that affect how they are built.
set_target_properties(target1 target2 ...
PROPERTIES prop1 value1
prop2 value2 ...)
Set properties on a target. The syntax for the command is to list all
the files you want to change, and then provide the values you want to
set next. You can use any prop value pair you want and extract it
later with the GET_TARGET_PROPERTY command.
Properties that affect the name of a target's output file are as
follows. The PREFIX and SUFFIX properties override the default target
name prefix (such as "lib") and suffix (such as ".so"). IMPORT_PREFIX
and IMPORT_SUFFIX are the equivalent properties for the import library
corresponding to a DLL (for SHARED library targets). OUTPUT_NAME sets
the real name of a target when it is built and can be used to help
create two targets of the same name even though CMake requires unique
logical target names. There is also a <CONFIG>_OUTPUT_NAME that can
set the output name on a per-configuration basis. <CONFIG>_POSTFIX
sets a postfix for the real name of the target when it is built under
the configuration named by <CONFIG> (in upper-case, such as
"DEBUG_POSTFIX"). The value of this property is initialized when the
target is created to the value of the variable CMAKE_<CONFIG>_POSTFIX
(except for executable targets because earlier CMake versions which
did not use this variable for executables).
The LINK_FLAGS property can be used to add extra flags to the link
step of a target. LINK_FLAGS_<CONFIG> will add to the configuration
<CONFIG>, for example, DEBUG, RELEASE, MINSIZEREL, RELWITHDEBINFO.
DEFINE_SYMBOL sets the name of the preprocessor symbol defined when
compiling sources in a shared library. If not set here then it is set
to target_EXPORTS by default (with some substitutions if the target is
not a valid C identifier). This is useful for headers to know whether
they are being included from inside their library our outside to
properly setup dllexport/dllimport decorations. The COMPILE_FLAGS
property sets additional compiler flags used to build sources within
the target. It may also be used to pass additional preprocessor
definitions.
The LINKER_LANGUAGE property is used to change the tool used to link
an executable or shared library. The default is set the language to
match the files in the library. CXX and C are common values for this
property.
For shared libraries VERSION and SOVERSION can be used to specify the
build version and api version respectively. When building or
installing appropriate symlinks are created if the platform supports
symlinks and the linker supports so-names. If only one of both is
specified the missing is assumed to have the same version number. For
executables VERSION can be used to specify the build version. When
building or installing appropriate symlinks are created if the
platform supports symlinks. For shared libraries and executables on
Windows the VERSION attribute is parsed to extract a "major.minor"
version number. These numbers are used as the image version of the
binary.
There are a few properties used to specify RPATH rules. INSTALL_RPATH
is a semicolon-separated list specifying the rpath to use in installed
targets (for platforms that support it). INSTALL_RPATH_USE_LINK_PATH
is a boolean that if set to true will append directories in the linker
search path and outside the project to the INSTALL_RPATH.
SKIP_BUILD_RPATH is a boolean specifying whether to skip automatic
generation of an rpath allowing the target to run from the build tree.
BUILD_WITH_INSTALL_RPATH is a boolean specifying whether to link the
target in the build tree with the INSTALL_RPATH. This takes
precedence over SKIP_BUILD_RPATH and avoids the need for relinking
before installation. INSTALL_NAME_DIR is a string specifying the
directory portion of the "install_name" field of shared libraries on
Mac OSX to use in the installed targets. When the target is created
the values of the variables CMAKE_INSTALL_RPATH,
CMAKE_INSTALL_RPATH_USE_LINK_PATH, CMAKE_SKIP_BUILD_RPATH,
CMAKE_BUILD_WITH_INSTALL_RPATH, and CMAKE_INSTALL_NAME_DIR are used to
initialize these properties.
PROJECT_LABEL can be used to change the name of the target in an IDE
like visual studio. VS_KEYWORD can be set to change the visual studio
keyword, for example QT integration works better if this is set to
Qt4VSv1.0.
VS_SCC_PROJECTNAME, VS_SCC_LOCALPATH, VS_SCC_PROVIDER can be set to
add support for source control bindings in a Visual Studio project
file.
The PRE_INSTALL_SCRIPT and POST_INSTALL_SCRIPT properties are the old
way to specify CMake scripts to run before and after installing a
target. They are used only when the old INSTALL_TARGETS command is
used to install the target. Use the INSTALL command instead.
The EXCLUDE_FROM_DEFAULT_BUILD property is used by the visual studio
generators. If it is set to 1 the target will not be part of the
default build when you select "Build Solution".
set_tests_properties
Set a property of the tests.
set_tests_properties(test1 [test2...] PROPERTIES prop1 value1 prop2 value2)
Set a property for the tests. If the property is not found, CMake
will report an error. The properties include:
WILL_FAIL: If set to true, this will invert the pass/fail flag of the
test.
PASS_REGULAR_EXPRESSION: If set, the test output will be checked
against the specified regular expressions and at least one of the
regular expressions has to match, otherwise the test will fail.
Example: PASS_REGULAR_EXPRESSION "TestPassed;All ok"
FAIL_REGULAR_EXPRESSION: If set, if the output will match to one of
specified regular expressions, the test will fail.
Example: PASS_REGULAR_EXPRESSION "[^a-z]Error;ERROR;Failed"
Both PASS_REGULAR_EXPRESSION and FAIL_REGULAR_EXPRESSION expect a list
of regular expressions.
PROCESSORS: Denotes the number of processors that this test will
require. This is typically used for MPI tests, and should be used in
conjunction with the ctest_test PARALLEL_LEVEL option.
COST: Set this to a floating point value. Tests in a test set will be
run in descending order of cost.
RUN_SERIAL: If set to true, this test will not run in parallel with
any other tests. This should be used in conjunction with the
ctest_test PARALLEL_LEVEL option.
site_name
Set the given variable to the name of the computer.
site_name(variable)
source_group
Define a grouping for sources in the makefile.
source_group(name [REGULAR_EXPRESSION regex] [FILES src1 src2 ...])
Defines a group into which sources will be placed in project files.
This is mainly used to setup file tabs in Visual Studio. Any file
whose name is listed or matches the regular expression will be placed
in this group. If a file matches multiple groups, the LAST group that
explicitly lists the file will be favored, if any. If no group
explicitly lists the file, the LAST group whose regular expression
matches the file will be favored.
The name of the group may contain backslashes to specify subgroups:
source_group(outer\\inner ...)
For backwards compatibility, this command is also supports the format:
source_group(name regex)
string
String operations.
string(REGEX MATCH <regular_expression>
<output variable> <input> [<input>...])
string(REGEX MATCHALL <regular_expression>
<output variable> <input> [<input>...])
string(REGEX REPLACE <regular_expression>
<replace_expression> <output variable>
<input> [<input>...])
string(REPLACE <match_string>
<replace_string> <output variable>
<input> [<input>...])
string(COMPARE EQUAL <string1> <string2> <output variable>)
string(COMPARE NOTEQUAL <string1> <string2> <output variable>)
string(COMPARE LESS <string1> <string2> <output variable>)
string(COMPARE GREATER <string1> <string2> <output variable>)
string(ASCII <number> [<number> ...] <output variable>)
string(CONFIGURE <string1> <output variable>
[@ONLY] [ESCAPE_QUOTES])
string(TOUPPER <string1> <output variable>)
string(TOLOWER <string1> <output variable>)
string(LENGTH <string> <output variable>)
string(SUBSTRING <string> <begin> <length> <output variable>)
string(STRIP <string> <output variable>)
string(RANDOM [LENGTH <length>] [ALPHABET <alphabet>]
[RANDOM_SEED <seed>] <output variable>)
REGEX MATCH will match the regular expression once and store the match
in the output variable.
REGEX MATCHALL will match the regular expression as many times as
possible and store the matches in the output variable as a list.
REGEX REPLACE will match the regular expression as many times as
possible and substitute the replacement expression for the match in
the output. The replace expression may refer to paren-delimited
subexpressions of the match using \1, \2, ..., \9. Note that two
backslashes (\\1) are required in CMake code to get a backslash
through argument parsing.
REPLACE will replace all occurrences of match_string in the input with
replace_string and store the result in the output.
COMPARE EQUAL/NOTEQUAL/LESS/GREATER will compare the strings and store
true or false in the output variable.
ASCII will convert all numbers into corresponding ASCII characters.
CONFIGURE will transform a string like CONFIGURE_FILE transforms a
file.
TOUPPER/TOLOWER will convert string to upper/lower characters.
LENGTH will return a given string's length.
SUBSTRING will return a substring of a given string.
STRIP will return a substring of a given string with leading and
trailing spaces removed.
RANDOM will return a random string of given length consisting of
characters from the given alphabet. Default length is 5 characters
and default alphabet is all numbers and upper and lower case letters.
If an integer RANDOM_SEED is given, its value will be used to seed the
random number generator.
The following characters have special meaning in regular expressions:
^ Matches at beginning of a line
$ Matches at end of a line
. Matches any single character
[ ] Matches any character(s) inside the brackets
[^ ] Matches any character(s) not inside the brackets
- Matches any character in range on either side of a dash
* Matches preceding pattern zero or more times
+ Matches preceding pattern one or more times
? Matches preceding pattern zero or once only
| Matches a pattern on either side of the |
() Saves a matched subexpression, which can be referenced
in the REGEX REPLACE operation. Additionally it is saved
by all regular expression-related commands, including
e.g. if( MATCHES ), in the variables CMAKE_MATCH_(0..9).
target_link_libraries
Link a target to given libraries.
target_link_libraries(<target> [item1 [item2 [...]]]
[[debug|optimized|general] <item>] ...)
Specify libraries or flags to use when linking a given target. If a
library name matches that of another target in the project a
dependency will automatically be added in the build system to make
sure the library being linked is up-to-date before the target links.
Item names starting with '-', but not '-l' or '-framework', are
treated as linker flags.
A "debug", "optimized", or "general" keyword indicates that the
library immediately following it is to be used only for the
corresponding build configuration. The "debug" keyword corresponds to
the Debug configuration (or to configurations named in the
DEBUG_CONFIGURATIONS global property if it is set). The "optimized"
keyword corresponds to all other configurations. The "general"
keyword corresponds to all configurations, and is purely optional
(assumed if omitted). Higher granularity may be achieved for
per-configuration rules by creating and linking to IMPORTED library
targets. See the IMPORTED mode of the add_library command for more
information.
Library dependencies are transitive by default. When this target is
linked into another target then the libraries linked to this target
will appear on the link line for the other target too. See the
LINK_INTERFACE_LIBRARIES target property to override the set of
transitive link dependencies for a target.
target_link_libraries(<target> LINK_INTERFACE_LIBRARIES
[[debug|optimized|general] <lib>] ...)
The LINK_INTERFACE_LIBRARIES mode appends the libraries to the
LINK_INTERFACE_LIBRARIES and its per-configuration equivalent target
properties instead of using them for linking. Libraries specified as
"debug" are appended to the the LINK_INTERFACE_LIBRARIES_DEBUG
property (or to the properties corresponding to configurations listed
in the DEBUG_CONFIGURATIONS global property if it is set). Libraries
specified as "optimized" are appended to the the
LINK_INTERFACE_LIBRARIES property. Libraries specified as "general"
(or without any keyword) are treated as if specified for both "debug"
and "optimized".
The library dependency graph is normally acyclic (a DAG), but in the
case of mutually-dependent STATIC libraries CMake allows the graph to
contain cycles (strongly connected components). When another target
links to one of the libraries CMake repeats the entire connected
component. For example, the code
add_library(A STATIC a.c)
add_library(B STATIC b.c)
target_link_libraries(A B)
target_link_libraries(B A)
add_executable(main main.c)
target_link_libraries(main A)
links 'main' to 'A B A B'. (While one repetition is usually
sufficient, pathological object file and symbol arrangements can
require more. One may handle such cases by manually repeating the
component in the last target_link_libraries call. However, if two
archives are really so interdependent they should probably be combined
into a single archive.)
try_compile
Try compiling some code.
try_compile(RESULT_VAR bindir srcdir
projectName <targetname> [CMAKE_FLAGS <Flags>]
[OUTPUT_VARIABLE var])
Try compiling a program. In this form, srcdir should contain a
complete CMake project with a CMakeLists.txt file and all sources.
The bindir and srcdir will not be deleted after this command is run.
If <target name> is specified then build just that target otherwise
the all or ALL_BUILD target is built.
try_compile(RESULT_VAR bindir srcfile
[CMAKE_FLAGS <Flags>]
[COMPILE_DEFINITIONS <flags> ...]
[OUTPUT_VARIABLE var]
[COPY_FILE <filename> )
Try compiling a srcfile. In this case, the user need only supply a
source file. CMake will create the appropriate CMakeLists.txt file to
build the source. If COPY_FILE is used, the compiled file will be
copied to the given file.
In this version all files in bindir/CMakeFiles/CMakeTmp, will be
cleaned automatically, for debugging a --debug-trycompile can be
passed to cmake to avoid the clean. Some extra flags that can be
included are, INCLUDE_DIRECTORIES, LINK_DIRECTORIES, and
LINK_LIBRARIES. COMPILE_DEFINITIONS are -Ddefinition that will be
passed to the compile line. try_compile creates a CMakeList.txt file
on the fly that looks like this:
add_definitions( <expanded COMPILE_DEFINITIONS from calling cmake>)
include_directories(${INCLUDE_DIRECTORIES})
link_directories(${LINK_DIRECTORIES})
add_executable(cmTryCompileExec sources)
target_link_libraries(cmTryCompileExec ${LINK_LIBRARIES})
In both versions of the command, if OUTPUT_VARIABLE is specified, then
the output from the build process is stored in the given variable.
Return the success or failure in RESULT_VAR. CMAKE_FLAGS can be used
to pass -DVAR:TYPE=VALUE flags to the cmake that is run during the
build.
try_run
Try compiling and then running some code.
try_run(RUN_RESULT_VAR COMPILE_RESULT_VAR
bindir srcfile [CMAKE_FLAGS <Flags>]
[COMPILE_DEFINITIONS <flags>]
[COMPILE_OUTPUT_VARIABLE comp]
[RUN_OUTPUT_VARIABLE run]
[OUTPUT_VARIABLE var]
[ARGS <arg1> <arg2>...])
Try compiling a srcfile. Return TRUE or FALSE for success or failure
in COMPILE_RESULT_VAR. Then if the compile succeeded, run the
executable and return its exit code in RUN_RESULT_VAR. If the
executable was built, but failed to run, then RUN_RESULT_VAR will be
set to FAILED_TO_RUN. COMPILE_OUTPUT_VARIABLE specifies the variable
where the output from the compile step goes. RUN_OUTPUT_VARIABLE
specifies the variable where the output from the running executable
goes.
For compatibility reasons OUTPUT_VARIABLE is still supported, which
gives you the output from the compile and run step combined.
Cross compiling issues
When cross compiling, the executable compiled in the first step
usually cannot be run on the build host. try_run() checks the
CMAKE_CROSSCOMPILING variable to detect whether CMake is in
crosscompiling mode. If that's the case, it will still try to compile
the executable, but it will not try to run the executable. Instead it
will create cache variables which must be filled by the user or by
presetting them in some CMake script file to the values the executable
would have produced if it would have been run on its actual target
platform. These variables are RUN_RESULT_VAR (explanation see above)
and if RUN_OUTPUT_VARIABLE (or OUTPUT_VARIABLE) was used, an
additional cache variable
RUN_RESULT_VAR__COMPILE_RESULT_VAR__TRYRUN_OUTPUT.This is intended to
hold stdout and stderr from the executable.
In order to make cross compiling your project easier, use try_run only
if really required. If you use try_run, use RUN_OUTPUT_VARIABLE (or
OUTPUT_VARIABLE) only if really required. Using them will require
that when crosscompiling, the cache variables will have to be set
manually to the output of the executable. You can also "guard" the
calls to try_run with if(CMAKE_CROSSCOMPILING) and provide an
easy-to-preset alternative for this case.
unset
Unset a variable, cache variable, or environment variable.
unset(<variable> [CACHE])
Removes the specified variable causing it to become undefined. If
CACHE is present then the variable is removed from the cache instead
of the current scope.
<variable> can be an environment variable such as:
unset(ENV{LD_LIBRARY_PATH})
in which case the variable will be removed from the current
environment.
variable_watch
Watch the CMake variable for change.
variable_watch(<variable name> [<command to execute>])
If the specified variable changes, the message will be printed about
the variable being changed. If the command is specified, the command
will be executed. The command will receive the following arguments:
COMMAND(<variable> <access> <value> <current list file> <stack>)
while
Evaluate a group of commands while a condition is true
while(condition)
COMMAND1(ARGS ...)
COMMAND2(ARGS ...)
...
endwhile(condition)
All commands between while and the matching endwhile are recorded
without being invoked. Once the endwhile is evaluated, the recorded
list of commands is invoked as long as the condition is true. The
condition is evaluated using the same logic as the if command.
------------------------------------------------------------------------------
Properties
CMake Properties - Properties supported by CMake, the Cross-Platform Makefile Generator.
This is the documentation for the properties supported by CMake. Properties
can have different scopes. They can either be assigned to a source file, a
directory, a target or globally to CMake. By modifying the values of
properties the behaviour of the build system can be customized.
------------------------------------------------------------------------------
Properties of Global Scope
ALLOW_DUPLICATE_CUSTOM_TARGETS
Allow duplicate custom targets to be created.
Normally CMake requires that all targets built in a project have
globally unique logical names (see policy CMP0002). This is necessary
to generate meaningful project file names in Xcode and VS IDE
generators. It also allows the target names to be referenced
unambiguously.
Makefile generators are capable of supporting duplicate custom target
names. For projects that care only about Makefile generators and do
not wish to support Xcode or VS IDE generators, one may set this
property to true to allow duplicate custom targets. The property
allows multiple add_custom_target command calls in different
directories to specify the same target name. However, setting this
property will cause non-Makefile generators to produce an error and
refuse to generate the project.
DEBUG_CONFIGURATIONS
Specify which configurations are for debugging.
The value must be a semi-colon separated list of configuration names.
Currently this property is used only by the target_link_libraries
command (see its documentation for details). Additional uses may be
defined in the future.
This property must be set at the top level of the project and before
the first target_link_libraries command invocation. If any entry in
the list does not match a valid configuration for the project the
behavior is undefined.
DISABLED_FEATURES
List of features which are disabled during the CMake run.
List of features which are disabled during the CMake run. Be default
it contains the names of all packages which were not found. This is
determined using the <NAME>_FOUND variables. Packages which are
searched QUIET are not listed. A project can add its own features to
this list.This property is used by the macros in FeatureSummary.cmake.
ENABLED_FEATURES
List of features which are enabled during the CMake run.
List of features which are enabled during the CMake run. Be default
it contains the names of all packages which were found. This is
determined using the <NAME>_FOUND variables. Packages which are
searched QUIET are not listed. A project can add its own features to
this list.This property is used by the macros in FeatureSummary.cmake.
ENABLED_LANGUAGES
Read-only property that contains the list of currently enabled
languages
Set to list of currently enabled languages.
FIND_LIBRARY_USE_LIB64_PATHS
Whether FIND_LIBRARY should automatically search lib64 directories.
FIND_LIBRARY_USE_LIB64_PATHS is a boolean specifying whether the
FIND_LIBRARY command should automatically search the lib64 variant of
directories called lib in the search path when building 64-bit
binaries.
FIND_LIBRARY_USE_OPENBSD_VERSIONING
Whether FIND_LIBRARY should find OpenBSD-style shared libraries.
This property is a boolean specifying whether the FIND_LIBRARY command
should find shared libraries with OpenBSD-style versioned extension:
".so.<major>.<minor>". The property is set to true on OpenBSD and
false on other platforms.
GLOBAL_DEPENDS_DEBUG_MODE
Enable global target dependency graph debug mode.
CMake automatically analyzes the global inter-target dependency graph
at the beginning of native build system generation. This property
causes it to display details of its analysis to stderr.
GLOBAL_DEPENDS_NO_CYCLES
Disallow global target dependency graph cycles.
CMake automatically analyzes the global inter-target dependency graph
at the beginning of native build system generation. It reports an
error if the dependency graph contains a cycle that does not consist
of all STATIC library targets. This property tells CMake to disallow
all cycles completely, even among static libraries.
IN_TRY_COMPILE
Read-only property that is true during a try-compile configuration.
True when building a project inside a TRY_COMPILE or TRY_RUN command.
PACKAGES_FOUND
List of packages which were found during the CMake run.
List of packages which were found during the CMake run. Whether a
package has been found is determined using the <NAME>_FOUND variables.
PACKAGES_NOT_FOUND
List of packages which were not found during the CMake run.
List of packages which were not found during the CMake run. Whether a
package has been found is determined using the <NAME>_FOUND variables.
REPORT_UNDEFINED_PROPERTIES
If set, report any undefined properties to this file.
If this property is set to a filename then when CMake runs it will
report any properties or variables that were accessed but not defined
into the filename specified in this property.
RULE_LAUNCH_COMPILE
Specify a launcher for compile rules.
Makefile generators prefix compiler commands with the given launcher
command line. This is intended to allow launchers to intercept build
problems with high granularity. Non-Makefile generators currently
ignore this property.
RULE_LAUNCH_CUSTOM
Specify a launcher for custom rules.
Makefile generators prefix custom commands with the given launcher
command line. This is intended to allow launchers to intercept build
problems with high granularity. Non-Makefile generators currently
ignore this property.
RULE_LAUNCH_LINK
Specify a launcher for link rules.
Makefile generators prefix link and archive commands with the given
launcher command line. This is intended to allow launchers to
intercept build problems with high granularity. Non-Makefile
generators currently ignore this property.
RULE_MESSAGES
Specify whether to report a message for each make rule.
This property specifies whether Makefile generators should add a
progress message describing what each build rule does. If the
property is not set the default is ON. Set the property to OFF to
disable granular messages and report only as each target completes.
This is intended to allow scripted builds to avoid the build time cost
of detailed reports. If a CMAKE_RULE_MESSAGES cache entry exists its
value initializes the value of this property. Non-Makefile generators
currently ignore this property.
TARGET_ARCHIVES_MAY_BE_SHARED_LIBS
Set if shared libraries may be named like archives.
On AIX shared libraries may be named "lib<name>.a". This property is
set to true on such platforms.
TARGET_SUPPORTS_SHARED_LIBS
Does the target platform support shared libraries.
TARGET_SUPPORTS_SHARED_LIBS is a boolean specifying whether the target
platform supports shared libraries. Basically all current general
general purpose OS do so, the exception are usually embedded systems
with no or special OSs.
__CMAKE_DELETE_CACHE_CHANGE_VARS_
Internal property
Used to detect compiler changes, Do not set.
------------------------------------------------------------------------------
Properties on Directories
ADDITIONAL_MAKE_CLEAN_FILES
Additional files to clean during the make clean stage.
A list of files that will be cleaned as a part of the "make clean"
stage.
CACHE_VARIABLES
List of cache variables available in the current directory.
This read-only property specifies the list of CMake cache variables
currently defined. It is intended for debugging purposes.
CLEAN_NO_CUSTOM
Should the output of custom commands be left.
If this is true then the outputs of custom commands for this directory
will not be removed during the "make clean" stage.
COMPILE_DEFINITIONS
Preprocessor definitions for compiling a directory's sources.
The COMPILE_DEFINITIONS property may be set to a semicolon-separated
list of preprocessor definitions using the syntax VAR or VAR=value.
Function-style definitions are not supported. CMake will
automatically escape the value correctly for the native build system
(note that CMake language syntax may require escapes to specify some
values). This property may be set on a per-configuration basis using
the name COMPILE_DEFINITIONS_<CONFIG> where <CONFIG> is an upper-case
name (ex. "COMPILE_DEFINITIONS_DEBUG"). This property will be
initialized in each directory by its value in the directory's parent.
CMake will automatically drop some definitions that are not supported
by the native build tool. The VS6 IDE does not support definition
values with spaces (but NMake does).
Dislaimer: Most native build tools have poor support for escaping
certain values. CMake has work-arounds for many cases but some values
may just not be possible to pass correctly. If a value does not seem
to be escaped correctly, do not attempt to work-around the problem by
adding escape sequences to the value. Your work-around may break in a
future version of CMake that has improved escape support. Instead
consider defining the macro in a (configured) header file. Then
report the limitation.
COMPILE_DEFINITIONS_<CONFIG>
Per-configuration preprocessor definitions in a directory.
This is the configuration-specific version of COMPILE_DEFINITIONS.
This property will be initialized in each directory by its value in
the directory's parent.
DEFINITIONS
For CMake 2.4 compatibility only. Use COMPILE_DEFINITIONS instead.
This read-only property specifies the list of flags given so far to
the add_definitions command. It is intended for debugging purposes.
Use the COMPILE_DEFINITIONS instead.
EXCLUDE_FROM_ALL
Exclude the directory from the all target of its parent.
A property on a directory that indicates if its targets are excluded
from the default build target. If it is not, then with a Makefile for
example typing make will cause the targets to be built. The same
concept applies to the default build of other generators.
IMPLICIT_DEPENDS_INCLUDE_TRANSFORM
Specify #include line transforms for dependencies in a directory.
This property specifies rules to transform macro-like #include lines
during implicit dependency scanning of C and C++ source files. The
list of rules must be semicolon-separated with each entry of the form
"A_MACRO(%)=value-with-%" (the % must be literal). During dependency
scanning occurrences of A_MACRO(...) on #include lines will be
replaced by the value given with the macro argument substituted for
'%'. For example, the entry
MYDIR(%)=<mydir/%>
will convert lines of the form
#include MYDIR(myheader.h)
to
#include <mydir/myheader.h>
allowing the dependency to be followed.
This property applies to sources in all targets within a directory.
The property value is initialized in each directory by its value in
the directory's parent.
INCLUDE_DIRECTORIES
List of preprocessor include file search directories.
This read-only property specifies the list of directories given so far
to the include_directories command. It is intended for debugging
purposes.
INCLUDE_REGULAR_EXPRESSION
Include file scanning regular expression.
This read-only property specifies the regular expression used during
dependency scanning to match include files that should be followed.
See the include_regular_expression command.
INTERPROCEDURAL_OPTIMIZATION
Enable interprocedural optimization for targets in a directory.
If set to true, enables interprocedural optimizations if they are
known to be supported by the compiler.
INTERPROCEDURAL_OPTIMIZATION_<CONFIG>
Per-configuration interprocedural optimization for a directory.
This is a per-configuration version of INTERPROCEDURAL_OPTIMIZATION.
If set, this property overrides the generic property for the named
configuration.
LINK_DIRECTORIES
List of linker search directories.
This read-only property specifies the list of directories given so far
to the link_directories command. It is intended for debugging
purposes.
LISTFILE_STACK
The current stack of listfiles being processed.
This property is mainly useful when trying to debug errors in your
CMake scripts. It returns a list of what list files are currently
being processed, in order. So if one listfile does an INCLUDE command
then that is effectively pushing the included listfile onto the stack.
MACROS
List of macro commands available in the current directory.
This read-only property specifies the list of CMake macros currently
defined. It is intended for debugging purposes. See the macro
command.
PARENT_DIRECTORY
Source directory that added current subdirectory.
This read-only property specifies the source directory that added the
current source directory as a subdirectory of the build. In the
top-level directory the value is the empty-string.
RULE_LAUNCH_COMPILE
Specify a launcher for compile rules.
See the global property of the same name for details. This overrides
the global property for a directory.
RULE_LAUNCH_CUSTOM
Specify a launcher for custom rules.
See the global property of the same name for details. This overrides
the global property for a directory.
RULE_LAUNCH_LINK
Specify a launcher for link rules.
See the global property of the same name for details. This overrides
the global property for a directory.
TEST_INCLUDE_FILE
A cmake file that will be included when ctest is run.
If you specify TEST_INCLUDE_FILE, that file will be included and
processed when ctest is run on the directory.
VARIABLES
List of variables defined in the current directory.
This read-only property specifies the list of CMake variables
currently defined. It is intended for debugging purposes.
------------------------------------------------------------------------------
Properties on Targets
<CONFIG>_OUTPUT_NAME
Old per-configuration target file base name.
This is a configuration-specific version of OUTPUT_NAME. Use
OUTPUT_NAME_<CONFIG> instead.
<CONFIG>_POSTFIX
Postfix to append to the target file name for configuration <CONFIG>.
When building with configuration <CONFIG> the value of this property
is appended to the target file name built on disk. For non-executable
targets, this property is initialized by the value of the variable
CMAKE_<CONFIG>_POSTFIX if it is set when a target is created. This
property is ignored on the Mac for Frameworks and App Bundles.
ARCHIVE_OUTPUT_DIRECTORY
Output directory in which to build ARCHIVE target files.
This property specifies the directory into which archive target files
should be built. There are three kinds of target files that may be
built: archive, library, and runtime. Executables are always treated
as runtime targets. Static libraries are always treated as archive
targets. Module libraries are always treated as library targets. For
non-DLL platforms shared libraries are treated as library targets.
For DLL platforms the DLL part of a shared library is treated as a
runtime target and the corresponding import library is treated as an
archive target. All Windows-based systems including Cygwin are DLL
platforms. This property is initialized by the value of the variable
CMAKE_ARCHIVE_OUTPUT_DIRECTORY if it is set when a target is created.
ARCHIVE_OUTPUT_NAME
Output name for ARCHIVE target files.
This property specifies the base name for archive target files. It
overrides OUTPUT_NAME and OUTPUT_NAME_<CONFIG> properties. There are
three kinds of target files that may be built: archive, library, and
runtime. Executables are always treated as runtime targets. Static
libraries are always treated as archive targets. Module libraries are
always treated as library targets. For non-DLL platforms shared
libraries are treated as library targets. For DLL platforms the DLL
part of a shared library is treated as a runtime target and the
corresponding import library is treated as an archive target. All
Windows-based systems including Cygwin are DLL platforms.
ARCHIVE_OUTPUT_NAME_<CONFIG>
Per-configuration output name for ARCHIVE target files.
This is the configuration-specific version of ARCHIVE_OUTPUT_NAME.
BUILD_WITH_INSTALL_RPATH
Should build tree targets have install tree rpaths.
BUILD_WITH_INSTALL_RPATH is a boolean specifying whether to link the
target in the build tree with the INSTALL_RPATH. This takes
precedence over SKIP_BUILD_RPATH and avoids the need for relinking
before installation. This property is initialized by the value of the
variable CMAKE_BUILD_WITH_INSTALL_RPATH if it is set when a target is
created.
COMPILE_DEFINITIONS
Preprocessor definitions for compiling a target's sources.
The COMPILE_DEFINITIONS property may be set to a semicolon-separated
list of preprocessor definitions using the syntax VAR or VAR=value.
Function-style definitions are not supported. CMake will
automatically escape the value correctly for the native build system
(note that CMake language syntax may require escapes to specify some
values). This property may be set on a per-configuration basis using
the name COMPILE_DEFINITIONS_<CONFIG> where <CONFIG> is an upper-case
name (ex. "COMPILE_DEFINITIONS_DEBUG").
CMake will automatically drop some definitions that are not supported
by the native build tool. The VS6 IDE does not support definition
values with spaces (but NMake does).
Dislaimer: Most native build tools have poor support for escaping
certain values. CMake has work-arounds for many cases but some values
may just not be possible to pass correctly. If a value does not seem
to be escaped correctly, do not attempt to work-around the problem by
adding escape sequences to the value. Your work-around may break in a
future version of CMake that has improved escape support. Instead
consider defining the macro in a (configured) header file. Then
report the limitation.
COMPILE_DEFINITIONS_<CONFIG>
Per-configuration preprocessor definitions on a target.
This is the configuration-specific version of COMPILE_DEFINITIONS.
COMPILE_FLAGS
Additional flags to use when compiling this target's sources.
The COMPILE_FLAGS property sets additional compiler flags used to
build sources within the target. Use COMPILE_DEFINITIONS to pass
additional preprocessor definitions.
DEBUG_POSTFIX
See target property <CONFIG>_POSTFIX.
This property is a special case of the more-general <CONFIG>_POSTFIX
property for the DEBUG configuration.
DEFINE_SYMBOL
Define a symbol when compiling this target's sources.
DEFINE_SYMBOL sets the name of the preprocessor symbol defined when
compiling sources in a shared library. If not set here then it is set
to target_EXPORTS by default (with some substitutions if the target is
not a valid C identifier). This is useful for headers to know whether
they are being included from inside their library our outside to
properly setup dllexport/dllimport decorations.
ENABLE_EXPORTS
Specify whether an executable exports symbols for loadable modules.
Normally an executable does not export any symbols because it is the
final program. It is possible for an executable to export symbols to
be used by loadable modules. When this property is set to true CMake
will allow other targets to "link" to the executable with the
TARGET_LINK_LIBRARIES command. On all platforms a target-level
dependency on the executable is created for targets that link to it.
For non-DLL platforms the link rule is simply ignored since the
dynamic loader will automatically bind symbols when the module is
loaded. For DLL platforms an import library will be created for the
exported symbols and then used for linking. All Windows-based systems
including Cygwin are DLL platforms.
EXCLUDE_FROM_ALL
Exclude the target from the all target.
A property on a target that indicates if the target is excluded from
the default build target. If it is not, then with a Makefile for
example typing make will cause this target to be built. The same
concept applies to the default build of other generators. Installing
a target with EXCLUDE_FROM_ALL set to true has undefined behavior.
EchoString
A message to be displayed when the target is built.
A message to display on some generators (such as makefiles) when the
target is built.
FRAMEWORK
This target is a framework on the Mac.
If a shared library target has this property set to true it will be
built as a framework when built on the mac. It will have the
directory structure required for a framework and will be suitable to
be used with the -framework option
Fortran_MODULE_DIRECTORY
Specify output directory for Fortran modules provided by the target.
If the target contains Fortran source files that provide modules and
the compiler supports a module output directory this specifies the
directory in which the modules will be placed. When this property is
not set the modules will be placed in the build directory
corresponding to the target's source directory. If the variable
CMAKE_Fortran_MODULE_DIRECTORY is set when a target is created its
value is used to initialize this property.
GENERATOR_FILE_NAME
Generator's file for this target.
An internal property used by some generators to record the name of
project or dsp file associated with this target.
HAS_CXX
Link the target using the C++ linker tool (obselete).
This is equivalent to setting the LINKER_LANGUAGE property to CXX.
See that property's documentation for details.
IMPLICIT_DEPENDS_INCLUDE_TRANSFORM
Specify #include line transforms for dependencies in a target.
This property specifies rules to transform macro-like #include lines
during implicit dependency scanning of C and C++ source files. The
list of rules must be semicolon-separated with each entry of the form
"A_MACRO(%)=value-with-%" (the % must be literal). During dependency
scanning occurrences of A_MACRO(...) on #include lines will be
replaced by the value given with the macro argument substituted for
'%'. For example, the entry
MYDIR(%)=<mydir/%>
will convert lines of the form
#include MYDIR(myheader.h)
to
#include <mydir/myheader.h>
allowing the dependency to be followed.
This property applies to sources in the target on which it is set.
IMPORTED
Read-only indication of whether a target is IMPORTED.
The boolean value of this property is true for targets created with
the IMPORTED option to add_executable or add_library. It is false for
targets built within the project.
IMPORTED_CONFIGURATIONS
Configurations provided for an IMPORTED target.
Lists configuration names available for an IMPORTED target. The names
correspond to configurations defined in the project from which the
target is imported. If the importing project uses a different set of
configurations the names may be mapped using the
MAP_IMPORTED_CONFIG_<CONFIG> property. Ignored for non-imported
targets.
IMPORTED_IMPLIB
Full path to the import library for an IMPORTED target.
Specifies the location of the ".lib" part of a windows DLL. Ignored
for non-imported targets.
IMPORTED_IMPLIB_<CONFIG>
Per-configuration version of IMPORTED_IMPLIB property.
This property is used when loading settings for the <CONFIG>
configuration of an imported target. Configuration names correspond
to those provided by the project from which the target is imported.
IMPORTED_LINK_DEPENDENT_LIBRARIES
Dependent shared libraries of an imported shared library.
Shared libraries may be linked to other shared libraries as part of
their implementation. On some platforms the linker searches for the
dependent libraries of shared libraries they are including in the
link. This property lists the dependent shared libraries of an
imported library. The list should be disjoint from the list of
interface libraries in the IMPORTED_LINK_INTERFACE_LIBRARIES property.
On platforms requiring dependent shared libraries to be found at link
time CMake uses this list to add appropriate files or paths to the
link command line. Ignored for non-imported targets.
IMPORTED_LINK_DEPENDENT_LIBRARIES_<CONFIG>
Per-configuration version of IMPORTED_LINK_DEPENDENT_LIBRARIES.
This property is used when loading settings for the <CONFIG>
configuration of an imported target. Configuration names correspond
to those provided by the project from which the target is imported.
If set, this property completely overrides the generic property for
the named configuration.
IMPORTED_LINK_INTERFACE_LANGUAGES
Languages compiled into an IMPORTED static library.
Lists languages of soure files compiled to produce a STATIC IMPORTED
library (such as "C" or "CXX"). CMake accounts for these languages
when computing how to link a target to the imported library. For
example, when a C executable links to an imported C++ static library
CMake chooses the C++ linker to satisfy language runtime dependencies
of the static library.
This property is ignored for targets that are not STATIC libraries.
This property is ignored for non-imported targets.
IMPORTED_LINK_INTERFACE_LANGUAGES_<CONFIG>
Per-configuration version of IMPORTED_LINK_INTERFACE_LANGUAGES.
This property is used when loading settings for the <CONFIG>
configuration of an imported target. Configuration names correspond
to those provided by the project from which the target is imported.
If set, this property completely overrides the generic property for
the named configuration.
IMPORTED_LINK_INTERFACE_LIBRARIES
Transitive link interface of an IMPORTED target.
Lists libraries whose interface is included when an IMPORTED library
target is linked to another target. The libraries will be included on
the link line for the target. Unlike the LINK_INTERFACE_LIBRARIES
property, this property applies to all imported target types,
including STATIC libraries. This property is ignored for non-imported
targets.
IMPORTED_LINK_INTERFACE_LIBRARIES_<CONFIG>
Per-configuration version of IMPORTED_LINK_INTERFACE_LIBRARIES.
This property is used when loading settings for the <CONFIG>
configuration of an imported target. Configuration names correspond
to those provided by the project from which the target is imported.
If set, this property completely overrides the generic property for
the named configuration.
IMPORTED_LINK_INTERFACE_MULTIPLICITY
Repetition count for cycles of IMPORTED static libraries.
This is LINK_INTERFACE_MULTIPLICITY for IMPORTED targets.
IMPORTED_LINK_INTERFACE_MULTIPLICITY_<CONFIG>
Per-configuration repetition count for cycles of IMPORTED archives.
This is the configuration-specific version of
IMPORTED_LINK_INTERFACE_MULTIPLICITY. If set, this property
completely overrides the generic property for the named configuration.
IMPORTED_LOCATION
Full path to the main file on disk for an IMPORTED target.
Specifies the location of an IMPORTED target file on disk. For
executables this is the location of the executable file. For bundles
on OS X this is the location of the executable file inside
Contents/MacOS under the application bundle folder. For static
libraries and modules this is the location of the library or module.
For shared libraries on non-DLL platforms this is the location of the
shared library. For frameworks on OS X this is the location of the
library file symlink just inside the framework folder. For DLLs this
is the location of the ".dll" part of the library. For UNKNOWN
libraries this is the location of the file to be linked. Ignored for
non-imported targets.
IMPORTED_LOCATION_<CONFIG>
Per-configuration version of IMPORTED_LOCATION property.
This property is used when loading settings for the <CONFIG>
configuration of an imported target. Configuration names correspond
to those provided by the project from which the target is imported.
IMPORTED_SONAME
The "soname" of an IMPORTED target of shared library type.
Specifies the "soname" embedded in an imported shared library. This
is meaningful only on platforms supporting the feature. Ignored for
non-imported targets.
IMPORTED_SONAME_<CONFIG>
Per-configuration version of IMPORTED_SONAME property.
This property is used when loading settings for the <CONFIG>
configuration of an imported target. Configuration names correspond
to those provided by the project from which the target is imported.
IMPORT_PREFIX
What comes before the import library name.
Similar to the target property PREFIX, but used for import libraries
(typically corresponding to a DLL) instead of regular libraries. A
target property that can be set to override the prefix (such as "lib")
on an import library name.
IMPORT_SUFFIX
What comes after the import library name.
Similar to the target property SUFFIX, but used for import libraries
(typically corresponding to a DLL) instead of regular libraries. A
target property that can be set to override the suffix (such as
".lib") on an import library name.
INSTALL_NAME_DIR
Mac OSX directory name for installed targets.
INSTALL_NAME_DIR is a string specifying the directory portion of the
"install_name" field of shared libraries on Mac OSX to use in the
installed targets.
INSTALL_RPATH
The rpath to use for installed targets.
A semicolon-separated list specifying the rpath to use in installed
targets (for platforms that support it). This property is initialized
by the value of the variable CMAKE_INSTALL_RPATH if it is set when a
target is created.
INSTALL_RPATH_USE_LINK_PATH
Add paths to linker search and installed rpath.
INSTALL_RPATH_USE_LINK_PATH is a boolean that if set to true will
append directories in the linker search path and outside the project
to the INSTALL_RPATH. This property is initialized by the value of
the variable CMAKE_INSTALL_RPATH_USE_LINK_PATH if it is set when a
target is created.
INTERPROCEDURAL_OPTIMIZATION
Enable interprocedural optimization for a target.
If set to true, enables interprocedural optimizations if they are
known to be supported by the compiler.
INTERPROCEDURAL_OPTIMIZATION_<CONFIG>
Per-configuration interprocedural optimization for a target.
This is a per-configuration version of INTERPROCEDURAL_OPTIMIZATION.
If set, this property overrides the generic property for the named
configuration.
LABELS
Specify a list of text labels associated with a target.
Target label semantics are currently unspecified.
LIBRARY_OUTPUT_DIRECTORY
Output directory in which to build LIBRARY target files.
This property specifies the directory into which library target files
should be built. There are three kinds of target files that may be
built: archive, library, and runtime. Executables are always treated
as runtime targets. Static libraries are always treated as archive
targets. Module libraries are always treated as library targets. For
non-DLL platforms shared libraries are treated as library targets.
For DLL platforms the DLL part of a shared library is treated as a
runtime target and the corresponding import library is treated as an
archive target. All Windows-based systems including Cygwin are DLL
platforms. This property is initialized by the value of the variable
CMAKE_LIBRARY_OUTPUT_DIRECTORY if it is set when a target is created.
LIBRARY_OUTPUT_NAME
Output name for LIBRARY target files.
This property specifies the base name for library target files. It
overrides OUTPUT_NAME and OUTPUT_NAME_<CONFIG> properties. There are
three kinds of target files that may be built: archive, library, and
runtime. Executables are always treated as runtime targets. Static
libraries are always treated as archive targets. Module libraries are
always treated as library targets. For non-DLL platforms shared
libraries are treated as library targets. For DLL platforms the DLL
part of a shared library is treated as a runtime target and the
corresponding import library is treated as an archive target. All
Windows-based systems including Cygwin are DLL platforms.
LIBRARY_OUTPUT_NAME_<CONFIG>
Per-configuration output name for LIBRARY target files.
This is the configuration-specific version of LIBRARY_OUTPUT_NAME.
LINKER_LANGUAGE
Specifies language whose compiler will invoke the linker.
For executables, shared libraries, and modules, this sets the language
whose compiler is used to link the target (such as "C" or "CXX"). A
typical value for an executable is the language of the source file
providing the program entry point (main). If not set, the language
with the highest linker preference value is the default. See
documentation of CMAKE_<LANG>_LINKER_PREFERENCE variables.
LINK_FLAGS
Additional flags to use when linking this target.
The LINK_FLAGS property can be used to add extra flags to the link
step of a target. LINK_FLAGS_<CONFIG> will add to the configuration
<CONFIG>, for example, DEBUG, RELEASE, MINSIZEREL, RELWITHDEBINFO.
LINK_FLAGS_<CONFIG>
Per-configuration linker flags for a target.
This is the configuration-specific version of LINK_FLAGS.
LINK_INTERFACE_LIBRARIES
List public interface libraries for a shared library or executable.
By default linking to a shared library target transitively links to
targets with which the library itself was linked. For an executable
with exports (see the ENABLE_EXPORTS property) no default transitive
link dependencies are used. This property replaces the default
transitive link dependencies with an explict list. When the target is
linked into another target the libraries listed (and recursively their
link interface libraries) will be provided to the other target also.
If the list is empty then no transitive link dependencies will be
incorporated when this target is linked into another target even if
the default set is non-empty. This property is ignored for STATIC
libraries.
LINK_INTERFACE_LIBRARIES_<CONFIG>
Per-configuration list of public interface libraries for a target.
This is the configuration-specific version of
LINK_INTERFACE_LIBRARIES. If set, this property completely overrides
the generic property for the named configuration.
LINK_INTERFACE_MULTIPLICITY
Repetition count for STATIC libraries with cyclic dependencies.
When linking to a STATIC library target with cyclic dependencies the
linker may need to scan more than once through the archives in the
strongly connected component of the dependency graph. CMake by
default constructs the link line so that the linker will scan through
the component at least twice. This property specifies the minimum
number of scans if it is larger than the default. CMake uses the
largest value specified by any target in a component.
LINK_INTERFACE_MULTIPLICITY_<CONFIG>
Per-configuration repetition count for cycles of STATIC libraries.
This is the configuration-specific version of
LINK_INTERFACE_MULTIPLICITY. If set, this property completely
overrides the generic property for the named configuration.
LINK_SEARCH_END_STATIC
End a link line such that static system libraries are used.
Some linkers support switches such as -Bstatic and -Bdynamic to
determine whether to use static or shared libraries for -lXXX options.
CMake uses these options to set the link type for libraries whose full
paths are not known or (in some cases) are in implicit link
directories for the platform. By default the linker search type is
left at -Bdynamic by the end of the library list. This property
switches the final linker search type to -Bstatic.
LOCATION
Read-only location of a target on disk.
For an imported target, this read-only property returns the value of
the LOCATION_<CONFIG> property for an unspecified configuration
<CONFIG> provided by the target.
For a non-imported target, this property is provided for compatibility
with CMake 2.4 and below. It was meant to get the location of an
executable target's output file for use in add_custom_command. The
path may contain a build-system-specific portion that is replaced at
build time with the configuration getting built (such as
"$(ConfigurationName)" in VS). In CMake 2.6 and above
add_custom_command automatically recognizes a target name in its
COMMAND and DEPENDS options and computes the target location.
Therefore this property is not needed for creating custom commands.
LOCATION_<CONFIG>
Read-only property providing a target location on disk.
A read-only property that indicates where a target's main file is
located on disk for the configuration <CONFIG>. The property is
defined only for library and executable targets. An imported target
may provide a set of configurations different from that of the
importing project. By default CMake looks for an exact-match but
otherwise uses an arbitrary available configuration. Use the
MAP_IMPORTED_CONFIG_<CONFIG> property to map imported configurations
explicitly.
MACOSX_BUNDLE
Build an executable as an application bundle on Mac OS X.
When this property is set to true the executable when built on Mac OS
X will be created as an application bundle. This makes it a GUI
executable that can be launched from the Finder. See the
MACOSX_BUNDLE_INFO_PLIST target property for information about
creation of the Info.plist file for the application bundle.
MACOSX_BUNDLE_INFO_PLIST
Specify a custom Info.plist template for a Mac OS X App Bundle.
An executable target with MACOSX_BUNDLE enabled will be built as an
application bundle on Mac OS X. By default its Info.plist file is
created by configuring a template called MacOSXBundleInfo.plist.in
located in the CMAKE_MODULE_PATH. This property specifies an
alternative template file name which may be a full path.
The following target properties may be set to specify content to be
configured into the file:
MACOSX_BUNDLE_INFO_STRING
MACOSX_BUNDLE_ICON_FILE
MACOSX_BUNDLE_GUI_IDENTIFIER
MACOSX_BUNDLE_LONG_VERSION_STRING
MACOSX_BUNDLE_BUNDLE_NAME
MACOSX_BUNDLE_SHORT_VERSION_STRING
MACOSX_BUNDLE_BUNDLE_VERSION
MACOSX_BUNDLE_COPYRIGHT
CMake variables of the same name may be set to affect all targets in a
directory that do not have each specific property set. If a custom
Info.plist is specified by this property it may of course hard-code
all the settings instead of using the target properties.
MACOSX_FRAMEWORK_INFO_PLIST
Specify a custom Info.plist template for a Mac OS X Framework.
An library target with FRAMEWORK enabled will be built as a framework
on Mac OS X. By default its Info.plist file is created by configuring
a template called MacOSXFrameworkInfo.plist.in located in the
CMAKE_MODULE_PATH. This property specifies an alternative template
file name which may be a full path.
The following target properties may be set to specify content to be
configured into the file:
MACOSX_FRAMEWORK_ICON_FILE
MACOSX_FRAMEWORK_IDENTIFIER
MACOSX_FRAMEWORK_SHORT_VERSION_STRING
MACOSX_FRAMEWORK_BUNDLE_VERSION
CMake variables of the same name may be set to affect all targets in a
directory that do not have each specific property set. If a custom
Info.plist is specified by this property it may of course hard-code
all the settings instead of using the target properties.
MAP_IMPORTED_CONFIG_<CONFIG>
Map from project configuration to IMPORTED target's configuration.
List configurations of an imported target that may be used for the
current project's <CONFIG> configuration. Targets imported from
another project may not provide the same set of configuration names
available in the current project. Setting this property tells CMake
what imported configurations are suitable for use when building the
<CONFIG> configuration. The first configuration in the list found to
be provided by the imported target is selected. If no matching
configurations are available the imported target is considered to be
not found. This property is ignored for non-imported targets.
OUTPUT_NAME
Output name for target files.
This sets the base name for output files created for an executable or
library target. If not set, the logical target name is used by
default.
OUTPUT_NAME_<CONFIG>
Per-configuration target file base name.
This is the configuration-specific version of OUTPUT_NAME.
POST_INSTALL_SCRIPT
Deprecated install support.
The PRE_INSTALL_SCRIPT and POST_INSTALL_SCRIPT properties are the old
way to specify CMake scripts to run before and after installing a
target. They are used only when the old INSTALL_TARGETS command is
used to install the target. Use the INSTALL command instead.
PREFIX
What comes before the library name.
A target property that can be set to override the prefix (such as
"lib") on a library name.
PRE_INSTALL_SCRIPT
Deprecated install support.
The PRE_INSTALL_SCRIPT and POST_INSTALL_SCRIPT properties are the old
way to specify CMake scripts to run before and after installing a
target. They are used only when the old INSTALL_TARGETS command is
used to install the target. Use the INSTALL command instead.
PRIVATE_HEADER
Specify private header files in a FRAMEWORK shared library target.
Shared library targets marked with the FRAMEWORK property generate
frameworks on OS X and normal shared libraries on other platforms.
This property may be set to a list of header files to be placed in the
PrivateHeaders directory inside the framework folder. On non-Apple
platforms these headers may be installed using the PRIVATE_HEADER
option to the install(TARGETS) command.
PROJECT_LABEL
Change the name of a target in an IDE.
Can be used to change the name of the target in an IDE like visual
stuido.
PUBLIC_HEADER
Specify public header files in a FRAMEWORK shared library target.
Shared library targets marked with the FRAMEWORK property generate
frameworks on OS X and normal shared libraries on other platforms.
This property may be set to a list of header files to be placed in the
Headers directory inside the framework folder. On non-Apple platforms
these headers may be installed using the PUBLIC_HEADER option to the
install(TARGETS) command.
RESOURCE
Specify resource files in a FRAMEWORK shared library target.
Shared library targets marked with the FRAMEWORK property generate
frameworks on OS X and normal shared libraries on other platforms.
This property may be set to a list of files to be placed in the
Resources directory inside the framework folder. On non-Apple
platforms these files may be installed using the RESOURCE option to
the install(TARGETS) command.
RULE_LAUNCH_COMPILE
Specify a launcher for compile rules.
See the global property of the same name for details. This overrides
the global and directory property for a target.
RULE_LAUNCH_CUSTOM
Specify a launcher for custom rules.
See the global property of the same name for details. This overrides
the global and directory property for a target.
RULE_LAUNCH_LINK
Specify a launcher for link rules.
See the global property of the same name for details. This overrides
the global and directory property for a target.
RUNTIME_OUTPUT_DIRECTORY
Output directory in which to build RUNTIME target files.
This property specifies the directory into which runtime target files
should be built. There are three kinds of target files that may be
built: archive, library, and runtime. Executables are always treated
as runtime targets. Static libraries are always treated as archive
targets. Module libraries are always treated as library targets. For
non-DLL platforms shared libraries are treated as library targets.
For DLL platforms the DLL part of a shared library is treated as a
runtime target and the corresponding import library is treated as an
archive target. All Windows-based systems including Cygwin are DLL
platforms. This property is initialized by the value of the variable
CMAKE_RUNTIME_OUTPUT_DIRECTORY if it is set when a target is created.
RUNTIME_OUTPUT_NAME
Output name for RUNTIME target files.
This property specifies the base name for runtime target files. It
overrides OUTPUT_NAME and OUTPUT_NAME_<CONFIG> properties. There are
three kinds of target files that may be built: archive, library, and
runtime. Executables are always treated as runtime targets. Static
libraries are always treated as archive targets. Module libraries are
always treated as library targets. For non-DLL platforms shared
libraries are treated as library targets. For DLL platforms the DLL
part of a shared library is treated as a runtime target and the
corresponding import library is treated as an archive target. All
Windows-based systems including Cygwin are DLL platforms.
RUNTIME_OUTPUT_NAME_<CONFIG>
Per-configuration output name for RUNTIME target files.
This is the configuration-specific version of RUNTIME_OUTPUT_NAME.
SKIP_BUILD_RPATH
Should rpaths be used for the build tree.
SKIP_BUILD_RPATH is a boolean specifying whether to skip automatic
generation of an rpath allowing the target to run from the build tree.
This property is initialized by the value of the variable
CMAKE_SKIP_BUILD_RPATH if it is set when a target is created.
SOURCES
Source names specified for a target.
Read-only list of sources specified for a target. The names returned
are suitable for passing to the set_source_files_properties command.
SOVERSION
What version number is this target.
For shared libraries VERSION and SOVERSION can be used to specify the
build version and api version respectively. When building or
installing appropriate symlinks are created if the platform supports
symlinks and the linker supports so-names. If only one of both is
specified the missing is assumed to have the same version number. For
shared libraries and executables on Windows the VERSION attribute is
parsed to extract a "major.minor" version number. These numbers are
used as the image version of the binary.
STATIC_LIBRARY_FLAGS
Extra flags to use when linking static libraries.
Extra flags to use when linking a static library.
SUFFIX
What comes after the library name.
A target property that can be set to override the suffix (such as
".so") on a library name.
TYPE
The type of the target.
This read-only property can be used to test the type of the given
target. It will be one of STATIC_LIBRARY, MODULE_LIBRARY,
SHARED_LIBRARY, EXECUTABLE or one of the internal target types.
VERSION
What version number is this target.
For shared libraries VERSION and SOVERSION can be used to specify the
build version and api version respectively. When building or
installing appropriate symlinks are created if the platform supports
symlinks and the linker supports so-names. If only one of both is
specified the missing is assumed to have the same version number. For
executables VERSION can be used to specify the build version. When
building or installing appropriate symlinks are created if the
platform supports symlinks. For shared libraries and executables on
Windows the VERSION attribute is parsed to extract a "major.minor"
version number. These numbers are used as the image version of the
binary.
VS_KEYWORD
Visual Studio project keyword.
Can be set to change the visual studio keyword, for example QT
integration works better if this is set to Qt4VSv1.0.
VS_SCC_LOCALPATH
Visual Studio Source Code Control Provider.
Can be set to change the visual studio source code control local path
property.
VS_SCC_PROJECTNAME
Visual Studio Source Code Control Project.
Can be set to change the visual studio source code control project
name property.
VS_SCC_PROVIDER
Visual Studio Source Code Control Provider.
Can be set to change the visual studio source code control provider
property.
WIN32_EXECUTABLE
Build an executable with a WinMain entry point on windows.
When this property is set to true the executable when linked on
Windows will be created with a WinMain() entry point instead of of
just main().This makes it a GUI executable instead of a console
application. See the CMAKE_MFC_FLAG variable documentation to
configure use of MFC for WinMain executables.
XCODE_ATTRIBUTE_<an-attribute>
Set Xcode target attributes directly.
Tell the Xcode generator to set '<an-attribute>' to a given value in
the generated Xcode project. Ignored on other generators.
------------------------------------------------------------------------------
Properties on Tests
ENVIRONMENT
Specify environment variables that should be defined for running a
test.
If set to a list of environment variables and values of the form
MYVAR=value those environment variables will be defined while running
the test. The environment is restored to its previous state after the
test is done.
FAIL_REGULAR_EXPRESSION
If the output matches this regular expression the test will fail.
If set, if the output matches one of specified regular expressions,
the test will fail.For example: PASS_REGULAR_EXPRESSION
"[^a-z]Error;ERROR;Failed"
LABELS
Specify a list of text labels associated with a test.
The list is reported in dashboard submissions.
MEASUREMENT
Specify a CDASH measurement and value to be reported for a test.
If set to a name then that name will be reported to CDASH as a named
measurement with a value of 1. You may also specify a value by
setting MEASUREMENT to "measurement=value".
PASS_REGULAR_EXPRESSION
The output must match this regular expression for the test to pass.
If set, the test output will be checked against the specified regular
expressions and at least one of the regular expressions has to match,
otherwise the test will fail.
TIMEOUT
How many seconds to allow for this test.
This property if set will limit a test to not take more than the
specified number of seconds to run. If it exceeds that the test
process will be killed and ctest will move to the next test. This
setting takes precedence over CTEST_TESTING_TIMEOUT.
WILL_FAIL
If set to true, this will invert the pass/fail flag of the test.
This property can be used for tests that are expected to fail and
return a non zero return code.
------------------------------------------------------------------------------
Properties on Source Files
ABSTRACT
Is this source file an abstract class.
A property on a source file that indicates if the source file
represents a class that is abstract. This only makes sense for
languages that have a notion of an abstract class and it is only used
by some tools that wrap classes into other languages.
COMPILE_DEFINITIONS
Preprocessor definitions for compiling a source file.
The COMPILE_DEFINITIONS property may be set to a semicolon-separated
list of preprocessor definitions using the syntax VAR or VAR=value.
Function-style definitions are not supported. CMake will
automatically escape the value correctly for the native build system
(note that CMake language syntax may require escapes to specify some
values). This property may be set on a per-configuration basis using
the name COMPILE_DEFINITIONS_<CONFIG> where <CONFIG> is an upper-case
name (ex. "COMPILE_DEFINITIONS_DEBUG").
CMake will automatically drop some definitions that are not supported
by the native build tool. The VS6 IDE does not support definition
values with spaces (but NMake does). Xcode does not support
per-configuration definitions on source files.
Dislaimer: Most native build tools have poor support for escaping
certain values. CMake has work-arounds for many cases but some values
may just not be possible to pass correctly. If a value does not seem
to be escaped correctly, do not attempt to work-around the problem by
adding escape sequences to the value. Your work-around may break in a
future version of CMake that has improved escape support. Instead
consider defining the macro in a (configured) header file. Then
report the limitation.
COMPILE_DEFINITIONS_<CONFIG>
Per-configuration preprocessor definitions on a source file.
This is the configuration-specific version of COMPILE_DEFINITIONS.
Note that Xcode does not support per-configuration source file flags
so this property will be ignored by the Xcode generator.
COMPILE_FLAGS
Additional flags to be added when compiling this source file.
These flags will be added to the list of compile flags when this
source file builds. Use COMPILE_DEFINITIONS to pass additional
preprocessor definitions.
EXTERNAL_OBJECT
If set to true then this is an object file.
If this property is set to true then the source file is really an
object file and should not be compiled. It will still be linked into
the target though.
GENERATED
Is this source file generated as part of the build process.
If a source file is generated by the build process CMake will handle
it differently in temrs of dependency checking etc. Otherwise having
a non-existent source file could create problems.
HEADER_FILE_ONLY
Is this source file only a header file.
A property on a source file that indicates if the source file is a
header file with no associated implementation. This is set
automatically based on the file extension and is used by CMake to
determine is certain dependency information should be computed.
KEEP_EXTENSION
Make the output file have the same extension as the source file.
If this property is set then the file extension of the output file
will be the same as that of the source file. Normally the output file
extension is computed based on the language of the source file, for
example .cxx will go to a .o extension.
LABELS
Specify a list of text labels associated with a source file.
This property has meaning only when the source file is listed in a
target whose LABELS property is also set. No other semantics are
currently specified.
LANGUAGE
What programming language is the file.
A property that can be set to indicate what programming language the
source file is. If it is not set the language is determined based on
the file extension. Typical values are CXX C etc.
LOCATION
The full path to a source file.
A read only property on a SOURCE FILE that contains the full path to
the source file.
MACOSX_PACKAGE_LOCATION
Place a source file inside a Mac OS X bundle or framework.
Executable targets with the MACOSX_BUNDLE property set are built as
Mac OS X application bundles on Apple platforms. Shared library
targets with the FRAMEWORK property set are built as Mac OS X
frameworks on Apple platforms. Source files listed in the target with
this property set will be copied to a directory inside the bundle or
framework content folder specified by the property value. For bundles
the content folder is "<name>.app/Contents". For frameworks the
content folder is "<name>.framework/Versions/<version>". See the
PUBLIC_HEADER, PRIVATE_HEADER, and RESOURCE target properties for
specifying files meant for Headers, PrivateHeadres, or Resources
directories.
OBJECT_DEPENDS
Additional files on which a compiled object file depends.
Specifies a semicolon-separated list of full-paths to files on which
any object files compiled from this source file depend. An object
file will be recompiled if any of the named files is newer than it.
This property need not be used to specify the dependency of a source
file on a generated header file that it includes. Although the
property was originally introduced for this purpose, it is no longer
necessary. If the generated header file is created by a custom
command in the same target as the source file, the automatic
dependency scanning process will recognize the dependency. If the
generated header file is created by another target, an inter-target
dependency should be created with the add_dependencies command (if one
does not already exist due to linking relationships).
OBJECT_OUTPUTS
Additional outputs for a Makefile rule.
Additional outputs created by compilation of this source file. If any
of these outputs is missing the object will be recompiled. This is
supported only on Makefile generators and will be ignored on other
generators.
SYMBOLIC
Is this just a name for a rule.
If SYMBOLIC (boolean) is set to true the build system will be informed
that the source file is not actually created on disk but instead used
as a symbolic name for a build rule.
WRAP_EXCLUDE
Exclude this source file from any code wrapping techniques.
Some packages can wrap source files into alternate languages to
provide additional functionality. For example, C++ code can be
wrapped into Java or Python etc using SWIG etc. If WRAP_EXCLUDE is
set to true (1 etc) that indicates then this source file should not be
wrapped.
------------------------------------------------------------------------------
Properties on Cache Entries
ADVANCED
True if entry should be hidden by default in GUIs.
This is a boolean value indicating whether the entry is considered
interesting only for advanced configuration. The mark_as_advanced()
command modifies this property.
HELPSTRING
Help associated with entry in GUIs.
This string summarizes the purpose of an entry to help users set it
through a CMake GUI.
MODIFIED
Internal management property. Do not set or get.
This is an internal cache entry property managed by CMake to track
interactive user modification of entries. Ignore it.
STRINGS
Enumerate possible STRING entry values for GUI selection.
For cache entries with type STRING, this enumerates a set of values.
CMake GUIs may use this to provide a selection widget instead of a
generic string entry field. This is for convenience only. CMake does
not enforce that the value matches one of those listed.
TYPE
Widget type for entry in GUIs.
Cache entry values are always strings, but CMake GUIs present widgets
to help users set values. The GUIs use this property as a hint to
determine the widget type. Valid TYPE values are:
BOOL = Boolean ON/OFF value.
PATH = Path to a directory.
FILEPATH = Path to a file.
STRING = Generic string value.
INTERNAL = Do not present in GUI at all.
STATIC = Value managed by CMake, do not change.
UNINITIALIZED = Type not yet specified.
Generally the TYPE of a cache entry should be set by the command which
creates it (set, option, find_library, etc.).
VALUE
Value of a cache entry.
This property maps to the actual value of a cache entry. Setting this
property always sets the value without checking, so use with care.
------------------------------------------------------------------------------
Compatibility Commands
CMake Compatibility Listfile Commands - Obsolete commands supported by CMake for compatibility.
This is the documentation for now obsolete listfile commands from previous
CMake versions, which are still supported for compatibility reasons. You
should instead use the newer, faster and shinier new commands. ;-)
------------------------------------------------------------------------------
Compatilbility Commands
build_name
Deprecated. Use ${CMAKE_SYSTEM} and ${CMAKE_CXX_COMPILER} instead.
build_name(variable)
Sets the specified variable to a string representing the platform and
compiler settings. These values are now available through the
CMAKE_SYSTEM and CMAKE_CXX_COMPILER variables.
exec_program
Deprecated. Use the execute_process() command instead.
Run an executable program during the processing of the CMakeList.txt
file.
exec_program(Executable [directory in which to run]
[ARGS <arguments to executable>]
[OUTPUT_VARIABLE <var>]
[RETURN_VALUE <var>])
The executable is run in the optionally specified directory. The
executable can include arguments if it is double quoted, but it is
better to use the optional ARGS argument to specify arguments to the
program. This is because cmake will then be able to escape spaces in
the executable path. An optional argument OUTPUT_VARIABLE specifies a
variable in which to store the output. To capture the return value of
the execution, provide a RETURN_VALUE. If OUTPUT_VARIABLE is
specified, then no output will go to the stdout/stderr of the console
running cmake.
export_library_dependencies
Deprecated. Use INSTALL(EXPORT) or EXPORT command.
This command generates an old-style library dependencies file.
Projects requiring CMake 2.6 or later should not use the command. Use
instead the install(EXPORT) command to help export targets from an
installation tree and the export() command to export targets from a
build tree.
The old-style library dependencies file does not take into account
per-configuration names of libraries or the LINK_INTERFACE_LIBRARIES
target property.
export_library_dependencies(<file> [APPEND])
Create a file named <file> that can be included into a CMake listfile
with the INCLUDE command. The file will contain a number of SET
commands that will set all the variables needed for library dependency
information. This should be the last command in the top level
CMakeLists.txt file of the project. If the APPEND option is
specified, the SET commands will be appended to the given file instead
of replacing it.
install_files
Deprecated. Use the install(FILES ) command instead.
This command has been superceded by the install command. It is
provided for compatibility with older CMake code. The FILES form is
directly replaced by the FILES form of the install command. The
regexp form can be expressed more clearly using the GLOB form of the
file command.
install_files(<dir> extension file file ...)
Create rules to install the listed files with the given extension into
the given directory. Only files existing in the current source tree
or its corresponding location in the binary tree may be listed. If a
file specified already has an extension, that extension will be
removed first. This is useful for providing lists of source files
such as foo.cxx when you want the corresponding foo.h to be installed.
A typical extension is '.h'.
install_files(<dir> regexp)
Any files in the current source directory that match the regular
expression will be installed.
install_files(<dir> FILES file file ...)
Any files listed after the FILES keyword will be installed explicitly
from the names given. Full paths are allowed in this form.
The directory <dir> is relative to the installation prefix, which is
stored in the variable CMAKE_INSTALL_PREFIX.
install_programs
Deprecated. Use the install(PROGRAMS ) command instead.
This command has been superceded by the install command. It is
provided for compatibility with older CMake code. The FILES form is
directly replaced by the PROGRAMS form of the INSTALL command. The
regexp form can be expressed more clearly using the GLOB form of the
FILE command.
install_programs(<dir> file1 file2 [file3 ...])
install_programs(<dir> FILES file1 [file2 ...])
Create rules to install the listed programs into the given directory.
Use the FILES argument to guarantee that the file list version of the
command will be used even when there is only one argument.
install_programs(<dir> regexp)
In the second form any program in the current source directory that
matches the regular expression will be installed.
This command is intended to install programs that are not built by
cmake, such as shell scripts. See the TARGETS form of the INSTALL
command to create installation rules for targets built by cmake.
The directory <dir> is relative to the installation prefix, which is
stored in the variable CMAKE_INSTALL_PREFIX.
install_targets
Deprecated. Use the install(TARGETS ) command instead.
This command has been superceded by the install command. It is
provided for compatibility with older CMake code.
install_targets(<dir> [RUNTIME_DIRECTORY dir] target target)
Create rules to install the listed targets into the given directory.
The directory <dir> is relative to the installation prefix, which is
stored in the variable CMAKE_INSTALL_PREFIX. If RUNTIME_DIRECTORY is
specified, then on systems with special runtime files (Windows DLL),
the files will be copied to that directory.
link_libraries
Deprecated. Use the target_link_libraries() command instead.
Link libraries to all targets added later.
link_libraries(library1 <debug | optimized> library2 ...)
Specify a list of libraries to be linked into any following targets
(typically added with the add_executable or add_library calls). This
command is passed down to all subdirectories. The debug and optimized
strings may be used to indicate that the next library listed is to be
used only for that specific type of build.
make_directory
Deprecated. Use the file(MAKE_DIRECTORY ) command instead.
make_directory(directory)
Creates the specified directory. Full paths should be given. Any
parent directories that do not exist will also be created. Use with
care.
remove
Deprecated. Use the list(REMOVE_ITEM ) command instead.
remove(VAR VALUE VALUE ...)
Removes VALUE from the variable VAR. This is typically used to remove
entries from a vector (e.g. semicolon separated list). VALUE is
expanded.
subdir_depends
Deprecated. Does nothing.
subdir_depends(subdir dep1 dep2 ...)
Does not do anything. This command used to help projects order
parallel builds correctly. This functionality is now automatic.
subdirs
Deprecated. Use the add_subdirectory() command instead.
Add a list of subdirectories to the build.
subdirs(dir1 dir2 ...[EXCLUDE_FROM_ALL exclude_dir1 exclude_dir2 ...]
[PREORDER] )
Add a list of subdirectories to the build. The add_subdirectory
command should be used instead of subdirs although subdirs will still
work. This will cause any CMakeLists.txt files in the sub directories
to be processed by CMake. Any directories after the PREORDER flag are
traversed first by makefile builds, the PREORDER flag has no effect on
IDE projects. Any directories after the EXCLUDE_FROM_ALL marker will
not be included in the top level makefile or project file. This is
useful for having CMake create makefiles or projects for a set of
examples in a project. You would want CMake to generate makefiles or
project files for all the examples at the same time, but you would not
want them to show up in the top level project or be built each time
make is run from the top.
use_mangled_mesa
Copy mesa headers for use in combination with system GL.
use_mangled_mesa(PATH_TO_MESA OUTPUT_DIRECTORY)
The path to mesa includes, should contain gl_mangle.h. The mesa
headers are copied to the specified output directory. This allows
mangled mesa headers to override other GL headers by being added to
the include directory path earlier.
utility_source
Specify the source tree of a third-party utility.
utility_source(cache_entry executable_name
path_to_source [file1 file2 ...])
When a third-party utility's source is included in the distribution,
this command specifies its location and name. The cache entry will
not be set unless the path_to_source and all listed files exist. It
is assumed that the source tree of the utility will have been built
before it is needed.
When cross compiling CMake will print a warning if a utility_source()
command is executed, because in many cases it is used to build an
executable which is executed later on. This doesn't work when cross
compiling, since the executable can run only on their target platform.
So in this case the cache entry has to be adjusted manually so it
points to an executable which is runnable on the build host.
variable_requires
Deprecated. Use the if() command instead.
Assert satisfaction of an option's required variables.
variable_requires(TEST_VARIABLE RESULT_VARIABLE
REQUIRED_VARIABLE1
REQUIRED_VARIABLE2 ...)
The first argument (TEST_VARIABLE) is the name of the variable to be
tested, if that variable is false nothing else is done. If
TEST_VARIABLE is true, then the next argument (RESULT_VARIABLE) is a
variable that is set to true if all the required variables are set.
The rest of the arguments are variables that must be true or not set
to NOTFOUND to avoid an error. If any are not true, an error is
reported.
write_file
Deprecated. Use the file(WRITE ) command instead.
write_file(filename "message to write"... [APPEND])
The first argument is the file name, the rest of the arguments are
messages to write. If the argument APPEND is specified, then the
message will be appended.
NOTE 1: file(WRITE ... and file(APPEND ... do exactly the same as
this one but add some more functionality.
NOTE 2: When using write_file the produced file cannot be used as an
input to CMake (CONFIGURE_FILE, source file ...) because it will lead
to an infinite loop. Use configure_file if you want to generate input
files to CMake.
------------------------------------------------------------------------------
Standard CMake Modules
The following modules are provided with CMake. They can be used with
INCLUDE(ModuleName).
CMake Modules - Modules coming with CMake, the Cross-Platform Makefile Generator.
This is the documentation for the modules and scripts coming with CMake.
Using these modules you can check the computer system for installed software
packages, features of the compiler and the existance of headers to name just
a few.
AddFileDependencies
ADD_FILE_DEPENDENCIES(source_file depend_files...)
Adds the given files as dependencies to source_file
BundleUtilities
BundleUtilities.cmake
A collection of CMake utility functions useful for dealing with .app
bundles on the Mac and bundle-like directories on any OS.
The following functions are provided by this script:
get_bundle_main_executable
get_dotapp_dir
get_bundle_and_executable
get_bundle_all_executables
get_item_key
clear_bundle_keys
set_bundle_key_values
get_bundle_keys
copy_resolved_item_into_bundle
fixup_bundle_item
fixup_bundle
copy_and_fixup_bundle
verify_bundle_prerequisites
verify_bundle_symlinks
verify_app
Requires CMake 2.6 or greater because it uses function, break and
PARENT_SCOPE. Also depends on GetPrerequisites.cmake.
CMakeBackwardCompatibilityCXX
define a bunch of backwards compatibility variables
CMAKE_ANSI_CXXFLAGS - flag for ansi c++
CMAKE_HAS_ANSI_STRING_STREAM - has <strstream>
INCLUDE(TestForANSIStreamHeaders)
INCLUDE(CheckIncludeFileCXX)
INCLUDE(TestForSTDNamespace)
INCLUDE(TestForANSIForScope)
CMakeDependentOption
Macro to provide an option dependent on other options.
This macro presents an option to the user only if a set of other
conditions are true. When the option is not presented a default value
is used, but any value set by the user is preserved for when the
option is presented again. Example invocation:
CMAKE_DEPENDENT_OPTION(USE_FOO "Use Foo" ON
"USE_BAR;NOT USE_ZOT" OFF)
If USE_BAR is true and USE_ZOT is false, this provides an option
called USE_FOO that defaults to ON. Otherwise, it sets USE_FOO to
OFF. If the status of USE_BAR or USE_ZOT ever changes, any value for
the USE_FOO option is saved so that when the option is re-enabled it
retains its old value.
CMakeDetermineVSServicePack
Includes a public function for assisting users in trying to determine
the
Visual Studio service pack in use.
Sets the passed in variable to one of the following values or an empty
string if unknown.
vc80
vc80sp1
vc90
vc90sp1
Usage: ===========================
if(MSVC)
include(CMakeDetermineVSServicePack)
DetermineVSServicePack( my_service_pack )
if( my_service_pack )
message(STATUS "Detected: ${my_service_pack}")
endif()
endif()
===========================
CMakeFindFrameworks
helper module to find OSX frameworks
CMakeForceCompiler
This module defines macros intended for use by cross-compiling
toolchain files when CMake is not able to automatically detect the
compiler identification.
Macro CMAKE_FORCE_C_COMPILER has the following signature:
CMAKE_FORCE_C_COMPILER(<compiler> <compiler-id>)
It sets CMAKE_C_COMPILER to the given compiler and the cmake internal
variable CMAKE_C_COMPILER_ID to the given compiler-id. It also
bypasses the check for working compiler and basic compiler information
tests.
Macro CMAKE_FORCE_CXX_COMPILER has the following signature:
CMAKE_FORCE_CXX_COMPILER(<compiler> <compiler-id>)
It sets CMAKE_CXX_COMPILER to the given compiler and the cmake
internal variable CMAKE_CXX_COMPILER_ID to the given compiler-id. It
also bypasses the check for working compiler and basic compiler
information tests.
So a simple toolchain file could look like this:
INCLUDE (CMakeForceCompiler)
SET(CMAKE_SYSTEM_NAME Generic)
CMAKE_FORCE_C_COMPILER (chc12 MetrowerksHicross)
CMAKE_FORCE_CXX_COMPILER (chc12 MetrowerksHicross)
CMakePrintSystemInformation
print system information
This file can be used for diagnostic purposes just include it in a
project to see various internal CMake variables.
CMakeVerifyManifest
CMakeVerifyManifest.cmake
This script is used to verify that embeded manifests and side by side
manifests for a project match. To run this script, cd to a directory
and run the script with cmake -P. On the command line you can pass in
versions that are OK even if not found in the .manifest files. For
example, cmake -Dallow_versions=8.0.50608.0
-PCmakeVerifyManifest.cmake could be used to allow an embeded manifest
of 8.0.50608.0 to be used in a project even if that version was not
found in the .manifest file.
CPack
Build binary and source package installers
The CPack module generates binary and source installers in a variety
of formats using the cpack program. Inclusion of the CPack module
adds two new targets to the resulting makefiles, package and
package_source, which build the binary and source installers,
respectively. The generated binary installers contain everything
installed via CMake's INSTALL command (and the deprecated
INSTALL_FILES, INSTALL_PROGRAMS, and INSTALL_TARGETS commands).
For certain kinds of binary installers (including the graphical
installers on Mac OS X and Windows), CPack generates installers that
allow users to select individual application components to install.
The contents of each of the components are identified by the COMPONENT
argument of CMake's INSTALL command. These components can be
annotated with user-friendly names and descriptions, inter-component
dependencies, etc., and grouped in various ways to customize the
resulting installer. See the cpack_add_* commands, described below,
for more information about component-specific installations.
Before including the CPack module, there are a variety of variables
that can be set to customize the resulting installers. The most
commonly-used variables are:
CPACK_PACKAGE_NAME - The name of the package (or application). If
not specified, defaults to the project name.
CPACK_PACKAGE_VENDOR - The name of the package vendor (e.g.,
"Kitware").
CPACK_PACKAGE_VERSION_MAJOR - Package major Version
CPACK_PACKAGE_VERSION_MINOR - Package minor Version
CPACK_PACKAGE_VERSION_PATCH - Package patch Version
CPACK_PACKAGE_DESCRIPTION_FILE - A text file used to describe the
project. Used, for example, the introduction screen of a
CPack-generated Windows installer to describe the project.
CPACK_PACKAGE_DESCRIPTION_SUMMARY - Short description of the
project (only a few words).
CPACK_PACKAGE_FILE_NAME - The name of the package file to generate,
not including the extension. For example, cmake-2.6.1-Linux-i686.
CPACK_PACKAGE_INSTALL_DIRECTORY - Installation directory on the
target system, e.g., "CMake 2.5".
CPACK_RESOURCE_FILE_LICENSE - License file for the project, which
will typically be displayed to the user (often with an explicit
"Accept" button, for graphical installers) prior to installation.
CPACK_RESOURCE_FILE_README - ReadMe file for the project, which
typically describes in some detail
CPACK_RESOURCE_FILE_WELCOME - Welcome file for the project, which
welcomes users to this installer. Typically used in the graphical
installers on Windows and Mac OS X.
CPACK_MONOLITHIC_INSTALL - Disables the component-based
installation mechanism, so that all components are always installed.
CPACK_GENERATOR - List of CPack generators to use. If not
specified, CPack will create a set of options (e.g.,
CPACK_BINARY_NSIS) allowing the user to enable/disable individual
generators.
CPACK_OUTPUT_CONFIG_FILE - The name of the CPack configuration file
for binary installers that will be generated by the CPack
module. Defaults to CPackConfig.cmake.
CPACK_PACKAGE_EXECUTABLES - Lists each of the executables along
with a text label, to be used to create Start Menu shortcuts on
Windows. For example, setting this to the list ccmake;CMake will
create a shortcut named "CMake" that will execute the installed
executable ccmake.
CPACK_STRIP_FILES - List of files to be stripped. Starting with
CMake 2.6.0 CPACK_STRIP_FILES will be a boolean variable which
enables stripping of all files (a list of files evaluates to TRUE
in CMake, so this change is compatible).
The following CPack variables are specific to source packages, and
will not affect binary packages:
CPACK_SOURCE_PACKAGE_FILE_NAME - The name of the source package,
e.g., cmake-2.6.1
CPACK_SOURCE_STRIP_FILES - List of files in the source tree that
will be stripped. Starting with CMake 2.6.0
CPACK_SOURCE_STRIP_FILES will be a boolean variable which enables
stripping of all files (a list of files evaluates to TRUE in CMake,
so this change is compatible).
CPACK_SOURCE_GENERATOR - List of generators used for the source
packages. As with CPACK_GENERATOR, if this is not specified then
CPack will create a set of options (e.g., CPACK_SOURCE_ZIP)
allowing users to select which packages will be generated.
CPACK_SOURCE_OUTPUT_CONFIG_FILE - The name of the CPack
configuration file for source installers that will be generated by
the CPack module. Defaults to CPackSourceConfig.cmake.
CPACK_SOURCE_IGNORE_FILES - Pattern of files in the source tree
that won't be packaged when building a source package. This is a
list of patterns, e.g., /CVS/;/\\.svn/;\\.swp$;\\.#;/#;.*~;cscope.*
The following variables are specific to the graphical installers built
on Windows using the Nullsoft Installation System.
CPACK_PACKAGE_INSTALL_REGISTRY_KEY - Registry key used when
installing this project.
CPACK_NSIS_MUI_ICON - The icon file (.ico) for the generated
install program.
CPACK_NSIS_MUI_UNIICON - The icon file (.ico) for the generated
uninstall program.
CPACK_PACKAGE_ICON - A branding image that will be displayed inside
the installer.
CPACK_NSIS_EXTRA_INSTALL_COMMANDS - Extra NSIS commands that will
be added to the install Section.
CPACK_NSIS_EXTRA_UNINSTALL_COMMANDS - Extra NSIS commands that will
be added to the uninstall Section.
CPACK_NSIS_COMPRESSOR - The arguments that will be passed to the
NSIS SetCompressor command.
CPACK_NSIS_MODIFY_PATH - If this is set to "ON", then an extra page
will appear in the installer that will allow the user to choose
whether the program directory should be added to the system PATH
variable.
CPACK_NSIS_DISPLAY_NAME - The display name string that appears in
the Windows Add/Remove Program control panel
CPACK_NSIS_PACKAGE_NAME - The title displayed at the top of the
installer.
CPACK_NSIS_INSTALLED_ICON_NAME - A path to the executable that
contains the installer icon.
CPACK_NSIS_HELP_LINK - URL to a web site providing assistance in
installing your application.
CPACK_NSIS_URL_INFO_ABOUT - URL to a web site providing more
information about your application.
CPACK_NSIS_CONTACT - Contact information for questions and comments
about the installation process.
CPACK_NSIS_CREATE_ICONS_EXTRA - Additional NSIS commands for
creating start menu shortcuts.
CPACK_NSIS_DELETE_ICONS_EXTRA -Additional NSIS commands to
uninstall start menu shortcuts.
The following variable is specific to installers build on Mac OS X
using PackageMaker:
CPACK_OSX_PACKAGE_VERSION - The version of Mac OS X that the
resulting PackageMaker archive should be compatible
with. Different versions of Mac OS X support different
features. For example, CPack can only build component-based
installers for Mac OS X 10.4 or newer, and can only build
installers that download component son-the-fly for Mac OS X 10.5
or newer. If left blank, this value will be set to the minimum
version of Mac OS X that supports the requested features. Set this
variable to some value (e.g., 10.4) only if you want to guarantee
that your installer will work on that version of Mac OS X, and
don't mind missing extra features available in the installer
shipping with later versions of Mac OS X.
The following variables are for advanced uses of CPack:
CPACK_CMAKE_GENERATOR - What CMake generator should be used if the
project is CMake project. Defaults to the value of CMAKE_GENERATOR;
few users will want to change this setting.
CPACK_INSTALL_CMAKE_PROJECTS - List of four values that specify
what project to install. The four values are: Build directory,
Project Name, Project Component, Directory. If omitted, CPack will
build an installer that installers everything.
CPACK_SYSTEM_NAME - System name, defaults to the value of
${CMAKE_SYSTEM_NAME}.
CPACK_PACKAGE_VERSION - Package full version, used internally. By
default, this is built from CPACK_PACKAGE_VERSION_MAJOR,
CPACK_PACKAGE_VERSION_MINOR, and CPACK_PACKAGE_VERSION_PATCH.
CPACK_TOPLEVEL_TAG - Directory for the installed files.
CPACK_INSTALL_COMMANDS - Extra commands to install components.
CPACK_INSTALL_DIRECTORIES - Extra directories to install.
Component-specific installation allows users to select specific sets
of components to install during the install process. Installation
components are identified by the COMPONENT argument of CMake's INSTALL
commands, and should be further described by the following CPack
commands:
cpack_add_component - Describes a CPack installation component
named by the COMPONENT argument to a CMake INSTALL command.
cpack_add_component(compname
[DISPLAY_NAME name]
[DESCRIPTION description]
[HIDDEN | REQUIRED | DISABLED ]
[GROUP group]
[DEPENDS comp1 comp2 ... ]
[INSTALL_TYPES type1 type2 ... ]
[DOWNLOADED]
[ARCHIVE_FILE filename])
The cmake_add_component command describes an installation
component, which the user can opt to install or remove as part of
the graphical installation process. compname is the name of the
component, as provided to the COMPONENT argument of one or more
CMake INSTALL commands.
DISPLAY_NAME is the displayed name of the component, used in
graphical installers to display the component name. This value can
be any string.
DESCRIPTION is an extended description of the component, used in
graphical installers to give the user additional information about
the component. Descriptions can span multiple lines using "\n" as
the line separator. Typically, these descriptions should be no
more than a few lines long.
HIDDEN indicates that this component will be hidden in the
graphical installer, so that the user cannot directly change
whether it is installed or not.
REQUIRED indicates that this component is required, and therefore
will always be installed. It will be visible in the graphical
installer, but it cannot be unselected. (Typically, required
components are shown greyed out).
DISABLED indicates that this component should be disabled
(unselected) by default. The user is free to select this component
for installation, unless it is also HIDDEN.
DEPENDS lists the components on which this component depends. If
this component is selected, then each of the components listed
must also be selected. The dependency information is encoded
within the installer itself, so that users cannot install
inconsitent sets of components.
GROUP names the component group of which this component is a
part. If not provided, the component will be a standalone
component, not part of any component group. Component groups are
described with the cpack_add_component_group command, detailed
below.
INSTALL_TYPES lists the installation types of which this component
is a part. When one of these installations types is selected, this
component will automatically be selected. Installation types are
described with the cpack_add_install_type command, detailed below.
DOWNLOADED indicates that this component should be downloaded
on-the-fly by the installer, rather than packaged in with the
installer itself. For more information, see the cpack_configure_downloads
command.
ARCHIVE_FILE provides a name for the archive file created by CPack
to be used for downloaded components. If not supplied, CPack will
create a file with some name based on CPACK_PACKAGE_FILE_NAME and
the name of the component. See cpack_configure_downloads for more
information.
cpack_add_component_group - Describes a group of related CPack
installation components.
cpack_add_component_group(groupname
[DISPLAY_NAME name]
[DESCRIPTION description]
[PARENT_GROUP parent]
[EXPANDED]
[BOLD_TITLE])
The cpack_add_component_group describes a group of installation
components, which will be placed together within the listing of
options. Typically, component groups allow the user to
select/deselect all of the components within a single group via a
single group-level option. Use component groups to reduce the
complexity of installers with many options. groupname is an
arbitrary name used to identify the group in the GROUP argument of
the cpack_add_component command, which is used to place a
component in a group. The name of the group must not conflict with
the name of any component.
DISPLAY_NAME is the displayed name of the component group, used in
graphical installers to display the component group name. This
value can be any string.
DESCRIPTION is an extended description of the component group,
used in graphical installers to give the user additional
information about the components within that group. Descriptions
can span multiple lines using "\n" as the line
separator. Typically, these descriptions should be no more than a
few lines long.
PARENT_GROUP, if supplied, names the parent group of this group.
Parent groups are used to establish a hierarchy of groups,
providing an arbitrary hierarchy of groups.
EXPANDED indicates that, by default, the group should show up as
"expanded", so that the user immediately sees all of the
components within the group. Otherwise, the group will initially
show up as a single entry.
BOLD_TITLE indicates that the group title should appear in bold,
to call the user's attention to the group.
cpack_add_install_type - Add a new installation type containing a
set of predefined component selections to the graphical installer.
cpack_add_install_type(typename
[DISPLAY_NAME name])
The cpack_add_install_type command identifies a set of preselected
components that represents a common use case for an
application. For example, a "Developer" install type might include
an application along with its header and library files, while an
"End user" install type might just include the application's
executable. Each component identifies itself with one or more
install types via the INSTALL_TYPES argument to
cpack_add_component.
DISPLAY_NAME is the displayed name of the install type, which will
typically show up in a drop-down box within a graphical
installer. This value can be any string.
cpack_configure_downloads - Configure CPack to download selected
components on-the-fly as part of the installation process.
cpack_configure_downloads(site
[UPLOAD_DIRECTORY dirname]
[ALL]
[ADD_REMOVE|NO_ADD_REMOVE])
The cpack_configure_downloads command configures installation-time
downloads of selected components. For each downloadable component,
CPack will create an archive containing the contents of that
component, which should be uploaded to the given site. When the
user selects that component for installation, the installer will
download and extract the component in place. This feature is
useful for creating small installers that only download the
requested components, saving bandwidth. Additionally, the
installers are small enough that they will be installed as part of
the normal installation process, and the "Change" button in
Windows Add/Remove Programs control panel will allow one to add or
remove parts of the application after the original
installation. On Windows, the downloaded-components functionality
requires the ZipDLL plug-in for NSIS, available at:
http://nsis.sourceforge.net/ZipDLL_plug-in
On Mac OS X, installers that download components on-the-fly can
only be built and installed on system using Mac OS X 10.5 or
later.
The site argument is a URL where the archives for downloadable
components will reside, e.g., http://www.cmake.org/files/2.6.1/installer/
All of the archives produced by CPack should be uploaded to that location.
UPLOAD_DIRECTORY is the local directory where CPack will create the
various archives for each of the components. The contents of this
directory should be uploaded to a location accessible by the URL given
in the site argument. If omitted, CPack will use the directory
CPackUploads inside the CMake binary directory to store the generated
archives.
The ALL flag indicates that all components be downloaded. Otherwise, only
those components explicitly marked as DOWNLOADED or that have a specified
ARCHIVE_FILE will be downloaded. Additionally, the ALL option implies
ADD_REMOVE (unless NO_ADD_REMOVE is specified).
ADD_REMOVE indicates that CPack should install a copy of the installer
that can be called from Windows' Add/Remove Programs dialog (via the
"Modify" button) to change the set of installed components. NO_ADD_REMOVE
turns off this behavior. This option is ignored on Mac OS X.

Documentation
DocumentationVTK.cmake
This file provides support for the VTK documentation framework. It
relies on several tools (Doxygen, Perl, etc).
ExternalProject
Create custom targets to build projects in external trees
The 'ExternalProject_Add' function creates a custom target to drive
download, update/patch, configure, build, install and test steps of an
external project:
ExternalProject_Add(<name> # Name for custom target
[DEPENDS projects...] # Targets on which the project depends
[PREFIX dir] # Root dir for entire project
[LIST_SEPARATOR sep] # Sep to be replaced by ; in cmd lines
[TMP_DIR dir] # Directory to store temporary files
[STAMP_DIR dir] # Directory to store step timestamps
#--Download step--------------
[DOWNLOAD_DIR dir] # Directory to store downloaded files
[DOWNLOAD_COMMAND cmd...] # Command to download source tree
[CVS_REPOSITORY cvsroot] # CVSROOT of CVS repository
[CVS_MODULE mod] # Module to checkout from CVS repo
[CVS_TAG tag] # Tag to checkout from CVS repo
[SVN_REPOSITORY url] # URL of Subversion repo
[SVN_REVISION rev] # Revision to checkout from Subversion repo
[URL /.../src.tgz] # Full path or URL of source
#--Update/Patch step----------
[UPDATE_COMMAND cmd...] # Source work-tree update command
[PATCH_COMMAND cmd...] # Command to patch downloaded source
#--Configure step-------------
[SOURCE_DIR dir] # Source dir to be used for build
[CONFIGURE_COMMAND cmd...] # Build tree configuration command
[CMAKE_COMMAND /.../cmake] # Specify alternative cmake executable
[CMAKE_GENERATOR gen] # Specify generator for native build
[CMAKE_ARGS args...] # Arguments to CMake command line
#--Build step-----------------
[BINARY_DIR dir] # Specify build dir location
[BUILD_COMMAND cmd...] # Command to drive the native build
[BUILD_IN_SOURCE 1] # Use source dir for build dir
#--Install step---------------
[INSTALL_DIR dir] # Installation prefix
[INSTALL_COMMAND cmd...] # Command to drive install after build
#--Test step---------------
[TEST_BEFORE_INSTALL 1] # Add test step executed before install step
[TEST_AFTER_INSTALL 1] # Add test step executed after install step
[TEST_COMMAND cmd...] # Command to drive test
)
The *_DIR options specify directories for the project, with default
directories computed as follows. If the PREFIX option is given to
ExternalProject_Add() or the EP_PREFIX directory property is set, then
an external project is built and installed under the specified prefix:
TMP_DIR = <prefix>/tmp
STAMP_DIR = <prefix>/src/<name>-stamp
DOWNLOAD_DIR = <prefix>/src
SOURCE_DIR = <prefix>/src/<name>
BINARY_DIR = <prefix>/src/<name>-build
INSTALL_DIR = <prefix>
Otherwise, if the EP_BASE directory property is set then components of
an external project are stored under the specified base:
TMP_DIR = <base>/tmp/<name>
STAMP_DIR = <base>/Stamp/<name>
DOWNLOAD_DIR = <base>/Download/<name>
SOURCE_DIR = <base>/Source/<name>
BINARY_DIR = <base>/Build/<name>
INSTALL_DIR = <base>/Install/<name>
If no PREFIX, EP_PREFIX, or EP_BASE is specified then the default is
to set PREFIX to "<name>-prefix". Relative paths are interpreted with
respect to the build directory corresponding to the source directory
in which ExternalProject_Add is invoked.
If SOURCE_DIR is explicitly set to an existing directory the project
will be built from it. Otherwise a download step must be specified
using one of the DOWNLOAD_COMMAND, CVS_*, SVN_*, or URL options. The
URL option may refer locally to a directory or source tarball, or
refer to a remote tarball (e.g. http://.../src.tgz).
The 'ExternalProject_Add_Step' function adds a custom step to an
external project:
ExternalProject_Add_Step(<name> <step> # Names of project and custom step
[COMMAND cmd...] # Command line invoked by this step
[COMMENT "text..."] # Text printed when step executes
[DEPENDEES steps...] # Steps on which this step depends
[DEPENDERS steps...] # Steps that depend on this step
[DEPENDS files...] # Files on which this step depends
[ALWAYS 1] # No stamp file, step always runs
[WORKING_DIRECTORY dir] # Working directory for command
)
The command line, comment, and working directory of every standard and
custom step is processed to replace tokens <SOURCE_DIR>, <BINARY_DIR>,
<INSTALL_DIR>, and <TMP_DIR> with corresponding property values.
The 'ExternalProject_Get_Property' function retrieves external project
target properties:
ExternalProject_Get_Property(<name> [prop1 [prop2 [...]]])
It stores property values in variables of the same name. Property
names correspond to the keyword argument names of
'ExternalProject_Add'.
FeatureSummary
Macros for generating a summary of enabled/disabled features
PRINT_ENABLED_FEATURES()
Print a summary of all enabled features. By default all successfull
FIND_PACKAGE() calls will appear here, except the ones which used the
QUIET keyword. Additional features can be added by appending an entry
to the global ENABLED_FEATURES property. If SET_FEATURE_INFO() is
used for that feature, the output will be much more informative.
PRINT_DISABLED_FEATURES()
Same as PRINT_ENABLED_FEATURES(), but for disabled features. It can
be extended the same way by adding to the global property
DISABLED_FEATURES.
SET_FEATURE_INFO(NAME DESCRIPTION [URL [COMMENT] ] )
Use this macro to set up information about the named feature, which will
then be displayed by PRINT_ENABLED/DISABLED_FEATURES().
Example: SET_FEATURE_INFO(LibXml2 "XML processing library."
"http://xmlsoft.org/")
FindALSA
Find alsa
Find the alsa libraries (asound)
This module defines the following variables:
ALSA_FOUND - True if ALSA_INCLUDE_DIR & ALSA_LIBRARY are found
ALSA_LIBRARIES - Set when ALSA_LIBRARY is found
ALSA_INCLUDE_DIRS - Set when ALSA_INCLUDE_DIR is found
ALSA_INCLUDE_DIR - where to find asoundlib.h, etc.
ALSA_LIBRARY - the asound library

ASPELL_INCLUDE_DIR - the ASPELL include directory
ASPELL_LIBRARIES - The libraries needed to use ASPELL
ASPELL_DEFINITIONS - Compiler switches required for using ASPELL
FindAVIFile
Locate AVIFILE library and include paths
AVIFILE (http://avifile.sourceforge.net/)is a set of libraries for
i386 machines to use various AVI codecs. Support is limited beyond
Linux. Windows provides native AVI support, and so doesn't need this
library. This module defines
AVIFILE_INCLUDE_DIR, where to find avifile.h , etc.
AVIFILE_LIBRARIES, the libraries to link against
AVIFILE_DEFINITIONS, definitions to use when compiling
AVIFILE_FOUND, If false, don't try to use AVIFILE
FindBISON
Find bison executable and provides macros to generate custom build
rules
The module defines the following variables:
BISON_EXECUTABLE - path to the bison program
BISON_VERSION - version of bison
BISON_FOUND - true if the program was found
If bison is found, the module defines the macros:
BISON_TARGET(<Name> <YaccInput> <CodeOutput> [VERBOSE <file>]
[COMPILE_FLAGS <string>])
which will create a custom rule to generate a parser. <YaccInput> is
the path to a yacc file. <CodeOutput> is the name of the source file
generated by bison. A header file is also be generated, and contains
the token list. If COMPILE_FLAGS option is specified, the next
parameter is added in the bison command line. if VERBOSE option is
specified, <file> is created and contains verbose descriptions of the
grammar and parser. The macro defines a set of variables:
BISON_${Name}_DEFINED - true is the macro ran successfully
BISON_${Name}_INPUT - The input source file, an alias for <YaccInput>
BISON_${Name}_OUTPUT_SOURCE - The source file generated by bison
BISON_${Name}_OUTPUT_HEADER - The header file generated by bison
BISON_${Name}_OUTPUTS - The sources files generated by bison
BISON_${Name}_COMPILE_FLAGS - Options used in the bison command line
====================================================================
Example:
find_package(BISON)
BISON_TARGET(MyParser parser.y ${CMAKE_CURRENT_BINARY_DIR}/parser.cpp)
add_executable(Foo main.cpp ${BISON_MyParser_OUTPUTS})
====================================================================
FindBLAS
Find BLAS library
This module finds an installed fortran library that implements the
BLAS linear-algebra interface (see http://www.netlib.org/blas/). The
list of libraries searched for is taken from the autoconf macro file,
acx_blas.m4 (distributed at
http://ac-archive.sourceforge.net/ac-archive/acx_blas.html).
This module sets the following variables:
BLAS_FOUND - set to true if a library implementing the BLAS interface
is found
BLAS_LINKER_FLAGS - uncached list of required linker flags (excluding -l
and -L).
BLAS_LIBRARIES - uncached list of libraries (using full path name) to
link against to use BLAS
BLAS95_LIBRARIES - uncached list of libraries (using full path name)
to link against to use BLAS95 interface
BLAS95_FOUND - set to true if a library implementing the BLAS f95 interface
is found
BLA_STATIC if set on this determines what kind of linkage we do (static)
BLA_VENDOR if set checks only the specified vendor, if not set checks
all the possibilities
BLA_F95 if set on tries to find the f95 interfaces for BLAS/LAPACK
######### ## List of vendors (BLA_VENDOR) valid in this module #
ATLAS, PhiPACK,CXML,DXML,SunPerf,SCSL,SGIMATH,IBMESSL,Intel10_32
(intel mkl v10 32 bit),Intel10_64lp (intel mkl v10 64 bit,lp thread
model, lp64 model), # Intel( older versions of mkl 32 and 64 bit),
ACML,Apple, NAS, Generic C/CXX should be enabled to use Intel mkl
FindBZip2
Try to find BZip2
Once done this will define
BZIP2_FOUND - system has BZip2
BZIP2_INCLUDE_DIR - the BZip2 include directory
BZIP2_LIBRARIES - Link these to use BZip2
BZIP2_DEFINITIONS - Compiler switches required for using BZip2
BZIP2_NEED_PREFIX - this is set if the functions are prefixed with BZ2_
FindBoost
Try to find Boost include dirs and libraries
Usage of this module as follows:
NOTE: Take note of the Boost_ADDITIONAL_VERSIONS variable below. Due
to Boost naming conventions and limitations in CMake this find module
is NOT future safe with respect to Boost version numbers, and may
break.
== Using Header-Only libraries from within Boost: ==
find_package( Boost 1.36.0 )
if(Boost_FOUND)
include_directories(${Boost_INCLUDE_DIRS})
add_executable(foo foo.cc)
endif()
== Using actual libraries from within Boost: ==
set(Boost_USE_STATIC_LIBS ON)
set(Boost_USE_MULTITHREADED ON)
find_package( Boost 1.36.0 COMPONENTS date_time filesystem system ... )
if(Boost_FOUND)
include_directories(${Boost_INCLUDE_DIRS})
add_executable(foo foo.cc)
target_link_libraries(foo ${Boost_LIBRARIES})
endif()
The components list needs to contain actual names of boost libraries
only, such as "date_time" for "libboost_date_time". If you're using
parts of Boost that contain header files only (e.g. foreach) you do
not need to specify COMPONENTS.
You should provide a minimum version number that should be used. If
you provide this version number and specify the REQUIRED attribute,
this module will fail if it can't find the specified or a later
version. If you specify a version number this is automatically put
into the considered list of version numbers and thus doesn't need to
be specified in the Boost_ADDITIONAL_VERSIONS variable (see below).
NOTE for Visual Studio Users:
Automatic linking is used on MSVC & Borland compilers by default when
#including things in Boost. It's important to note that setting
Boost_USE_STATIC_LIBS to OFF is NOT enough to get you dynamic linking,
should you need this feature. Automatic linking typically uses static
libraries with a few exceptions (Boost.Python is one).
Please see the section below near Boost_LIB_DIAGNOSTIC_DEFINITIONS for
more details. Adding a TARGET_LINK_LIBRARIES() as shown in the example
above appears to cause VS to link dynamically if Boost_USE_STATIC_LIBS
gets set to OFF. It is suggested you avoid automatic linking since it
will make your application less portable.
=========== The mess that is Boost_ADDITIONAL_VERSIONS (sorry?)
============
OK, so the Boost_ADDITIONAL_VERSIONS variable can be used to specify a
list of boost version numbers that should be taken into account when
searching for Boost. Unfortunately boost puts the version number into
the actual filename for the libraries, so this variable will certainly
be needed in the future when new Boost versions are released.
Currently this module searches for the following version numbers:
1.33, 1.33.0, 1.33.1, 1.34, 1.34.0, 1.34.1, 1.35, 1.35.0, 1.35.1,
1.36, 1.36.0, 1.36.1, 1.37, 1.37.0, 1.38, 1.38.0, 1.39, 1.39.0, 1.40,
1.40.0
NOTE: If you add a new major 1.x version in Boost_ADDITIONAL_VERSIONS
you should add both 1.x and 1.x.0 as shown above. Official Boost
include directories omit the 3rd version number from include paths if
it is 0 although not all binary Boost releases do so.
SET(Boost_ADDITIONAL_VERSIONS "1.78" "1.78.0" "1.79" "1.79.0")
===================================== =============
========================
Variables used by this module, they can change the default behaviour
and need to be set before calling find_package:
Boost_USE_MULTITHREADED Can be set to OFF to use the non-multithreaded
boost libraries. If not specified, defaults
to ON.
Boost_USE_STATIC_LIBS Can be set to ON to force the use of the static
boost libraries. Defaults to OFF.
Other Variables used by this module which you may want to set.
Boost_ADDITIONAL_VERSIONS A list of version numbers to use for searching
the boost include directory. Please see
the documentation above regarding this
annoying, but necessary variable :(
Boost_DEBUG Set this to TRUE to enable debugging output
of FindBoost.cmake if you are having problems.
Please enable this before filing any bug
reports.
Boost_DETAILED_FAILURE_MSG FindBoost doesn't output detailed information
about why it failed or how to fix the problem
unless this is set to TRUE or the REQUIRED
keyword is specified in find_package().
[Since CMake 2.8.0]
Boost_COMPILER Set this to the compiler suffix used by Boost
(e.g. "-gcc43") if FindBoost has problems finding
the proper Boost installation
These last three variables are available also as environment
variables:
BOOST_ROOT or BOOSTROOT The preferred installation prefix for searching for
Boost. Set this if the module has problems finding
the proper Boost installation.
BOOST_INCLUDEDIR Set this to the include directory of Boost, if the
module has problems finding the proper Boost installation
BOOST_LIBRARYDIR Set this to the lib directory of Boost, if the
module has problems finding the proper Boost installation
Variables defined by this module:
Boost_FOUND System has Boost, this means the include dir was
found, as well as all the libraries specified in
the COMPONENTS list.
Boost_INCLUDE_DIRS Boost include directories: not cached
Boost_INCLUDE_DIR This is almost the same as above, but this one is
cached and may be modified by advanced users
Boost_LIBRARIES Link to these to use the Boost libraries that you
specified: not cached
Boost_LIBRARY_DIRS The path to where the Boost library files are.
Boost_VERSION The version number of the boost libraries that
have been found, same as in version.hpp from Boost
Boost_LIB_VERSION The version number in filename form as
it's appended to the library filenames
Boost_MAJOR_VERSION major version number of boost
Boost_MINOR_VERSION minor version number of boost
Boost_SUBMINOR_VERSION subminor version number of boost
Boost_LIB_DIAGNOSTIC_DEFINITIONS [WIN32 Only] You can call
add_definitions(${Boost_LIB_DIAGNOSTIC_DEFINITIONS})
to have diagnostic information about Boost's
automatic linking outputted during compilation time.
For each component you specify in find_package(), the following
(UPPER-CASE) variables are set. You can use these variables if you
would like to pick and choose components for your targets instead of
just using Boost_LIBRARIES.
Boost_${COMPONENT}_FOUND True IF the Boost library "component" was found.
Boost_${COMPONENT}_LIBRARY Contains the libraries for the specified Boost
"component" (includes debug and optimized keywords
when needed).
FindBullet
Try to find the Bullet physics engine
This module defines the following variables
BULLET_FOUND - Was bullet found
BULLET_INCLUDE_DIRS - the Bullet include directories
BULLET_LIBRARIES - Link to this, by default it includes
all bullet components (Dynamics,
Collision, LinearMath, & SoftBody)
This module accepts the following variables
BULLET_ROOT - Can be set to bullet install path or Windows build path
FindCABLE
Find CABLE
This module finds if CABLE is installed and determines where the
include files and libraries are. This code sets the following
variables:
CABLE the path to the cable executable
CABLE_TCL_LIBRARY the path to the Tcl wrapper library
CABLE_INCLUDE_DIR the path to the include directory
To build Tcl wrappers, you should add shared library and link it to
${CABLE_TCL_LIBRARY}. You should also add ${CABLE_INCLUDE_DIR} as an
include directory.
FindCUDA
Tools for building CUDA C files: libraries and build dependencies.
This script locates the NVIDIA CUDA C tools. It should work on linux,
windows, and mac and should be reasonably up to date with CUDA C
releases.
This script makes use of the standard find_package arguments of
<VERSION>, REQUIRED and QUIET. CUDA_FOUND will report if an
acceptable version of CUDA was found.
The script will prompt the user to specify CUDA_TOOLKIT_ROOT_DIR if
the prefix cannot be determined by the location of nvcc in the system
path and REQUIRED is specified to find_package(). To use a different
installed version of the toolkit set the environment variable
CUDA_BIN_PATH before running cmake (e.g.
CUDA_BIN_PATH=/usr/local/cuda1.0 instead of the default
/usr/local/cuda) or set CUDA_TOOLKIT_ROOT_DIR after configuring. If
you change the value of CUDA_TOOLKIT_ROOT_DIR, various components that
depend on the path will be relocated.
It might be necessary to set CUDA_TOOLKIT_ROOT_DIR manually on certain
platforms, or to use a cuda runtime not installed in the default
location. In newer versions of the toolkit the cuda library is
included with the graphics driver- be sure that the driver version
matches what is needed by the cuda runtime version.
The following variables affect the behavior of the macros in the
script (in alphebetical order). Note that any of these flags can be
changed multiple times in the same directory before calling
CUDA_ADD_EXECUTABLE, CUDA_ADD_LIBRARY, CUDA_COMPILE, CUDA_COMPILE_PTX
or CUDA_WRAP_SRCS.
CUDA_64_BIT_DEVICE_CODE (Default matches host bit size)
-- Set to ON to compile for 64 bit device code, OFF for 32 bit device code.
Note that making this different from the host code when generating object
or C files from CUDA code just won't work, because size_t gets defined by
nvcc in the generated source. If you compile to PTX and then load the
file yourself, you can mix bit sizes between device and host.
CUDA_ATTACH_VS_BUILD_RULE_TO_CUDA_FILE (Default ON)
-- Set to ON if you want the custom build rule to be attached to the source
file in Visual Studio. Turn OFF if you add the same cuda file to multiple
targets.
This allows the user to build the target from the CUDA file; however, bad
things can happen if the CUDA source file is added to multiple targets.
When performing parallel builds it is possible for the custom build
command to be run more than once and in parallel causing cryptic build
errors. VS runs the rules for every source file in the target, and a
source can have only one rule no matter how many projects it is added to.
When the rule is run from multiple targets race conditions can occur on
the generated file. Eventually everything will get built, but if the user
is unaware of this behavior, there may be confusion. It would be nice if
this script could detect the reuse of source files across multiple targets
and turn the option off for the user, but no good solution could be found.
CUDA_BUILD_CUBIN (Default OFF)
-- Set to ON to enable and extra compilation pass with the -cubin option in
Device mode. The output is parsed and register, shared memory usage is
printed during build.
CUDA_BUILD_EMULATION (Default OFF for device mode)
-- Set to ON for Emulation mode. -D_DEVICEEMU is defined for CUDA C files
when CUDA_BUILD_EMULATION is TRUE.
CUDA_GENERATED_OUTPUT_DIR (Default CMAKE_CURRENT_BINARY_DIR)
-- Set to the path you wish to have the generated files placed. If it is
blank output files will be placed in CMAKE_CURRENT_BINARY_DIR.
Intermediate files will always be placed in
CMAKE_CURRENT_BINARY_DIR/CMakeFiles.
CUDA_HOST_COMPILATION_CPP (Default ON)
-- Set to OFF for C compilation of host code.
CUDA_NVCC_FLAGS
CUDA_NVCC_FLAGS_<CONFIG>
-- Additional NVCC command line arguments. NOTE: multiple arguments must be
semi-colon delimited (e.g. --compiler-options;-Wall)
CUDA_PROPAGATE_HOST_FLAGS (Default ON)
-- Set to ON to propagate CMAKE_{C,CXX}_FLAGS and their configuration
dependent counterparts (e.g. CMAKE_C_FLAGS_DEBUG) automatically to the
host compiler through nvcc's -Xcompiler flag. This helps make the
generated host code match the rest of the system better. Sometimes
certain flags give nvcc problems, and this will help you turn the flag
propagation off. This does not affect the flags supplied directly to nvcc
via CUDA_NVCC_FLAGS or through the OPTION flags specified through
CUDA_ADD_LIBRARY, CUDA_ADD_EXECUTABLE, or CUDA_WRAP_SRCS. Flags used for
shared library compilation are not affected by this flag.
CUDA_VERBOSE_BUILD (Default OFF)
-- Set to ON to see all the commands used when building the CUDA file. When
using a Makefile generator the value defaults to VERBOSE (run make
VERBOSE=1 to see output), although setting CUDA_VERBOSE_BUILD to ON will
always print the output.
The script creates the following macros (in alphebetical order):
CUDA_ADD_CUFFT_TO_TARGET( cuda_target )
-- Adds the cufft library to the target (can be any target). Handles whether
you are in emulation mode or not.
CUDA_ADD_CUBLAS_TO_TARGET( cuda_target )
-- Adds the cublas library to the target (can be any target). Handles
whether you are in emulation mode or not.
CUDA_ADD_EXECUTABLE( cuda_target file0 file1 ...
[WIN32] [MACOSX_BUNDLE] [EXCLUDE_FROM_ALL] [OPTIONS ...] )
-- Creates an executable "cuda_target" which is made up of the files
specified. All of the non CUDA C files are compiled using the standard
build rules specified by CMAKE and the cuda files are compiled to object
files using nvcc and the host compiler. In addition CUDA_INCLUDE_DIRS is
added automatically to include_directories(). Standard CMake target calls
can be used on the target after calling this macro
(e.g. set_target_properties and target_link_libraries).
CUDA_ADD_LIBRARY( cuda_target file0 file1 ...
[STATIC | SHARED | MODULE] [EXCLUDE_FROM_ALL] [OPTIONS ...] )
-- Same as CUDA_ADD_EXECUTABLE except that a library is created.
CUDA_BUILD_CLEAN_TARGET()
-- Creates a convience target that deletes all the dependency files
generated. You should make clean after running this target to ensure the
dependency files get regenerated.
CUDA_COMPILE( generated_files file0 file1 ... [STATIC | SHARED | MODULE]
[OPTIONS ...] )
-- Returns a list of generated files from the input source files to be used
with ADD_LIBRARY or ADD_EXECUTABLE.
CUDA_COMPILE_PTX( generated_files file0 file1 ... [OPTIONS ...] )
-- Returns a list of PTX files generated from the input source files.
CUDA_INCLUDE_DIRECTORIES( path0 path1 ... )
-- Sets the directories that should be passed to nvcc
(e.g. nvcc -Ipath0 -Ipath1 ... ). These paths usually contain other .cu
files.
CUDA_WRAP_SRCS ( cuda_target format generated_files file0 file1 ...
[STATIC | SHARED | MODULE] [OPTIONS ...] )
-- This is where all the magic happens. CUDA_ADD_EXECUTABLE,
CUDA_ADD_LIBRARY, CUDA_COMPILE, and CUDA_COMPILE_PTX all call this
function under the hood.
Given the list of files (file0 file1 ... fileN) this macro generates
custom commands that generate either PTX or linkable objects (use "PTX" or
"OBJ" for the format argument to switch). Files that don't end with .cu
or have the HEADER_FILE_ONLY property are ignored.
The arguments passed in after OPTIONS are extra command line options to
give to nvcc. You can also specify per configuration options by
specifying the name of the configuration followed by the options. General
options must preceed configuration specific options. Not all
configurations need to be specified, only the ones provided will be used.
OPTIONS -DFLAG=2 "-DFLAG_OTHER=space in flag"
DEBUG -g
RELEASE --use_fast_math
RELWITHDEBINFO --use_fast_math;-g
MINSIZEREL --use_fast_math
For certain configurations (namely VS generating object files with
CUDA_ATTACH_VS_BUILD_RULE_TO_CUDA_FILE set to ON), no generated file will
be produced for the given cuda file. This is because when you add the
cuda file to Visual Studio it knows that this file produces an object file
and will link in the resulting object file automatically.
This script will also generate a separate cmake script that is used at
build time to invoke nvcc. This is for serveral reasons.
1. nvcc can return negative numbers as return values which confuses
Visual Studio into thinking that the command succeeded. The script now
checks the error codes and produces errors when there was a problem.
2. nvcc has been known to not delete incomplete results when it
encounters problems. This confuses build systems into thinking the
target was generated when in fact an unusable file exists. The script
now deletes the output files if there was an error.
3. By putting all the options that affect the build into a file and then
make the build rule dependent on the file, the output files will be
regenerated when the options change.
This script also looks at optional arguments STATIC, SHARED, or MODULE to
determine when to target the object compilation for a shared library.
BUILD_SHARED_LIBS is ignored in CUDA_WRAP_SRCS, but it is respected in
CUDA_ADD_LIBRARY. On some systems special flags are added for building
objects intended for shared libraries. A preprocessor macro,
<target_name>_EXPORTS is defined when a shared library compilation is
detected.
Flags passed into add_definitions with -D or /D are passed along to nvcc.
The script defines the following variables:
CUDA_VERSION_MAJOR -- The major version of cuda as reported by nvcc.
CUDA_VERSION_MINOR -- The minor version.
CUDA_VERSION
CUDA_VERSION_STRING -- CUDA_VERSION_MAJOR.CUDA_VERSION_MINOR
CUDA_TOOLKIT_ROOT_DIR -- Path to the CUDA Toolkit (defined if not set).
CUDA_SDK_ROOT_DIR -- Path to the CUDA SDK. Use this to find files in the
SDK. This script will not directly support finding
specific libraries or headers, as that isn't
supported by NVIDIA. If you want to change
libraries when the path changes see the
FindCUDA.cmake script for an example of how to clear
these variables. There are also examples of how to
use the CUDA_SDK_ROOT_DIR to locate headers or
libraries, if you so choose (at your own risk).
CUDA_INCLUDE_DIRS -- Include directory for cuda headers. Added automatically
for CUDA_ADD_EXECUTABLE and CUDA_ADD_LIBRARY.
CUDA_LIBRARIES -- Cuda RT library.
CUDA_CUFFT_LIBRARIES -- Device or emulation library for the Cuda FFT
implementation (alternative to:
CUDA_ADD_CUFFT_TO_TARGET macro)
CUDA_CUBLAS_LIBRARIES -- Device or emulation library for the Cuda BLAS
implementation (alterative to:
CUDA_ADD_CUBLAS_TO_TARGET macro).

FindDart
Find DART
This module looks for the dart testing software and sets DART_ROOT to
point to where it found it.
FindDevIL
This module locates the developer's image library.
http://openil.sourceforge.net/
This module sets: IL_LIBRARIES the name of the IL library. These
include the full path to the core DevIL library. This one has to be
linked into the application. ILU_LIBRARIES the name of the ILU
library. Again, the full path. This library is for filters and
effects, not actual loading. It doesn't have to be linked if the
functionality it provides is not used. ILUT_LIBRARIES the name of the
ILUT library. Full path. This part of the library interfaces with
OpenGL. It is not strictly needed in applications. IL_INCLUDE_DIR
where to find the il.h, ilu.h and ilut.h files. IL_FOUND this is set
to TRUE if all the above variables were set. This will be set to
false if ILU or ILUT are not found, even if they are not needed. In
most systems, if one library is found all the others are as well.
That's the way the DevIL developers release it.
FindDoxygen
This module looks for Doxygen and the path to Graphviz's dot
Doxygen is a documentation generation tool. Please see

FindFLEX
Find flex executable and provides a macro to generate custom build
rules
The module defines the following variables:
FLEX_FOUND - true is flex executable is found
FLEX_EXECUTABLE - the path to the flex executable
FLEX_VERSION - the version of flex
FLEX_LIBRARIES - The flex libraries
If flex is found on the system, the module provides the macro:
FLEX_TARGET(Name FlexInput FlexOutput [COMPILE_FLAGS <string>])
which creates a custom command to generate the <FlexOutput> file from
the <FlexInput> file. If COMPILE_FLAGS option is specified, the next
parameter is added to the flex command line. Name is an alias used to
get details of this custom command. Indeed the macro defines the
following variables:
FLEX_${Name}_DEFINED - true is the macro ran successfully
FLEX_${Name}_OUTPUTS - the source file generated by the custom rule, an
alias for FlexOutput
FLEX_${Name}_INPUT - the flex source file, an alias for ${FlexInput}
Flex scanners oftenly use tokens defined by Bison: the code generated
by Flex depends of the header generated by Bison. This module also
defines a macro:
ADD_FLEX_BISON_DEPENDENCY(FlexTarget BisonTarget)
which adds the required dependency between a scanner and a parser
where <FlexTarget> and <BisonTarget> are the first parameters of
respectively FLEX_TARGET and BISON_TARGET macros.
====================================================================
Example:
find_package(BISON)
find_package(FLEX)
BISON_TARGET(MyParser parser.y ${CMAKE_CURRENT_BINARY_DIR}/parser.cpp
FLEX_TARGET(MyScanner lexer.l ${CMAKE_CURRENT_BIANRY_DIR}/lexer.cpp)
ADD_FLEX_BISON_DEPENDENCY(MyScanner MyParser)

FindHDF5
Find HDF5, a library for reading and writing self describing array
data.
This module invokes the HDF5 wrapper compiler that should be installed
alongside HDF5. Depending upon the HDF5 Configuration, the wrapper
compiler is called either h5cc or h5pcc. If this succeeds, the module
will then call the compiler with the -show argument to see what flags
are used when compiling an HDF5 client application.
The module will optionally accept the COMPONENTS argument. If no
COMPONENTS are specified, then the find module will default to finding
only the HDF5 C library. If one or more COMPONENTS are specified, the
module will attempt to find the language bindings for the specified
components. Currently, the only valid components are C and CXX. The
module does not yet support finding the Fortran bindings. If the
COMPONENTS argument is not given, the module will attempt to find only
the C bindings.
On UNIX systems, this module will read the variable
HDF5_USE_STATIC_LIBRARIES to determine whether or not to prefer a
static link to a dynamic link for HDF5 and all of it's dependencies.
To use this feature, make sure that the HDF5_USE_STATIC_LIBRARIES
variable is set before the call to find_package.
To provide the module with a hint about where to find your HDF5
installation, you can set the environment variable HDF5_ROOT. The
Find module will then look in this path when searching for HDF5
executables, paths, and libraries.
In addition to finding the includes and libraries required to compile
an HDF5 client application, this module also makes an effort to find
tools that come with the HDF5 distribution that may be useful for
regression testing.
This module will define the following variables:
HDF5_INCLUDE_DIR - Location of the hdf5 includes
HDF5_DEFINITIONS - Required compiler definitions for HDF5
HDF5_C_LIBRARIES - Required libraries for the HDF5 C bindings.
HDF5_CXX_LIBRARIES - Required libraries for the HDF5 C++ bindings
HDF5_LIBRARIES - Required libraries for all requested bindings
HDF5_FOUND - true if HDF5 was found on the system
HDF5_LIBRARY_DIRS - the full set of library directories
HDF5_IS_PARALLEL - Whether or not HDF5 was found with parallel IO support
HDF5_C_COMPILER_EXECUTABLE - the path to the HDF5 C wrapper compiler

searches for the ImageMagick executable directory. This code defines
the following variables:
ImageMagick_FOUND - TRUE if all components are found.
ImageMagick_EXECUTABLE_DIR - Full path to executables directory.
ImageMagick_<component>_FOUND - TRUE if <component> is found.
ImageMagick_<component>_EXECUTABLE - Full path to <component> executable.

also defined, but not for general use are
MPEG2_mpeg2_LIBRARY, where to find the MPEG2 library.
MPEG2_vo_LIBRARY, where to find the vo library.
FindMPI
Message Passing Interface (MPI) module.
The Message Passing Interface (MPI) is a library used to write
high-performance parallel applications that use message passing, and
is typically deployed on a cluster. MPI is a standard interface
(defined by the MPI forum) for which many implementations are
available. All of these implementations have somewhat different
compilation approaches (different include paths, libraries to link
against, etc.), and this module tries to smooth out those differences.
This module will set the following variables:
MPI_FOUND TRUE if we have found MPI
MPI_COMPILE_FLAGS Compilation flags for MPI programs
MPI_INCLUDE_PATH Include path(s) for MPI header
MPI_LINK_FLAGS Linking flags for MPI programs
MPI_LIBRARY First MPI library to link against (cached)
MPI_EXTRA_LIBRARY Extra MPI libraries to link against (cached)
MPI_LIBRARIES All libraries to link MPI programs against
MPIEXEC Executable for running MPI programs
MPIEXEC_NUMPROC_FLAG Flag to pass to MPIEXEC before giving it the
number of processors to run on
MPIEXEC_PREFLAGS Flags to pass to MPIEXEC directly before the
executable to run.
MPIEXEC_POSTFLAGS Flags to pass to MPIEXEC after all other flags.
This module will attempt to auto-detect these settings, first by
looking for a MPI compiler, which many MPI implementations provide as
a pass-through to the native compiler to simplify the compilation of
MPI programs. The MPI compiler is stored in the cache variable
MPI_COMPILER, and will attempt to look for commonly-named drivers
mpic++, mpicxx, mpiCC, or mpicc. If the compiler driver is found and
recognized, it will be used to set all of the module variables. To
skip this auto-detection, set MPI_LIBRARY and MPI_INCLUDE_PATH in the
CMake cache.
If no compiler driver is found or the compiler driver is not
recognized, this module will then search for common include paths and
library names to try to detect MPI.
If CMake initially finds a different MPI than was intended, and you
want to use the MPI compiler auto-detection for a different MPI
implementation, set MPI_COMPILER to the MPI compiler driver you want
to use (e.g., mpicxx) and then set MPI_LIBRARY to the string
MPI_LIBRARY-NOTFOUND. When you re-configure, auto-detection of MPI
will run again with the newly-specified MPI_COMPILER.
When using MPIEXEC to execute MPI applications, you should typically
use all of the MPIEXEC flags as follows:
${MPIEXEC} ${MPIEXEC_NUMPROC_FLAG} PROCS ${MPIEXEC_PREFLAGS} EXECUTABLE
${MPIEXEC_POSTFLAGS} ARGS
where PROCS is the number of processors on which to execute the
program, EXECUTABLE is the MPI program, and ARGS are the arguments to
pass to the MPI program.

the compiler supports OpenMP, the flags required to compile with
openmp support are set.
The following variables are set:
OpenMP_C_FLAGS - flags to add to the C compiler for OpenMP support
OpenMP_CXX_FLAGS - flags to add to the CXX compiler for OpenMP support

FindOpenSceneGraph
Find OpenSceneGraph
This module searches for the OpenSceneGraph core "osg" library as well
as OpenThreads, and whatever additional COMPONENTS (nodekits) that you
specify.
See http://www.openscenegraph.org
NOTE: To use this module effectively you must either require CMake >=
2.6.3 with cmake_minimum_required(VERSION 2.6.3) or download and place
FindOpenThreads.cmake, Findosg_functions.cmake, Findosg.cmake, and
Find<etc>.cmake files into your CMAKE_MODULE_PATH.
==================================
This module accepts the following variables (note mixed case)
OpenSceneGraph_DEBUG - Enable debugging output
OpenSceneGraph_MARK_AS_ADVANCED - Mark cache variables as advanced
automatically
The following environment variables are also respected for finding the
OSG and it's various components. CMAKE_PREFIX_PATH can also be used
for this (see find_library() CMake documentation).
<MODULE>_DIR (where MODULE is of the form "OSGVOLUME" and there is a FindosgVolume.cmake file)
OSG_DIR
OSGDIR
OSG_ROOT
This module defines the following output variables:
OPENSCENEGRAPH_FOUND - Was the OSG and all of the specified components found?
OPENSCENEGRAPH_VERSION - The version of the OSG which was found
OPENSCENEGRAPH_INCLUDE_DIRS - Where to find the headers
OPENSCENEGRAPH_LIBRARIES - The OSG libraries
================================== Example Usage:
find_package(OpenSceneGraph 2.0.0 REQUIRED osgDB osgUtil)
# libOpenThreads & libosg automatically searched
include_directories(${OPENSCENEGRAPH_INCLUDE_DIRS})
add_executable(foo foo.cc)
target_link_libraries(foo ${OPENSCENEGRAPH_LIBRARIES})
FindOpenThreads
OpenThreads is a C++ based threading library. Its largest userbase
seems to OpenSceneGraph so you might notice I accept OSGDIR as an
environment path. I consider this part of the Findosg* suite used to
find OpenSceneGraph components. Each component is separate and you
must opt in to each module.
Locate OpenThreads This module defines OPENTHREADS_LIBRARY
OPENTHREADS_FOUND, if false, do not try to link to OpenThreads
OPENTHREADS_INCLUDE_DIR, where to find the headers
$OPENTHREADS_DIR is an environment variable that would correspond to
the ./configure --prefix=$OPENTHREADS_DIR used in building osg.

None of the above will be defined unles zlib can be found. PNG
depends on Zlib
FindPackageHandleStandardArgs
FIND_PACKAGE_HANDLE_STANDARD_ARGS(NAME (DEFAULT_MSG|"Custom failure
message") VAR1 ... )
This macro is intended to be used in FindXXX.cmake modules files.
It handles the REQUIRED and QUIET argument to FIND_PACKAGE() and
it also sets the <UPPERCASED_NAME>_FOUND variable.
The package is found if all variables listed are TRUE.
Example:
FIND_PACKAGE_HANDLE_STANDARD_ARGS(LibXml2 DEFAULT_MSG LIBXML2_LIBRARIES LIBXML2_INCLUDE_DIR)
LibXml2 is considered to be found, if both LIBXML2_LIBRARIES and
LIBXML2_INCLUDE_DIR are valid. Then also LIBXML2_FOUND is set to TRUE.
If it is not found and REQUIRED was used, it fails with FATAL_ERROR,
independent whether QUIET was used or not.
If it is found, the location is reported using the VAR1 argument, so
here a message "Found LibXml2: /usr/lib/libxml2.so" will be printed out.
If the second argument is DEFAULT_MSG, the message in the failure case will
be "Could NOT find LibXml2", if you don't like this message you can specify
your own custom failure message there.
FindPackageMessage
FIND_PACKAGE_MESSAGE(<name> "message for user" "find result details")
This macro is intended to be used in FindXXX.cmake modules files. It
will print a message once for each unique find result. This is useful
for telling the user where a package was found. The first argument
specifies the name (XXX) of the package. The second argument
specifies the message to display. The third argument lists details
about the find result so that if they change the message will be
displayed again. The macro also obeys the QUIET argument to the
find_package command.
Example:
IF(X11_FOUND)
FIND_PACKAGE_MESSAGE(X11 "Found X11: ${X11_X11_LIB}"
"[${X11_X11_LIB}][${X11_INCLUDE_DIR}]")
ELSE(X11_FOUND)
...
ENDIF(X11_FOUND)

include files and libraries are. It also determines what the name of
the library is. This code sets the following variables:
PIKE_INCLUDE_PATH = path to where program.h is found
PIKE_EXECUTABLE = full path to the pike binary
FindPkgConfig
a pkg-config module for CMake
Usage:
pkg_check_modules(<PREFIX> [REQUIRED] <MODULE> [<MODULE>]*)
checks for all the given modules
pkg_search_module(<PREFIX> [REQUIRED] <MODULE> [<MODULE>]*)
checks for given modules and uses the first working one
When the 'REQUIRED' argument was set, macros will fail with an error
when module(s) could not be found
It sets the following variables:
PKG_CONFIG_FOUND ... true if pkg-config works on the system
PKG_CONFIG_EXECUTABLE ... pathname of the pkg-config program
<PREFIX>_FOUND ... set to 1 if module(s) exist
For the following variables two sets of values exist; first one is the
common one and has the given PREFIX. The second set contains flags
which are given out when pkgconfig was called with the '--static'
option.
<XPREFIX>_LIBRARIES ... only the libraries (w/o the '-l')
<XPREFIX>_LIBRARY_DIRS ... the paths of the libraries (w/o the '-L')
<XPREFIX>_LDFLAGS ... all required linker flags
<XPREFIX>_LDFLAGS_OTHER ... all other linker flags
<XPREFIX>_INCLUDE_DIRS ... the '-I' preprocessor flags (w/o the '-I')
<XPREFIX>_CFLAGS ... all required cflags
<XPREFIX>_CFLAGS_OTHER ... the other compiler flags
<XPREFIX> = <PREFIX> for common case
<XPREFIX> = <PREFIX>_STATIC for static linking
There are some special variables whose prefix depends on the count of
given modules. When there is only one module, <PREFIX> stays
unchanged. When there are multiple modules, the prefix will be
changed to <PREFIX>_<MODNAME>:
<XPREFIX>_VERSION ... version of the module
<XPREFIX>_PREFIX ... prefix-directory of the module
<XPREFIX>_INCLUDEDIR ... include-dir of the module
<XPREFIX>_LIBDIR ... lib-dir of the module
<XPREFIX> = <PREFIX> when |MODULES| == 1, else
<XPREFIX> = <PREFIX>_<MODNAME>
A <MODULE> parameter can have the following formats:
{MODNAME} ... matches any version
{MODNAME}>={VERSION} ... at least version <VERSION> is required
{MODNAME}={VERSION} ... exactly version <VERSION> is required
{MODNAME}<={VERSION} ... modules must not be newer than <VERSION>
Examples
pkg_check_modules (GLIB2 glib-2.0)
pkg_check_modules (GLIB2 glib-2.0>=2.10)
requires at least version 2.10 of glib2 and defines e.g.
GLIB2_VERSION=2.10.3
pkg_check_modules (FOO glib-2.0>=2.10 gtk+-2.0)
requires both glib2 and gtk2, and defines e.g.
FOO_glib-2.0_VERSION=2.10.3
FOO_gtk+-2.0_VERSION=2.8.20
pkg_check_modules (XRENDER REQUIRED xrender)
defines e.g.:
XRENDER_LIBRARIES=Xrender;X11
XRENDER_STATIC_LIBRARIES=Xrender;X11;pthread;Xau;Xdmcp
pkg_search_module (BAR libxml-2.0 libxml2 libxml>=2)
FindProducer
Though Producer isn't directly part of OpenSceneGraph, its primary
user is OSG so I consider this part of the Findosg* suite used to find
OpenSceneGraph components. You'll notice that I accept OSGDIR as an
environment path.
Each component is separate and you must opt in to each module. You
must also opt into OpenGL (and OpenThreads?) as these modules won't do
it for you. This is to allow you control over your own system piece
by piece in case you need to opt out of certain components or change
the Find behavior for a particular module (perhaps because the default
FindOpenGL.cmake module doesn't work with your system as an example).
If you want to use a more convenient module that includes everything,
use the FindOpenSceneGraph.cmake instead of the Findosg*.cmake
modules.
Locate Producer This module defines PRODUCER_LIBRARY PRODUCER_FOUND,
if false, do not try to link to Producer PRODUCER_INCLUDE_DIR, where
to find the headers
$PRODUCER_DIR is an environment variable that would correspond to the
./configure --prefix=$PRODUCER_DIR used in building osg.

FindPythonInterp
Find python interpreter
This module finds if Python interpreter is installed and determines
where the executables are. This code sets the following variables:
PYTHONINTERP_FOUND - Was the Python executable found
PYTHON_EXECUTABLE - path to the Python interpreter
FindPythonLibs
Find python libraries
This module finds if Python is installed and determines where the
include files and libraries are. It also determines what the name of
the library is. This code sets the following variables:
PYTHONLIBS_FOUND - have the Python libs been found
PYTHON_LIBRARIES - path to the python library
PYTHON_INCLUDE_PATH - path to where Python.h is found (deprecated)
PYTHON_INCLUDE_DIRS - path to where Python.h is found
PYTHON_DEBUG_LIBRARIES - path to the debug library
FindQt
Searches for all installed versions of QT.
This should only be used if your project can work with multiple
versions of QT. If not, you should just directly use FindQt4 or
FindQt3. If multiple versions of QT are found on the machine, then
The user must set the option DESIRED_QT_VERSION to the version they
want to use. If only one version of qt is found on the machine, then
the DESIRED_QT_VERSION is set to that version and the matching FindQt3
or FindQt4 module is included. Once the user sets DESIRED_QT_VERSION,
then the FindQt3 or FindQt4 module is included.
QT_REQUIRED if this is set to TRUE then if CMake can
not find QT4 or QT3 an error is raised
and a message is sent to the user.
DESIRED_QT_VERSION OPTION is created
QT4_INSTALLED is set to TRUE if qt4 is found.
QT3_INSTALLED is set to TRUE if qt3 is found.
FindQt3
Locate Qt include paths and libraries
This module defines:
QT_INCLUDE_DIR - where to find qt.h, etc.
QT_LIBRARIES - the libraries to link against to use Qt.
QT_DEFINITIONS - definitions to use when
compiling code that uses Qt.
QT_FOUND - If false, don't try to use Qt.
If you need the multithreaded version of Qt, set QT_MT_REQUIRED to
TRUE
Also defined, but not for general use are:
QT_MOC_EXECUTABLE, where to find the moc tool.
QT_UIC_EXECUTABLE, where to find the uic tool.
QT_QT_LIBRARY, where to find the Qt library.
QT_QTMAIN_LIBRARY, where to find the qtmain
library. This is only required by Qt3 on Windows.
FindQt4
Find QT 4
This module can be used to find Qt4. The most important issue is that
the Qt4 qmake is available via the system path. This qmake is then
used to detect basically everything else. This module defines a
number of key variables and macros. The variable QT_USE_FILE is set
which is the path to a CMake file that can be included to compile Qt 4
applications and libraries. It sets up the compilation environment
for include directories, preprocessor defines and populates a
QT_LIBRARIES variable.
Typical usage could be something like:
find_package(Qt4 4.4.3 COMPONENTS QtCore QtGui QtXml REQUIRED )
include(${QT_USE_FILE})
add_executable(myexe main.cpp)
target_link_libraries(myexe ${QT_LIBRARIES})
The minimum required version can be specified using the standard
find_package()-syntax (see example above). For compatibility with
older versions of FindQt4.cmake it is also possible to set the
variable QT_MIN_VERSION to the minimum required version of Qt4 before
the find_package(Qt4) command. If both are used, the version used in
the find_package() command overrides the one from QT_MIN_VERSION.
When using the components argument, QT_USE_QT* variables are
automatically set for the QT_USE_FILE to pick up. If one wishes to
manually set them, the available ones to set include:
QT_DONT_USE_QTCORE
QT_DONT_USE_QTGUI
QT_USE_QT3SUPPORT
QT_USE_QTASSISTANT
QT_USE_QAXCONTAINER
QT_USE_QAXSERVER
QT_USE_QTDESIGNER
QT_USE_QTMOTIF
QT_USE_QTMAIN
QT_USE_QTNETWORK
QT_USE_QTNSPLUGIN
QT_USE_QTOPENGL
QT_USE_QTSQL
QT_USE_QTXML
QT_USE_QTSVG
QT_USE_QTTEST
QT_USE_QTUITOOLS
QT_USE_QTDBUS
QT_USE_QTSCRIPT
QT_USE_QTASSISTANTCLIENT
QT_USE_QTHELP
QT_USE_QTWEBKIT
QT_USE_QTXMLPATTERNS
QT_USE_PHONON
QT_USE_QTSCRIPTTOOLS
There are also some files that need processing by some Qt tools such
as moc and uic. Listed below are macros that may be used to process
those files.
macro QT4_WRAP_CPP(outfiles inputfile ... OPTIONS ...)
create moc code from a list of files containing Qt class with
the Q_OBJECT declaration. Per-direcotry preprocessor definitions
are also added. Options may be given to moc, such as those found
when executing "moc -help".
macro QT4_WRAP_UI(outfiles inputfile ... OPTIONS ...)
create code from a list of Qt designer ui files.
Options may be given to uic, such as those found
when executing "uic -help"
macro QT4_ADD_RESOURCES(outfiles inputfile ... OPTIONS ...)
create code from a list of Qt resource files.
Options may be given to rcc, such as those found
when executing "rcc -help"
macro QT4_GENERATE_MOC(inputfile outputfile )
creates a rule to run moc on infile and create outfile.
Use this if for some reason QT4_WRAP_CPP() isn't appropriate, e.g.
because you need a custom filename for the moc file or something similar.
macro QT4_AUTOMOC(sourcefile1 sourcefile2 ... )
This macro is still experimental.
It can be used to have moc automatically handled.
So if you have the files foo.h and foo.cpp, and in foo.h a
a class uses the Q_OBJECT macro, moc has to run on it. If you don't
want to use QT4_WRAP_CPP() (which is reliable and mature), you can insert
#include "foo.moc"
in foo.cpp and then give foo.cpp as argument to QT4_AUTOMOC(). This will the
scan all listed files at cmake-time for such included moc files and if it finds
them cause a rule to be generated to run moc at build time on the
accompanying header file foo.h.
If a source file has the SKIP_AUTOMOC property set it will be ignored by this macro.
macro QT4_ADD_DBUS_INTERFACE(outfiles interface basename)
create a the interface header and implementation files with the
given basename from the given interface xml file and add it to
the list of sources
macro QT4_ADD_DBUS_INTERFACES(outfiles inputfile ... )
create the interface header and implementation files
for all listed interface xml files
the name will be automatically determined from the name of the xml file
macro QT4_ADD_DBUS_ADAPTOR(outfiles xmlfile parentheader parentclassname [basename] [classname])
create a dbus adaptor (header and implementation file) from the xml file
describing the interface, and add it to the list of sources. The adaptor
forwards the calls to a parent class, defined in parentheader and named
parentclassname. The name of the generated files will be
<basename>adaptor.{cpp,h} where basename defaults to the basename of the xml file.
If <classname> is provided, then it will be used as the classname of the
adaptor itself.
macro QT4_GENERATE_DBUS_INTERFACE( header [interfacename] OPTIONS ...)
generate the xml interface file from the given header.
If the optional argument interfacename is omitted, the name of the
interface file is constructed from the basename of the header with
the suffix .xml appended.
Options may be given to qdbuscpp2xml, such as those found when executing "qdbuscpp2xml --help"
macro QT4_CREATE_TRANSLATION( qm_files directories ... sources ...
ts_files ... OPTIONS ...)
out: qm_files
in: directories sources ts_files
options: flags to pass to lupdate, such as -extensions to specify
extensions for a directory scan.
generates commands to create .ts (vie lupdate) and .qm
(via lrelease) - files from directories and/or sources. The ts files are
created and/or updated in the source tree (unless given with full paths).
The qm files are generated in the build tree.
Updating the translations can be done by adding the qm_files
to the source list of your library/executable, so they are
always updated, or by adding a custom target to control when
they get updated/generated.
macro QT4_ADD_TRANSLATION( qm_files ts_files ... )
out: qm_files
in: ts_files
generates commands to create .qm from .ts - files. The generated
filenames can be found in qm_files. The ts_files
must exists and are not updated in any way.

Locate QuickTime This module defines QUICKTIME_LIBRARY
QUICKTIME_FOUND, if false, do not try to link to gdal
QUICKTIME_INCLUDE_DIR, where to find the headers
$QUICKTIME_DIR is an environment variable that would correspond to the
./configure --prefix=$QUICKTIME_DIR
Created by Eric Wing.
FindRTI
Try to find M&S HLA RTI libraries
This module finds if any HLA RTI is installed and locates the standard
RTI include files and libraries.
RTI is a simulation infrastructure standardized by IEEE and SISO. It
has a well defined C++ API that assures that simulation applications
are independent on a particular RTI implementation.
http://en.wikipedia.org/wiki/Run-Time_Infrastructure_(simulation)
This code sets the following variables:
RTI_INCLUDE_DIR = the directory where RTI includes file are found
RTI_LIBRARIES = The libraries to link against to use RTI
RTI_DEFINITIONS = -DRTI_USES_STD_FSTREAM
RTI_FOUND = Set to FALSE if any HLA RTI was not found
Report problems to <certi-devel@nongnu.org>
FindRuby
Find Ruby
This module finds if Ruby is installed and determines where the
include files and libraries are. Ruby 1.8 and 1.9 are supported. The
minimum required version specified in the find_package() command is
honored. It also determines what the name of the library is. This
code sets the following variables:
RUBY_EXECUTABLE = full path to the ruby binary
RUBY_INCLUDE_DIRS = include dirs to be used when using the ruby library
RUBY_LIBRARY = full path to the ruby library
RUBY_VERSION = the version of ruby which was found, e.g. "1.8.7"
RUBY_FOUND = set to true if ruby ws found successfully
RUBY_INCLUDE_PATH = same as RUBY_INCLUDE_DIRS, only provided for compatibility reasons, don't use it
FindSDL
Locate SDL library This module defines SDL_LIBRARY, the name of the
library to link against SDL_FOUND, if false, do not try to link to SDL
SDL_INCLUDE_DIR, where to find SDL.h
This module responds to the the flag: SDL_BUILDING_LIBRARY If this is
defined, then no SDL_main will be linked in because only applications
need main(). Otherwise, it is assumed you are building an application
and this module will attempt to locate and set the the proper link
flags as part of the returned SDL_LIBRARY variable.
Don't forget to include SDLmain.h and SDLmain.m your project for the
OS X framework based version. (Other versions link to -lSDLmain which
this module will try to find on your behalf.) Also for OS X, this
module will automatically add the -framework Cocoa on your behalf.
Additional Note: If you see an empty SDL_LIBRARY_TEMP in your
configuration and no SDL_LIBRARY, it means CMake did not find your SDL
library (SDL.dll, libsdl.so, SDL.framework, etc). Set
SDL_LIBRARY_TEMP to point to your SDL library, and configure again.
Similarly, if you see an empty SDLMAIN_LIBRARY, you should set this
value as appropriate. These values are used to generate the final
SDL_LIBRARY variable, but when these values are unset, SDL_LIBRARY
does not get created.
$SDLDIR is an environment variable that would correspond to the
./configure --prefix=$SDLDIR used in building SDL. l.e.galup 9-20-02
Modified by Eric Wing. Added code to assist with automated building
by using environmental variables and providing a more
controlled/consistent search behavior. Added new modifications to
recognize OS X frameworks and additional Unix paths (FreeBSD, etc).
Also corrected the header search path to follow "proper" SDL
guidelines. Added a search for SDLmain which is needed by some
platforms. Added a search for threads which is needed by some
platforms. Added needed compile switches for MinGW.
On OSX, this will prefer the Framework version (if found) over others.
People will have to manually change the cache values of SDL_LIBRARY to
override this selection or set the CMake environment
CMAKE_INCLUDE_PATH to modify the search paths.
Note that the header path has changed from SDL/SDL.h to just SDL.h
This needed to change because "proper" SDL convention is #include
"SDL.h", not <SDL/SDL.h>. This is done for portability reasons
because not all systems place things in SDL/ (see FreeBSD).
FindSDL_image
Locate SDL_image library This module defines SDLIMAGE_LIBRARY, the
name of the library to link against SDLIMAGE_FOUND, if false, do not
try to link to SDL SDLIMAGE_INCLUDE_DIR, where to find SDL/SDL.h
$SDLDIR is an environment variable that would correspond to the

FindSDL_mixer
Locate SDL_mixer library This module defines SDLMIXER_LIBRARY, the
name of the library to link against SDLMIXER_FOUND, if false, do not
try to link to SDL SDLMIXER_INCLUDE_DIR, where to find SDL/SDL.h
$SDLDIR is an environment variable that would correspond to the

FindSDL_ttf
Locate SDL_ttf library This module defines SDLTTF_LIBRARY, the name of
the library to link against SDLTTF_FOUND, if false, do not try to link
to SDL SDLTTF_INCLUDE_DIR, where to find SDL/SDL.h
$SDLDIR is an environment variable that would correspond to the
./configure --prefix=$SDLDIR used in building SDL.
Created by Eric Wing. This was influenced by the FindSDL.cmake
module, but with modifications to recognize OS X frameworks and
additional Unix paths (FreeBSD, etc).
FindSWIG
Find SWIG
This module finds an installed SWIG. It sets the following variables:
SWIG_FOUND - set to true if SWIG is found
SWIG_DIR - the directory where swig is installed
SWIG_EXECUTABLE - the path to the swig executable
SWIG_VERSION - the version number of the swig executable
All informations are collected from the SWIG_EXECUTABLE so the version
to be found can be changed from the command line by means of setting
SWIG_EXECUTABLE
FindSelfPackers
Find upx
This module looks for some executable packers (i.e. softwares that
compress executables or shared libs into on-the-fly self-extracting
executables or shared libs. Examples:
UPX: http://wildsau.idv.uni-linz.ac.at/mfx/upx.html

FindSubversion
Extract information from a subversion working copy
The module defines the following variables:
Subversion_SVN_EXECUTABLE - path to svn command line client
Subversion_VERSION_SVN - version of svn command line client
Subversion_FOUND - true if the command line client was found
If the command line client executable is found the macro
Subversion_WC_INFO(<dir> <var-prefix>)
is defined to extract information of a subversion working copy at a
given location. The macro defines the following variables:
<var-prefix>_WC_URL - url of the repository (at <dir>)
<var-prefix>_WC_ROOT - root url of the repository
<var-prefix>_WC_REVISION - current revision
<var-prefix>_WC_LAST_CHANGED_AUTHOR - author of last commit
<var-prefix>_WC_LAST_CHANGED_DATE - date of last commit
<var-prefix>_WC_LAST_CHANGED_REV - revision of last commit
<var-prefix>_WC_LAST_CHANGED_LOG - last log of base revision
<var-prefix>_WC_INFO - output of command `svn info <dir>'
Example usage:
FIND_PACKAGE(Subversion)
IF(Subversion_FOUND)
Subversion_WC_INFO(${PROJECT_SOURCE_DIR} Project)
MESSAGE("Current revision is ${Project_WC_REVISION}")
Subversion_WC_LOG(${PROJECT_SOURCE_DIR} Project)
MESSAGE("Last changed log is ${Project_LAST_CHANGED_LOG}")
ENDIF(Subversion_FOUND)
FindTCL
TK_INTERNAL_PATH was removed.
This module finds if Tcl is installed and determines where the include
files and libraries are. It also determines what the name of the
library is. This code sets the following variables:
TCL_FOUND = Tcl was found
TK_FOUND = Tk was found
TCLTK_FOUND = Tcl and Tk were found
TCL_LIBRARY = path to Tcl library (tcl tcl80)
TCL_INCLUDE_PATH = path to where tcl.h can be found
TCL_TCLSH = path to tclsh binary (tcl tcl80)
TK_LIBRARY = path to Tk library (tk tk80 etc)
TK_INCLUDE_PATH = path to where tk.h can be found
TK_WISH = full path to the wish executable
In an effort to remove some clutter and clear up some issues for
people who are not necessarily Tcl/Tk gurus/developpers, some
variables were moved or removed. Changes compared to CMake 2.4 are:
=> they were only useful for people writing Tcl/Tk extensions.
=> these libs are not packaged by default with Tcl/Tk distributions.
Even when Tcl/Tk is built from source, several flavors of debug libs
are created and there is no real reason to pick a single one
specifically (say, amongst tcl84g, tcl84gs, or tcl84sgx).
Let's leave that choice to the user by allowing him to assign
TCL_LIBRARY to any Tcl library, debug or not.
=> this ended up being only a Win32 variable, and there is a lot of
confusion regarding the location of this file in an installed Tcl/Tk
tree anyway (see 8.5 for example). If you need the internal path at
this point it is safer you ask directly where the *source* tree is
and dig from there.
FindTIFF
Find TIFF library
Find the native TIFF includes and library This module defines
TIFF_INCLUDE_DIR, where to find tiff.h, etc.
TIFF_LIBRARIES, libraries to link against to use TIFF.
TIFF_FOUND, If false, do not try to use TIFF.
also defined, but not for general use are
TIFF_LIBRARY, where to find the TIFF library.
FindTclStub
TCL_STUB_LIBRARY_DEBUG and TK_STUB_LIBRARY_DEBUG were removed.
This module finds Tcl stub libraries. It first finds Tcl include
files and libraries by calling FindTCL.cmake. How to Use the Tcl
Stubs Library:
http://tcl.activestate.com/doc/howto/stubs.html
Using Stub Libraries:
http://safari.oreilly.com/0130385603/ch48lev1sec3
This code sets the following variables:
TCL_STUB_LIBRARY = path to Tcl stub library
TK_STUB_LIBRARY = path to Tk stub library
TTK_STUB_LIBRARY = path to ttk stub library
In an effort to remove some clutter and clear up some issues for
people who are not necessarily Tcl/Tk gurus/developpers, some
variables were moved or removed. Changes compared to CMake 2.4 are:
=> these libs are not packaged by default with Tcl/Tk distributions.
Even when Tcl/Tk is built from source, several flavors of debug libs
are created and there is no real reason to pick a single one
specifically (say, amongst tclstub84g, tclstub84gs, or tclstub84sgx).
Let's leave that choice to the user by allowing him to assign
TCL_STUB_LIBRARY to any Tcl library, debug or not.
FindTclsh
Find tclsh
This module finds if TCL is installed and determines where the include
files and libraries are. It also determines what the name of the
library is. This code sets the following variables:
TCLSH_FOUND = TRUE if tclsh has been found
TCL_TCLSH = the path to the tclsh executable
In cygwin, look for the cygwin version first. Don't look for it later
to avoid finding the cygwin version on a Win32 build.
FindThreads
This module determines the thread library of the system.
The following variables are set
CMAKE_THREAD_LIBS_INIT - the thread library
CMAKE_USE_SPROC_INIT - are we using sproc?
CMAKE_USE_WIN32_THREADS_INIT - using WIN32 threads?
CMAKE_USE_PTHREADS_INIT - are we using pthreads
CMAKE_HP_PTHREADS_INIT - are we using hp pthreads
FindUnixCommands
Find unix commands from cygwin
This module looks for some usual Unix commands.
FindVTK
Find a VTK installation or build tree.
The following variables are set if VTK is found. If VTK is not found,
VTK_FOUND is set to false.
VTK_FOUND - Set to true when VTK is found.
VTK_USE_FILE - CMake file to use VTK.
VTK_MAJOR_VERSION - The VTK major version number.
VTK_MINOR_VERSION - The VTK minor version number
(odd non-release).
VTK_BUILD_VERSION - The VTK patch level
(meaningless for odd minor).
VTK_INCLUDE_DIRS - Include directories for VTK
VTK_LIBRARY_DIRS - Link directories for VTK libraries

The following cache entries must be set by the user to locate VTK:
VTK_DIR - The directory containing VTKConfig.cmake.
This is either the root of the build tree,
or the lib/vtk directory. This is the
only cache entry.
The following variables are set for backward compatibility and should
not be used in new code:
USE_VTK_FILE - The full path to the UseVTK.cmake file.
This is provided for backward
compatibility. Use VTK_USE_FILE
instead.

Findosg
NOTE: It is highly recommended that you use the new
FindOpenSceneGraph.cmake introduced in CMake 2.6.3 and not use this
Find module directly.
This is part of the Findosg* suite used to find OpenSceneGraph
components. Each component is separate and you must opt in to each
module. You must also opt into OpenGL and OpenThreads (and Producer
if needed) as these modules won't do it for you. This is to allow you
control over your own system piece by piece in case you need to opt
out of certain components or change the Find behavior for a particular
module (perhaps because the default FindOpenGL.cmake module doesn't
work with your system as an example). If you want to use a more
convenient module that includes everything, use the
FindOpenSceneGraph.cmake instead of the Findosg*.cmake modules.

Findosg_functions
This CMake file contains two macros to assist with searching for OSG
libraries and nodekits.
FindwxWidgets
Find a wxWidgets (a.k.a., wxWindows) installation.
This module finds if wxWidgets is installed and selects a default
configuration to use. wxWidgets is a modular library. To specify the
modules that you will use, you need to name them as components to the
package:
FIND_PACKAGE(wxWidgets COMPONENTS base core ...)
There are two search branches: a windows style and a unix style. For
windows, the following variables are searched for and set to defaults
in case of multiple choices. Change them if the defaults are not
desired (i.e., these are the only variables you should change to
select a configuration):
wxWidgets_ROOT_DIR - Base wxWidgets directory
(e.g., C:/wxWidgets-2.6.3).
wxWidgets_LIB_DIR - Path to wxWidgets libraries
(e.g., C:/wxWidgets-2.6.3/lib/vc_lib).
wxWidgets_CONFIGURATION - Configuration to use
(e.g., msw, mswd, mswu, mswunivud, etc.)
For unix style it uses the wx-config utility. You can select between
debug/release, unicode/ansi, universal/non-universal, and
static/shared in the QtDialog or ccmake interfaces by turning ON/OFF
the following variables:
wxWidgets_USE_DEBUG
wxWidgets_USE_UNICODE
wxWidgets_USE_UNIVERSAL
wxWidgets_USE_STATIC
The following are set after the configuration is done for both windows
and unix style:
wxWidgets_FOUND - Set to TRUE if wxWidgets was found.
wxWidgets_INCLUDE_DIRS - Include directories for WIN32
i.e., where to find "wx/wx.h" and
"wx/setup.h"; possibly empty for unices.
wxWidgets_LIBRARIES - Path to the wxWidgets libraries.
wxWidgets_LIBRARY_DIRS - compile time link dirs, useful for
rpath on UNIX. Typically an empty string
in WIN32 environment.
wxWidgets_DEFINITIONS - Contains defines required to compile/link
against WX, e.g. WXUSINGDLL
wxWidgets_DEFINITIONS_DEBUG- Contains defines required to compile/link
against WX debug builds, e.g. __WXDEBUG__
wxWidgets_CXX_FLAGS - Include dirs and compiler flags for
unices, empty on WIN32. Essentially
"`wx-config --cxxflags`".
wxWidgets_USE_FILE - Convenience include file.
Sample usage:
FIND_PACKAGE(wxWidgets COMPONENTS base core gl net)
IF(wxWidgets_FOUND)
INCLUDE(${wxWidgets_USE_FILE})
# and for each of your dependant executable/library targets:
TARGET_LINK_LIBRARIES(<YourTarget> ${wxWidgets_LIBRARIES})
ENDIF(wxWidgets_FOUND)
If wxWidgets is required (i.e., not an optional part):
FIND_PACKAGE(wxWidgets REQUIRED base core gl net)
INCLUDE(${wxWidgets_USE_FILE})
# and for each of your dependant executable/library targets:
TARGET_LINK_LIBRARIES(<YourTarget> ${wxWidgets_LIBRARIES})
FindwxWindows
Find wxWindows (wxWidgets) installation
This module finds if wxWindows/wxWidgets is installed and determines
where the include files and libraries are. It also determines what
the name of the library is. Please note this file is DEPRECATED and
replaced by FindwxWidgets.cmake. This code sets the following
variables:
WXWINDOWS_FOUND = system has WxWindows
WXWINDOWS_LIBRARIES = path to the wxWindows libraries
on Unix/Linux with additional
linker flags from
"wx-config --libs"
CMAKE_WXWINDOWS_CXX_FLAGS = Compiler flags for wxWindows,
essentially "`wx-config --cxxflags`"
on Linux
WXWINDOWS_INCLUDE_DIR = where to find "wx/wx.h" and "wx/setup.h"
WXWINDOWS_LINK_DIRECTORIES = link directories, useful for rpath on
Unix
WXWINDOWS_DEFINITIONS = extra defines
OPTIONS If you need OpenGL support please
SET(WXWINDOWS_USE_GL 1)
in your CMakeLists.txt *before* you include this file.
HAVE_ISYSTEM - true required to replace -I by -isystem on g++
For convenience include Use_wxWindows.cmake in your project's
CMakeLists.txt using INCLUDE(Use_wxWindows).
USAGE
SET(WXWINDOWS_USE_GL 1)
FIND_PACKAGE(wxWindows)
NOTES wxWidgets 2.6.x is supported for monolithic builds e.g.
compiled in wx/build/msw dir as:
nmake -f makefile.vc BUILD=debug SHARED=0 USE_OPENGL=1 MONOLITHIC=1
DEPRECATED
CMAKE_WX_CAN_COMPILE
WXWINDOWS_LIBRARY

FortranCInterface
Fortran/C Interface Detection
This module automatically detects the API by which C and Fortran
languages interact. Variables indicate if the mangling is found:
FortranCInterface_GLOBAL_FOUND = Global subroutines and functions
FortranCInterface_MODULE_FOUND = Module subroutines and functions
(declared by "MODULE PROCEDURE")
A function is provided to generate a C header file containing macros
to mangle symbol names:
FortranCInterface_HEADER(<file>
[MACRO_NAMESPACE <macro-ns>]
[SYMBOL_NAMESPACE <ns>]
[SYMBOLS [<module>:]<function> ...])
It generates in <file> definitions of the following macros:
#define FortranCInterface_GLOBAL (name,NAME) ...
#define FortranCInterface_GLOBAL_(name,NAME) ...
#define FortranCInterface_MODULE (mod,name, MOD,NAME) ...
#define FortranCInterface_MODULE_(mod,name, MOD,NAME) ...
These macros mangle four categories of Fortran symbols, respectively:
- Global symbols without '_': call mysub()
- Global symbols with '_' : call my_sub()
- Module symbols without '_': use mymod; call mysub()
- Module symbols with '_' : use mymod; call my_sub()
If mangling for a category is not known, its macro is left undefined.
All macros require raw names in both lower case and upper case. The
MACRO_NAMESPACE option replaces the default "FortranCInterface_"
prefix with a given namespace "<macro-ns>".
The SYMBOLS option lists symbols to mangle automatically with C
preprocessor definitions:
<function> ==> #define <ns><function> ...
<module>:<function> ==> #define <ns><module>_<function> ...
If the mangling for some symbol is not known then no preprocessor
definition is created, and a warning is displayed. The
SYMBOL_NAMESPACE option prefixes all preprocessor definitions
generated by the SYMBOLS option with a given namespace "<ns>".
Example usage:
include(FortranCInterface)
FortranCInterface_HEADER(FC.h MACRO_NAMESPACE "FC_")
This creates a "FC.h" header that defines mangling macros FC_GLOBAL(),
FC_GLOBAL_(), FC_MODULE(), and FC_MODULE_().
Example usage:
include(FortranCInterface)
FortranCInterface_HEADER(FCMangle.h
MACRO_NAMESPACE "FC_"
SYMBOL_NAMESPACE "FC_"
SYMBOLS mysub mymod:my_sub)
This creates a "FC.h" header that defines the same FC_*() mangling
macros as the previous example plus preprocessor symbols FC_mysub and
FC_mymod_my_sub.
Another function is provided to verify that the Fortran and C/C++
compilers work together:
FortranCInterface_VERIFY([CXX] [QUIET])
It tests whether a simple test executable using Fortran and C (and C++
when the CXX option is given) compiles and links successfully. The
result is stored in the cache entry FortranCInterface_VERIFIED_C (or
FortranCInterface_VERIFIED_CXX if CXX is given) as a boolean. If the
check fails and QUIET is not given the function terminates with a
FATAL_ERROR message describing the problem. The purpose of this check
is to stop a build early for incompatible compiler combinations.
FortranCInterface is aware of possible GLOBAL and MODULE manglings for
many Fortran compilers, but it also provides an interface to specify
new possible manglings. Set the variables
FortranCInterface_GLOBAL_SYMBOLS
FortranCInterface_MODULE_SYMBOLS
before including FortranCInterface to specify manglings of the symbols
"MySub", "My_Sub", "MyModule:MySub", and "My_Module:My_Sub". For
example, the code:
set(FortranCInterface_GLOBAL_SYMBOLS mysub_ my_sub__ MYSUB_)
# ^^^^^ ^^^^^^ ^^^^^
set(FortranCInterface_MODULE_SYMBOLS
__mymodule_MOD_mysub __my_module_MOD_my_sub)
# ^^^^^^^^ ^^^^^ ^^^^^^^^^ ^^^^^^
include(FortranCInterface)
tells FortranCInterface to try given GLOBAL and MODULE manglings.
(The carets point at raw symbol names for clarity in this example but
are not needed.)
GetPrerequisites
GetPrerequisites.cmake
This script provides functions to list the .dll, .dylib or .so files
that an executable or shared library file depends on. (Its
prerequisites.)
It uses various tools to obtain the list of required shared library
files:
dumpbin (Windows)
ldd (Linux/Unix)
otool (Mac OSX)
The following functions are provided by this script:
gp_append_unique
is_file_executable
gp_item_default_embedded_path
(projects can override with gp_item_default_embedded_path_override)
gp_resolve_item
(projects can override with gp_resolve_item_override)
gp_resolved_file_type
gp_file_type
get_prerequisites
list_prerequisites
list_prerequisites_by_glob
Requires CMake 2.6 or greater because it uses function, break, return
and PARENT_SCOPE.
InstallRequiredSystemLibraries
By including this file, all files in the
CMAKE_INSTALL_DEBUG_LIBRARIES, will be installed with INSTALL_PROGRAMS
into /bin for WIN32 and /lib for non-win32. If
CMAKE_SKIP_INSTALL_RULES is set to TRUE before including this file,
then the INSTALL command is not called. The use can use the variable
CMAKE_INSTALL_SYSTEM_RUNTIME_LIBS to use a custom install command and
install them into any directory they want. If it is the MSVC
compiler, then the microsoft run time libraries will be found add
automatically added to the CMAKE_INSTALL_DEBUG_LIBRARIES, and
installed. If CMAKE_INSTALL_DEBUG_LIBRARIES is set and it is the MSVC
compiler, then the debug libraries are installed when available. If
CMAKE_INSTALL_MFC_LIBRARIES is set then the MFC run time libraries are
installed as well as the CRT run time libraries.
MacroAddFileDependencies
MACRO_ADD_FILE_DEPENDENCIES(<_file> depend_files...)
Using the macro MACRO_ADD_FILE_DEPENDENCIES() is discouraged. There
are usually better ways to specifiy the correct dependencies.
MACRO_ADD_FILE_DEPENDENCIES(<_file> depend_files...) is just a
convenience wrapper around the OBJECT_DEPENDS source file property.
You can just use SET_PROPERTY(SOURCE <file> APPEND PROPERTY
OBJECT_DEPENDS depend_files) instead.
SelectLibraryConfigurations
select_library_configurations( basename )
This macro takes a library base name as an argument, and will choose
good values for basename_LIBRARY, basename_LIBRARIES,
basename_LIBRARY_DEBUG, and basename_LIBRARY_RELEASE depending on what
has been found and set. If only basename_LIBRARY_RELEASE is defined,
basename_LIBRARY, basename_LIBRARY_DEBUG, and basename_LIBRARY_RELEASE
will be set to the release value. If only basename_LIBRARY_DEBUG is
defined, then basename_LIBRARY, basename_LIBRARY_DEBUG and
basename_LIBRARY_RELEASE will take the debug value.
If the generator supports configuration types, then basename_LIBRARY
and basename_LIBRARIES will be set with debug and optimized flags
specifying the library to be used for the given configuration. If no
build type has been set or the generator in use does not support
configuration types, then basename_LIBRARY and basename_LIBRARIES will
take only the release values.
SquishTestScript
This script launches a GUI test using Squish. You should not call the
script directly; instead, you should access it via the SQUISH_ADD_TEST
macro that is defined in FindSquish.cmake.
This script starts the Squish server, launches the test on the client,
and finally stops the squish server. If any of these steps fail
(including if the tests do not pass) then a fatal error is raised.
TestBigEndian
Define macro to determine endian type
Check if the system is big endian or little endian
TEST_BIG_ENDIAN(VARIABLE)
VARIABLE - variable to store the result to
TestCXXAcceptsFlag
Test CXX compiler for a flag
Check if the CXX compiler accepts a flag

UseEcos
This module defines variables and macros required to build eCos
application.
This file contains the following macros:
ECOS_ADD_INCLUDE_DIRECTORIES() - add the eCos include dirs
ECOS_ADD_EXECUTABLE(name source1 ... sourceN ) - create an eCos
executable ECOS_ADJUST_DIRECTORY(VAR source1 ... sourceN ) - adjusts
the path of the source files and puts the result into VAR
Macros for selecting the toolchain: ECOS_USE_ARM_ELF_TOOLS() - enable
the ARM ELF toolchain for the directory where it is called
ECOS_USE_I386_ELF_TOOLS() - enable the i386 ELF toolchain for the
directory where it is called ECOS_USE_PPC_EABI_TOOLS() - enable the
PowerPC toolchain for the directory where it is called
It contains the following variables: ECOS_DEFINITIONS
ECOSCONFIG_EXECUTABLE ECOS_CONFIG_FILE - defaults to ecos.ecc, if your
eCos configuration file has a different name, adjust this variable for
internal use only:
ECOS_ADD_TARGET_LIB
UsePkgConfig
obsolete pkg-config module for CMake
Defines the following macros:
PKGCONFIG(package includedir libdir linkflags cflags)
Calling PKGCONFIG will fill the desired information into the 4 given
arguments, e.g. PKGCONFIG(libart-2.0 LIBART_INCLUDE_DIR
LIBART_LINK_DIR LIBART_LINK_FLAGS LIBART_CFLAGS) if pkg-config was NOT
found or the specified software package doesn't exist, the variable
will be empty when the function returns, otherwise they will contain
the respective information
UseQt4
Use Module for QT4
Sets up C and C++ to use Qt 4. It is assumed that FindQt.cmake has
already been loaded. See FindQt.cmake for information on how to load
Qt 4 into your CMake project.
UseSWIG
SWIG module for CMake
Defines the following macros:
SWIG_ADD_MODULE(name language [ files ])
- Define swig module with given name and specified language
SWIG_LINK_LIBRARIES(name [ libraries ])
- Link libraries to swig module
All other macros are for internal use only. To get the actual name of
the swig module, use: ${SWIG_MODULE_${name}_REAL_NAME}. Set Source
files properties such as CPLUSPLUS and SWIG_FLAGS to specify special
behavior of SWIG. Also global CMAKE_SWIG_FLAGS can be used to add
special flags to all swig calls. Another special variable is
CMAKE_SWIG_OUTDIR, it allows one to specify where to write all the
swig generated module (swig -outdir option) The name-specific variable
SWIG_MODULE_<name>_EXTRA_DEPS may be used to specify extra
dependencies for the generated modules. If the source file generated
by swig need some special flag you can use
SET_SOURCE_FILES_PROPERTIES( ${swig_generated_file_fullname}
PROPERTIES COMPILE_FLAGS "-bla")

Variables
------------------------------------------------------------------------------
Variables That Change Behavior
BUILD_SHARED_LIBS
Global flag to cause add_library to create shared libraries if on.
If present and true, this will cause all libraries to be built shared
unless the library was explicitly added as a static library. This
variable is often added to projects as an OPTION so that each user of
a project can decide if they want to build the project using shared or
static libraries.
CMAKE_BACKWARDS_COMPATIBILITY
Version of cmake required to build project
From the point of view of backwards compatibility, this specifies what
version of CMake should be supported. By default this value is the
version number of CMake that you are running. You can set this to an
older version of CMake to support deprecated commands of CMake in
projects that were written to use older versions of CMake. This can
be set by the user or set at the beginning of a CMakeLists file.
CMAKE_BUILD_TYPE
Specifies the build type for make based generators.
This specifies what build type will be built in this tree. Possible
values are empty, Debug, Release, RelWithDebInfo and MinSizeRel. This
variable is only supported for make based generators. If this
variable is supported, then CMake will also provide initial values for
the variables with the name
CMAKE_C_FLAGS_[Debug|Release|RelWithDebInfo|MinSizeRel]. For example,
if CMAKE_BUILD_TYPE is Debug, then CMAKE_C_FLAGS_DEBUG will be added
to the CMAKE_C_FLAGS.
CMAKE_COLOR_MAKEFILE
Enables color output when using the Makefile generator.
When enabled, the generated Makefiles will produce colored output.
Default is ON.
CMAKE_CONFIGURATION_TYPES
Specifies the available build types.
This specifies what build types will be available such as Debug,
Release, RelWithDebInfo etc. This has reasonable defaults on most
platforms. But can be extended to provide other build types. See
also CMAKE_BUILD_TYPE.
CMAKE_FIND_LIBRARY_PREFIXES
Prefixes to prepend when looking for libraries.
This specifies what prefixes to add to library names when the
find_library command looks for libraries. On UNIX systems this is
typically lib, meaning that when trying to find the foo library it
will look for libfoo.
CMAKE_FIND_LIBRARY_SUFFIXES
Suffixes to append when looking for libraries.
This specifies what suffixes to add to library names when the
find_library command looks for libraries. On Windows systems this is
typically .lib and .dll, meaning that when trying to find the foo
library it will look for foo.dll etc.
CMAKE_INCLUDE_PATH
Path used for searching by FIND_FILE() and FIND_PATH().
Specifies a path which will be used both by FIND_FILE() and
FIND_PATH(). Both commands will check each of the contained
directories for the existence of the file which is currently searched.
By default it is empty, it is intended to be set by the project. See
also CMAKE_SYSTEM_INCLUDE_PATH, CMAKE_PREFIX_PATH.
CMAKE_INSTALL_PREFIX
Install directory used by install.
If "make install" is invoked or INSTALL is built, this directory is
pre-pended onto all install directories. This variable defaults to
/usr/local on UNIX and c:/Program Files on Windows.
CMAKE_LIBRARY_PATH
Path used for searching by FIND_LIBRARY().
Specifies a path which will be used by FIND_LIBRARY(). FIND_LIBRARY()
will check each of the contained directories for the existence of the
library which is currently searched. By default it is empty, it is
intended to be set by the project. See also
CMAKE_SYSTEM_LIBRARY_PATH, CMAKE_PREFIX_PATH.
CMAKE_MFC_FLAG
Tell cmake to use MFC for an executable or dll.
This can be set in a CMakeLists.txt file and will enable MFC in the
application. It should be set to 1 for static the static MFC library,
and 2 for the shared MFC library. This is used in visual studio 6 and
7 project files. The CMakeSetup dialog used MFC and the
CMakeLists.txt looks like this:
add_definitions(-D_AFXDLL)
set(CMAKE_MFC_FLAG 2)
add_executable(CMakeSetup WIN32 ${SRCS})
CMAKE_MODULE_PATH
Path to look for cmake modules to load.
Specifies a path to override the default search path for CMake
modules. For example include commands will look in this path first
for modules to include.
CMAKE_NOT_USING_CONFIG_FLAGS
Skip _BUILD_TYPE flags if true.
This is an internal flag used by the generators in CMake to tell CMake
to skip the _BUILD_TYPE flags.
CMAKE_PREFIX_PATH
Path used for searching by FIND_XXX(), with appropriate suffixes
added.
Specifies a path which will be used by the FIND_XXX() commands. It
contains the "base" directories, the FIND_XXX() commands append
appropriate subdirectories to the base directories. So FIND_PROGRAM()
adds /bin to each of the directories in the path, FIND_LIBRARY()
appends /lib to each of the directories, and FIND_PATH() and
FIND_FILE() append /include . By default it is empty, it is intended
to be set by the project. See also CMAKE_SYSTEM_PREFIX_PATH,
CMAKE_INCLUDE_PATH, CMAKE_LIBRARY_PATH, CMAKE_PROGRAM_PATH.
CMAKE_PROGRAM_PATH
Path used for searching by FIND_PROGRAM().
Specifies a path which will be used by FIND_PROGRAM(). FIND_PROGRAM()
will check each of the contained directories for the existence of the
program which is currently searched. By default it is empty, it is
intended to be set by the project. See also
CMAKE_SYSTEM_PROGRAM_PATH, CMAKE_PREFIX_PATH.
CMAKE_SKIP_INSTALL_ALL_DEPENDENCY
Don't make the install target depend on the all target.
By default, the "install" target depends on the "all" target. This
has the effect, that when "make install" is invoked or INSTALL is
built, first the "all" target is built, then the installation starts.
If CMAKE_SKIP_INSTALL_ALL_DEPENDENCY is set to TRUE, this dependency
is not created, so the installation process will start immediately,
independent from whether the project has been completely built or not.
CMAKE_SYSTEM_INCLUDE_PATH
Path used for searching by FIND_FILE() and FIND_PATH().
Specifies a path which will be used both by FIND_FILE() and
FIND_PATH(). Both commands will check each of the contained
directories for the existence of the file which is currently searched.
By default it contains the standard directories for the current
system. It is NOT intended to be modified by the project, use
CMAKE_INCLUDE_PATH for this. See also CMAKE_SYSTEM_PREFIX_PATH.
CMAKE_SYSTEM_LIBRARY_PATH
Path used for searching by FIND_LIBRARY().
Specifies a path which will be used by FIND_LIBRARY(). FIND_LIBRARY()
will check each of the contained directories for the existence of the
library which is currently searched. By default it contains the
standard directories for the current system. It is NOT intended to be
modified by the project, use CMAKE_SYSTEM_LIBRARY_PATH for this. See
also CMAKE_SYSTEM_PREFIX_PATH.
CMAKE_SYSTEM_PREFIX_PATH
Path used for searching by FIND_XXX(), with appropriate suffixes
added.
Specifies a path which will be used by the FIND_XXX() commands. It
contains the "base" directories, the FIND_XXX() commands append
appropriate subdirectories to the base directories. So FIND_PROGRAM()
adds /bin to each of the directories in the path, FIND_LIBRARY()
appends /lib to each of the directories, and FIND_PATH() and
FIND_FILE() append /include . By default this contains the standard
directories for the current system. It is NOT intended to be modified
by the project, use CMAKE_PREFIX_PATH for this. See also
CMAKE_SYSTEM_INCLUDE_PATH, CMAKE_SYSTEM_LIBRARY_PATH,
CMAKE_SYSTEM_PROGRAM_PATH.
CMAKE_SYSTEM_PROGRAM_PATH
Path used for searching by FIND_PROGRAM().
Specifies a path which will be used by FIND_PROGRAM(). FIND_PROGRAM()
will check each of the contained directories for the existence of the
program which is currently searched. By default it contains the
standard directories for the current system. It is NOT intended to be
modified by the project, use CMAKE_PROGRAM_PATH for this. See also
CMAKE_SYSTEM_PREFIX_PATH.
CMAKE_USER_MAKE_RULES_OVERRIDE
Specify a file that can change the build rule variables.
If this variable is set, it should to point to a CMakeLists.txt file
that will be read in by CMake after all the system settings have been
set, but before they have been used. This would allow you to override
any variables that need to be changed for some special project.
------------------------------------------------------------------------------

The same as CMAKE_SYSTEM but for the host system instead of the target
system when cross compiling.
CMAKE_HOST_SYSTEM_NAME
Name of the OS CMake is running on.
The same as CMAKE_SYSTEM_NAME but for the host system instead of the
target system when cross compiling.
CMAKE_HOST_SYSTEM_PROCESSOR
The name of the CPU CMake is running on.
The same as CMAKE_SYSTEM_PROCESSOR but for the host system instead of
the target system when cross compiling.
CMAKE_HOST_SYSTEM_VERSION

CYGWIN).
CMAKE_HOST_WIN32
True on windows systems, including win64.
Set to true when the host system is Windows and on cygwin.
CMAKE_OBJECT_PATH_MAX
Maximum object file full-path length allowed by native build tools.
CMake computes for every source file an object file name that is
unique to the source file and deterministic with respect to the full
path to the source file. This allows multiple source files in a
target to share the same name if they lie in different directories
without rebuilding when one is added or removed. However, it can
produce long full paths in a few cases, so CMake shortens the path
using a hashing scheme when the full path to an object file exceeds a
limit. CMake has a built-in limit for each platform that is
sufficient for common tools, but some native tools may have a lower
limit. This variable may be set to specify the limit explicitly. The
value must be an integer no less than 128.
CMAKE_SYSTEM
Name of system cmake is compiling for.
This variable is the composite of CMAKE_SYSTEM_NAME and
CMAKE_SYSTEM_VERSION, like this
${CMAKE_SYSTEM_NAME}-${CMAKE_SYSTEM_VERSION}. If CMAKE_SYSTEM_VERSION
is not set, then CMAKE_SYSTEM is the same as CMAKE_SYSTEM_NAME.
CMAKE_SYSTEM_NAME
Name of the OS CMake is building for.
This is the name of the operating system on which CMake is targeting.
On systems that have the uname command, this variable is set to the
output of uname -s. Linux, Windows, and Darwin for Mac OSX are the
values found on the big three operating systems.
CMAKE_SYSTEM_PROCESSOR

On systems that support uname, this variable is set to the output of
uname -p, on windows it is set to the value of the environment
variable PROCESSOR_ARCHITECTURE
CMAKE_SYSTEM_VERSION
OS version CMake is building for.
A numeric version string for the system, on systems that support
uname, this variable is set to the output of uname -r. On other
systems this is set to major-minor version numbers.

Set to true when using CYGWIN.
MSVC
True when using Microsoft Visual C
Set to true when the compiler is some version of Microsoft Visual C.
MSVC80

Version of Xcode (Xcode generator only).
Under the Xcode generator, this is the version of Xcode as specified
in "Xcode.app/Contents/version.plist" (such as "3.1.2").
------------------------------------------------------------------------------
Variables for Languages
CMAKE_<LANG>_ARCHIVE_APPEND
Rule variable to append to a static archive.
This is a rule variable that tells CMake how to append to a static
archive. It is used in place of CMAKE_<LANG>_CREATE_STATIC_LIBRARY on
some platforms in order to support large object counts. See also
CMAKE_<LANG>_ARCHIVE_CREATE and CMAKE_<LANG>_ARCHIVE_FINISH.
CMAKE_<LANG>_ARCHIVE_CREATE
Rule variable to create a new static archive.
This is a rule variable that tells CMake how to create a static
archive. It is used in place of CMAKE_<LANG>_CREATE_STATIC_LIBRARY on
some platforms in order to support large object counts. See also
CMAKE_<LANG>_ARCHIVE_APPEND and CMAKE_<LANG>_ARCHIVE_FINISH.
CMAKE_<LANG>_ARCHIVE_FINISH
Rule variable to finish an existing static archive.
This is a rule variable that tells CMake how to finish a static
archive. It is used in place of CMAKE_<LANG>_CREATE_STATIC_LIBRARY on
some platforms in order to support large object counts. See also
CMAKE_<LANG>_ARCHIVE_CREATE and CMAKE_<LANG>_ARCHIVE_APPEND.
CMAKE_<LANG>_COMPILER
The full path to the compiler for LANG.
This is the command that will be used as the <LANG> compiler. Once
set, you can not change this variable.
CMAKE_<LANG>_COMPILER_ABI
An internal variable subject to change.
This is used in determining the compiler ABI and is subject to change.
CMAKE_<LANG>_COMPILER_ID
An internal variable subject to change.
This is used in determining the compiler and is subject to change.
CMAKE_<LANG>_COMPILER_LOADED
Defined to true if the language is enabled.
When language <LANG> is enabled by project() or enable_language() this
variable is defined to 1.
CMAKE_<LANG>_COMPILE_OBJECT
Rule variable to compile a single object file.
This is a rule variable that tells CMake how to compile a single
object file for for the language <LANG>.
CMAKE_<LANG>_CREATE_SHARED_LIBRARY
Rule variable to create a shared library.
This is a rule variable that tells CMake how to create a shared
library for the language <LANG>.
CMAKE_<LANG>_CREATE_SHARED_MODULE
Rule variable to create a shared module.
This is a rule variable that tells CMake how to create a shared
library for the language <LANG>.
CMAKE_<LANG>_CREATE_STATIC_LIBRARY
Rule variable to create a static library.
This is a rule variable that tells CMake how to create a static
library for the language <LANG>.
CMAKE_<LANG>_FLAGS_DEBUG
Flags for Debug build type or configuration.
<LANG> flags used when CMAKE_BUILD_TYPE is Debug.
CMAKE_<LANG>_FLAGS_MINSIZEREL
Flags for MinSizeRel build type or configuration.
<LANG> flags used when CMAKE_BUILD_TYPE is MinSizeRel.Short for
minimum size release.
CMAKE_<LANG>_FLAGS_RELEASE
Flags for Release build type or configuration.
<LANG> flags used when CMAKE_BUILD_TYPE is Release
CMAKE_<LANG>_FLAGS_RELWITHDEBINFO
Flags for RelWithDebInfo type or configuration.
<LANG> flags used when CMAKE_BUILD_TYPE is RelWithDebInfo. Short for
Release With Debug Information.
CMAKE_<LANG>_IGNORE_EXTENSIONS
File extensions that should be ignored by the build.
This is a list of file extensions that may be part of a project for a
given language but are not compiled.
CMAKE_<LANG>_IMPLICIT_INCLUDE_DIRECTORIES
Directories implicitly searched by the compiler for header files.
CMake does not explicitly specify these directories on compiler
command lines for language <LANG>. This prevents system include
directories from being treated as user include directories on some
compilers.
CMAKE_<LANG>_IMPLICIT_LINK_DIRECTORIES
Implicit linker search path detected for language <LANG>.
Compilers typically pass directories containing language runtime
libraries and default library search paths when they invoke a linker.
These paths are implicit linker search directories for the compiler's
language. CMake automatically detects these directories for each
language and reports the results in this variable.
CMAKE_<LANG>_IMPLICIT_LINK_LIBRARIES
Implicit link libraries and flags detected for language <LANG>.
Compilers typically pass language runtime library names and other
flags when they invoke a linker. These flags are implicit link
options for the compiler's language. CMake automatically detects
these libraries and flags for each language and reports the results in
this variable.
CMAKE_<LANG>_LINKER_PREFERENCE
Preference value for linker language selection.
The "linker language" for executable, shared library, and module
targets is the language whose compiler will invoke the linker. The
LINKER_LANGUAGE target property sets the language explicitly.
Otherwise, the linker language is that whose linker preference value
is highest among languages compiled and linked into the target. See
also the CMAKE_<LANG>_LINKER_PREFERENCE_PROPAGATES variable.
CMAKE_<LANG>_LINKER_PREFERENCE_PROPAGATES
True if CMAKE_<LANG>_LINKER_PREFERENCE propagates across targets.
This is used when CMake selects a linker language for a target.
Languages compiled directly into the target are always considered. A
language compiled into static libraries linked by the target is
considered if this variable is true.
CMAKE_<LANG>_LINK_EXECUTABLE
Rule variable to link and executable.
Rule variable to link and executable for the given language.
CMAKE_<LANG>_OUTPUT_EXTENSION
Extension for the output of a compile for a single file.
This is the extension for an object file for the given <LANG>. For
example .obj for C on Windows.
CMAKE_<LANG>_PLATFORM_ID
An internal variable subject to change.
This is used in determining the platform and is subject to change.
CMAKE_<LANG>_SIZEOF_DATA_PTR
Size of pointer-to-data types for language <LANG>.
This holds the size (in bytes) of pointer-to-data types in the target
platform ABI. It is defined for languages C and CXX (C++).
CMAKE_<LANG>_SOURCE_FILE_EXTENSIONS
Extensions of source files for the given language.
This is the list of extensions for a given languages source files.
CMAKE_COMPILER_IS_GNU<LANG>
True if the compiler is GNU.
If the selected <LANG> compiler is the GNU compiler then this is TRUE,
if not it is FALSE.
CMAKE_INTERNAL_PLATFORM_ABI
An internal variable subject to change.
This is used in determining the compiler ABI and is subject to change.
CMAKE_USER_MAKE_RULES_OVERRIDE_<LANG>
Specify a file that can change the build rule variables.
If this variable is set, it should to point to a CMakeLists.txt file
that will be read in by CMake after all the system settings have been
set, but before they have been used. This would allow you to override
any variables that need to be changed for some language.
------------------------------------------------------------------------------
Variables that Control the Build
CMAKE_<CONFIG>_POSTFIX
Default filename postfix for libraries under configuration <CONFIG>.
When a non-executable target is created its <CONFIG>_POSTFIX target
property is initialized with the value of this variable if it is set.
CMAKE_ARCHIVE_OUTPUT_DIRECTORY
Where to put all the ARCHIVE targets when built.
This variable is used to initialize the ARCHIVE_OUTPUT_DIRECTORY
property on all the targets. See that target property for additional
information.
CMAKE_BUILD_WITH_INSTALL_RPATH
Use the install path for the RPATH
Normally CMake uses the build tree for the RPATH when building
executables etc on systems that use RPATH. When the software is
installed the executables etc are relinked by CMake to have the
install RPATH. If this variable is set to true then the software is
always built with the install path for the RPATH and does not need to
be relinked when installed.
CMAKE_DEBUG_POSTFIX
See variable CMAKE_<CONFIG>_POSTFIX.
This variable is a special case of the more-general
CMAKE_<CONFIG>_POSTFIX variable for the DEBUG configuration.
CMAKE_EXE_LINKER_FLAGS
Linker flags used to create executables.
Flags used by the linker when creating an executable.
CMAKE_EXE_LINKER_FLAGS_[CMAKE_BUILD_TYPE]
Flag used when linking an executable.
Same as CMAKE_C_FLAGS_* but used by the linker when creating
executables.
CMAKE_Fortran_MODULE_DIRECTORY
Fortran module output directory.
This variable is used to initialize the Fortran_MODULE_DIRECTORY
property on all the targets. See that target property for additional
information.
CMAKE_INCLUDE_CURRENT_DIR
Automatically add the current source- and build directories to the
include path.
If this variable is enabled, CMake automatically adds in each
directory ${CMAKE_CURRENT_SOURCE_DIR} and ${CMAKE_CURRENT_BINARY_DIR}
to the include path for this directory. These additional include
directories do not propagate down to subdirectories. This is useful
mainly for out-of-source builds, where files generated into the build
tree are included by files located in the source tree.
By default CMAKE_INCLUDE_CURRENT_DIR is OFF.
CMAKE_INSTALL_NAME_DIR
Mac OSX directory name for installed targets.
CMAKE_INSTALL_NAME_DIR is used to initialize the INSTALL_NAME_DIR
property on all targets. See that target property for more
information.
CMAKE_INSTALL_RPATH
The rpath to use for installed targets.
A semicolon-separated list specifying the rpath to use in installed
targets (for platforms that support it). This is used to initialize
the target property INSTALL_RPATH for all targets.
CMAKE_INSTALL_RPATH_USE_LINK_PATH
Add paths to linker search and installed rpath.
CMAKE_INSTALL_RPATH_USE_LINK_PATH is a boolean that if set to true
will append directories in the linker search path and outside the
project to the INSTALL_RPATH. This is used to initialize the target
property INSTALL_RPATH_USE_LINK_PATH for all targets.
CMAKE_LIBRARY_OUTPUT_DIRECTORY
Where to put all the LIBRARY targets when built.
This variable is used to initialize the LIBRARY_OUTPUT_DIRECTORY
property on all the targets. See that target property for additional
information.
CMAKE_LIBRARY_PATH_FLAG
The flag used to add a library search path to a compiler.
The flag used to specify a library directory to the compiler. On most
compilers this is "-L".
CMAKE_LINK_DEF_FILE_FLAG
Linker flag used to specify a .def file for dll creation.
The flag used to add a .def file when creating a dll on Windows, this
is only defined on Windows.
CMAKE_LINK_LIBRARY_FILE_FLAG
Flag used to link a library specified by a path to its file.
The flag used before a library file path is given to the linker. This
is needed only on very few platforms.
CMAKE_LINK_LIBRARY_FLAG
Flag used to link a library into an executable.
The flag used to specify a library to link to an executable. On most
compilers this is "-l".
CMAKE_NO_BUILTIN_CHRPATH
Do not use the builtin ELF editor to fix RPATHs on installation.
When an ELF binary needs to have a different RPATH after installation
than it does in the build tree, CMake uses a builtin editor to change
the RPATH in the installed copy. If this variable is set to true then
CMake will relink the binary before installation instead of using its
builtin editor.
CMAKE_RUNTIME_OUTPUT_DIRECTORY
Where to put all the RUNTIME targets when built.
This variable is used to initialize the RUNTIME_OUTPUT_DIRECTORY
property on all the targets. See that target property for additional
information.
CMAKE_SKIP_BUILD_RPATH
Do not include RPATHs in the build tree.
Normally CMake uses the build tree for the RPATH when building
executables etc on systems that use RPATH. When the software is
installed the executables etc are relinked by CMake to have the
install RPATH. If this variable is set to true then the software is
always built with no RPATH.
CMAKE_USE_RELATIVE_PATHS
Use relative paths (May not work!).
If this is set to TRUE, then the CMake will use relative paths between
the source and binary tree. This option does not work for more
complicated projects, and relative paths are used when possible. In
general, it is not possible to move CMake generated makefiles to a
different location regardless of the value of this variable.
EXECUTABLE_OUTPUT_PATH
Old executable location variable.
The target property RUNTIME_OUTPUT_DIRECTORY supercedes this variable
for a target if it is set. Executable targets are otherwise placed in
this directory.
LIBRARY_OUTPUT_PATH
Old library location variable.
The target properties ARCHIVE_OUTPUT_DIRECTORY,
LIBRARY_OUTPUT_DIRECTORY, and RUNTIME_OUTPUT_DIRECTORY supercede this
variable for a target if they are set. Library targets are otherwise
placed in this directory.

Variables that Provide Information
CMAKE_AR
Name of archiving tool for static libraries.
This specifies name of the program that creates archive or static
libraries.
CMAKE_BINARY_DIR
The path to the top level of the build tree.
This is the full path to the top level of the current CMake build
tree. For an in-source build, this would be the same as
CMAKE_SOURCE_DIR.
CMAKE_BUILD_TOOL
Tool used for the actual build process.
This variable is set to the program that will be needed to build the
output of CMake. If the generator selected was Visual Studio 6, the
CMAKE_MAKE_PROGRAM will be set to msdev, for Unix makefiles it will be
set to make or gmake, and for Visual Studio 7 it set to devenv. For
Nmake Makefiles the value is nmake. This can be useful for adding
special flags and commands based on the final build environment.
CMAKE_CACHEFILE_DIR
The directory with the CMakeCache.txt file.
This is the full path to the directory that has the CMakeCache.txt
file in it. This is the same as CMAKE_BINARY_DIR.
CMAKE_CACHE_MAJOR_VERSION
Major version of CMake used to create the CMakeCache.txt file
This is stores the major version of CMake used to write a CMake cache
file. It is only different when a different version of CMake is run
on a previously created cache file.
CMAKE_CACHE_MINOR_VERSION
Minor version of CMake used to create the CMakeCache.txt file
This is stores the minor version of CMake used to write a CMake cache
file. It is only different when a different version of CMake is run
on a previously created cache file.
CMAKE_CACHE_PATCH_VERSION
Patch version of CMake used to create the CMakeCache.txt file
This is stores the patch version of CMake used to write a CMake cache
file. It is only different when a different version of CMake is run
on a previously created cache file.
CMAKE_CFG_INTDIR
Build-time reference to per-configuration output subdirectory.
For native build systems supporting multiple configurations in the
build tree (such as Visual Studio and Xcode), the value is a reference
to a build-time variable specifying the name of the per-configuration
output subdirectory. On Makefile generators this evaluates to "."
because there is only one configuration in a build tree. Example
values:
$(IntDir) = Visual Studio 6
$(OutDir) = Visual Studio 7, 8, 9
$(Configuration) = Visual Studio 10
$(CONFIGURATION) = Xcode
. = Make-based tools
Since these values are evaluated by the native build system, this
variable is suitable only for use in command lines that will be
evaluated at build time. Example of intended usage:
add_executable(mytool mytool.c)
add_custom_command(
OUTPUT out.txt
COMMAND ${CMAKE_CURRENT_BINARY_DIR}/${CMAKE_CFG_INTDIR}/mytool
${CMAKE_CURRENT_SOURCE_DIR}/in.txt out.txt
DEPENDS mytool in.txt
)
add_custom_target(drive ALL DEPENDS out.txt)
Note that CMAKE_CFG_INTDIR is no longer necessary for this purpose but
has been left for compatibility with existing projects. Instead
add_custom_command() recognizes executable target names in its COMMAND
option, so "${CMAKE_CURRENT_BINARY_DIR}/${CMAKE_CFG_INTDIR}/mytool"
can be replaced by just "mytool".
This variable is read-only. Setting it is undefined behavior. In
multi-configuration build systems the value of this variable is passed
as the value of preprocessor symbol "CMAKE_INTDIR" to the compilation
of all source files.
CMAKE_COMMAND
The full path to the cmake executable.
This is the full path to the CMake executable cmake which is useful
from custom commands that want to use the cmake -E option for portable
system commands. (e.g. /usr/local/bin/cmake
CMAKE_CROSSCOMPILING
Is CMake currently cross compiling.
This variable will be set to true by CMake if CMake is cross
compiling. Specifically if the build platform is different from the
target platform.
CMAKE_CTEST_COMMAND
Full path to ctest command installed with cmake.
This is the full path to the CTest executable ctest which is useful
from custom commands that want to use the cmake -E option for portable
system commands.
CMAKE_CURRENT_BINARY_DIR
The path to the binary directory currently being processed.
This the full path to the build directory that is currently being
processed by cmake. Each directory added by add_subdirectory will
create a binary directory in the build tree, and as it is being
processed this variable will be set. For in-source builds this is the
current source directory being processed.
CMAKE_CURRENT_LIST_FILE
Full path to the listfile currently being processed.
As CMake processes the listfiles in your project this variable will
always be set to the one currently being processed. The value has
dynamic scope. When CMake starts processing commands in a source file
it sets this variable to the location of the file. When CMake
finishes processing commands from the file it restores the previous
value. Therefore the value of the variable inside a macro or function
is the file invoking the bottom-most entry on the call stack, not the
file containing the macro or function definition.
See also CMAKE_PARENT_LIST_FILE.
CMAKE_CURRENT_LIST_LINE
The line number of the current file being processed.
This is the line number of the file currently being processed by
cmake.

external shared library files during analysis of libraries linked by a
target.
CMAKE_GENERATOR

by a try compile. If a 64 bit size is found, then the library search
path is modified to look for 64 bit libraries first.
CMAKE_SKIP_RPATH
If true, do not add run time path information.
If this is set to TRUE, then the rpath information is not added to
compiled executables. The default is to add rpath information if the
platform supports it.This allows for easy running from the build tree.
CMAKE_SOURCE_DIR
