------------------------------------------------------------------------------
Introduction
cmake-variables - Reference of CMake variables.
------------------------------------------------------------------------------
Variables that Provide Information
variables defined by cmake, that give information about the project, and
cmake
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.
CMAKE_CURRENT_SOURCE_DIR
The path to the source directory currently being processed.
This the full path to the source directory that is currently being
processed by cmake.
CMAKE_DL_LIBS

-ldl on most UNIX machines.
CMAKE_EDIT_COMMAND
Full path to cmake-gui or ccmake.
This is the full path to the CMake executable that can graphically
edit the cache. For example, cmake-gui, ccmake, or cmake -i.
CMAKE_EXECUTABLE_SUFFIX

Windows.
CMAKE_EXECUTABLE_SUFFIX_<LANG> overrides this for language <LANG>.
CMAKE_EXTRA_SHARED_LIBRARY_SUFFIXES
Additional suffixes for shared libraries.
Extensions for shared libraries other than that specified by
CMAKE_SHARED_LIBRARY_SUFFIX, if any. CMake uses this to recognize
external shared library files during analysis of libraries linked by a
target.
CMAKE_GENERATOR
The generator used to build the project.
The name of the generator that is being used to generate the build
files. (e.g. "Unix Makefiles", "Visual Studio 6", etc.)

This specifies the minor version of the CMake executable being run.
CMAKE_PARENT_LIST_FILE
Full path to the parent listfile of the one currently being processed.

always be set to the listfile that included or somehow invoked the one
currently being processed. See also CMAKE_CURRENT_LIST_FILE.
CMAKE_PATCH_VERSION
The patch version of cmake (i.e. the 3 in X.X.3).
This specifies the patch version of the CMake executable being run.
CMAKE_PROJECT_NAME
The name of the current project.
This specifies name of the current project from the closest inherited
PROJECT command.
CMAKE_RANLIB

CMAKE_SIZEOF_VOID_P
Size of a void pointer.
This is set to the size of a pointer on the machine, and is determined
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
The path to the top level of the source tree.
This is the full path to the top level of the current CMake source
tree. For an in-source build, this would be the same as

A variable is created with the name used in the PROJECT command, and
is the binary directory for the project. This can be useful when
SUBDIR is used to connect several projects.
[Project name]_SOURCE_DIR
Top level source directory for the named project.
A variable is created with the name used in the PROJECT command, and
is the source directory for the project. This can be useful when
add_subdirectory is used to connect several projects.
------------------------------------------------------------------------------
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.
------------------------------------------------------------------------------
Variables That Describe the System
APPLE
True if running on Mac OSX.
Set to true on Mac OSX.
BORLAND
True of the borland compiler is being used.
This is set to true if the Borland compiler is being used.
CMAKE_CL_64
Using the 64 bit compiler from Microsoft
Set to true when using the 64 bit cl compiler from Microsoft.
CMAKE_COMPILER_2005
Using the Visual Studio 2005 compiler from Microsoft
Set to true when using the Visual Studio 2005 compiler from Microsoft.
CMAKE_HOST_APPLE
True for Apple OSXoperating systems.
Set to true when the host system is Apple OSX.
CMAKE_HOST_SYSTEM
Name of system cmake is being run on.
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
OS version CMake is running on.
The same as CMAKE_SYSTEM_VERSION but for the host system instead of
the target system when cross compiling.
CMAKE_HOST_UNIX
True for UNIX and UNIX like operating systems.
Set to true when the host system is UNIX or UNIX like (i.e. APPLE and
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
The name of the CPU CMake is building for.
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.
CYGWIN
True for cygwin.
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
True when using Microsoft Visual C 8.0
Set to true when the compiler is version 8.0 of Microsoft Visual C.
MSVC_IDE
True when using the Microsoft Visual C IDE
Set to true when the target platform is the Microsoft Visual C IDE, as
opposed to the command line compiler.
MSVC_VERSION
The version of Microsoft Visual C/C++ being used if any.
The version of Microsoft Visual C/C++ being used if any. For example
1300 is MSVC 6.0.
UNIX
True for UNIX and UNIX like operating systems.
Set to true when the target system is UNIX or UNIX like (i.e. APPLE
and CYGWIN).
WIN32
True on windows systems, including win64.
Set to true when the target system is Windows and on cygwin.
XCODE_VERSION
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 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 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.
