# - 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")
