2 # Defines the following macros:
3 # SWIG_ADD_MODULE(name language [ files ])
4 # - Define swig module with given name and specified language
5 # SWIG_LINK_LIBRARIES(name [ libraries ])
6 # - Link libraries to swig module
7 # All other macros are for internal use only.
8 # To get the actual name of the swig module,
9 # use: ${SWIG_MODULE_name_REAL_NAME}.
10 # Set Source files properties such as CPLUSPLUS and SWIG_FLAGS to specify
11 # special behavior of SWIG. Also global CMAKE_SWIG_FLAGS can be used to add
12 # special flags to all swig calls.
13 # Another special variable is CMAKE_SWIG_OUTDIR, it allows one to specify
14 # where to write all the swig generated module (swig -outdir option)
15 # The name-specific variable SWIG_MODULE_<name>_EXTRA_DEPS may be used
16 # to specify extra dependencies for the generated modules.
