 # - 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")
