[CMake] swig module add -fPIC flag

[CHEVRIER, Marc]

swig modules created with command SWIG_ADD_LIBRARY are "standard" CMake targets so, same approach apply.


>From convenience, you can use command SWIG_LINK_LIBRARIES (same semantic as TARGET_LINK_LIBRARIES) to manage custom link flags.


Now, regarding specifically flag -fPIC you can manage more easily and in a portable way the 'Position Independent Code' generation by setting variable CMAKE_POSITION_INDEPENDENT_CODE=ON. And I think this flag is for the compiler, not the linker...

Hi,

I have not found how to add -fPIC link flag to a SWIG module.
