Use CMAKE_<LANG>_COMPILER_LOADED to determine which languages are enabled. Then check both C and CXX compilers. If the results are the same then you can just write the header normally. Otherwise write the header with #ifdef __cplusplus to distinguish the two compilers. -Brad -- Powered by www.kitware.com Visit other Kitware open-source projects at http://www.kitware.com/opensource/opensource.html Please keep messages on-topic and check the CMake FAQ at: http://www.cmake.org/Wiki/CMake_FAQ Follow this link to subscribe/unsubscribe: http://public.kitware.com/cgi-bin/mailman/listinfo/cmake-developers
