Check out

Here's an example of how I use it in my project:

        # If this buildable needs to modify CMAKE_CXX_FLAGS*, it will
        # create a macro to handle the modifications.
        if (COMMAND ${PROJECT_NAME}_compiler_linker_flags)
            # We would like to just call
            # ${PROJECT_NAME}_compiler_linker_flags () here, but we
            # can't do it directly. This workaround accomplishes the
            # same thing. See
            # http://www.cmake.org/Wiki/CMake/Language_Syntax#Substitution_of_command_names.
            file (WRITE
                "${CMAKE_CURRENT_BINARY_DIR}/${PROJECT_NAME}_complier_linker_flags.cmake"
                "${PROJECT_NAME}_compiler_linker_flags ()"
            )
            include ("${CMAKE_CURRENT_BINARY_DIR}/${PROJECT_NAME}_complier_linker_flags.cmake")
        endif ()
