I didn't follow this discussion closely enough. I'll see if I can catch up with it later.

    Setting CMAKE_CXX_FLAGS is not 'modern cmake'. Prefer to use add_compile_options instead.

    add_compiler_export_flags() should not be used at all.
    
     http://cmake.org/gitweb?p=cmake.git;a=commitdiff;h=0f3a66673f
    
    set CMAKE_CXX_VISIBILITY_PRESET and CMAKE_VISIBILITY_INLINES_HIDDEN instead.
