Hi Jan, Unfortunately, I cannot help you in this regard, though I am surprised how little attention this question gained. I too feel that CMake could do better both in this regard. While ABI detection is very well done, BUILD_TYPE seems to be the only compiler agnostic option available. I do not know how to set warning levels for eg. in a compiler agnostic manner. Aside from this, there are dozens of other options that are common to all C++ compilers and it would rock if I need not look up the exact params for all of them.
Sorry I could not help, but I do feel the struggle.

Its about Fortran projects, where I e.g. want to explicitly enable the preprocessor, or make all default real values 8 byte wide. This could be done as such: if(${CMAKE_Fortran_COMPILER_ID} STREQUAL "Intel") set(CMAKE_Fortran_FLAGS "-fpp -r8") elseif(${CMAKE_Fortran_COMPILER_ID} STREQUAL "GNU") set(CMAKE_Fortran_FLAGS "-cpp -fdefault-real-8") endif() Cmake has the cmake-compile-features and I though maybe some similar mechanism exists for above mentioned compiler switches. So I could say target_compile_features(mylib PRIVATE f_preprocessor f_real_8) Thanks for sharing your advise, Jan -- Powered by www.kitware.com Please keep messages on-topic and check the CMake FAQ at: http://www.cmake.org/Wiki/CMake_FAQ Kitware offers various services to support the CMake community.
