[CMake] Setting CMAKE_CXX_FLAGS..., CMAKE_C_FLAGS... and CMAKE_C_STANDARD_LIBRARIES_INIT and friends on a per target basis

[Verweij, Arjen]

Hi Brian,

We override the standard CMAKE_<LANG>_FLAGS (C CXX Fortran) and use it as a baseline. Then, for individual source files it is possible to override them in a separate file using:

set_source_files_properties(${CMAKE_BINARY_DIR}/path/to/file.f PROPERTIES GENERATED TRUE COMPILE_FLAGS "${FFLAG_OPT}")

These override files are included OPTIONALly and the directives executed when applicable.

Regards,
Arjen

CMAKE_CXX_FLAGS..., CMAKE_C_FLAGS... and CMAKE_C_STANDARD_LIBRARIES_INIT and friends are seemingly global variables.  Is there a way to override (all of) these on a per target basis?  A method which is not tied to the directory (properties). One that does not simply append such as COMPILE_FLAGS, but blasts away and makes it what I specify? Basically all the goop in Windows-icl.cmake, Windows-cl.cmake, etc.  Possibly involving set_target_properties?
