Cmake: how to force including more than one header

Question

Hi,

I try to force including header with CMake(2.8.2) and this first solution:

   SET_TARGET_PROPERTIES(${MyTarget} PROPERTIES COMPILE_FLAGS "/FI\"${ForcedHeader_A}\"/FI\"${ForcedHeader_B}\"")

Somehow CMake ignores (or overwrites) the first compiler flag. This happens only if the two compiler flags are the same as in this case . I have to port something I dont want to modify the software structure at this moment. Can anyone help me ?

Thanks

Try this (note also that recent CMake means you don't need to USE_CAPS_ALL_THE_TIME):

get_target_property(FLAGS ${MyTarget} COMPILE_FLAGS)
set_target_properties(${MyTarget} PROPERTIES COMPILE_FLAGS "${FLAGS} /FI\"${ForcedHeader_A}\"/FI\"${ForcedHeader_B}\"")
