[CMake] Set different compilation flags for specific file

[Rob Mathews]

No that doesn't work. 

Well ... you could start out by setting CMAKE_CXX_FLAGS_RELEASE to ""
and then using the SET_SOURCE_FILES_PROPERTIES to add the flags you need
to every file .. the file that 

SET(CMAKE_CXX_FLAGS_RELEASE_SAVED ${CMAKE_CXX_FLAGS_RELEASE}  )
SET(CMAKE_CXX_FLAGS_RELEASE ""  )

then for more of the files do this: 

SET_SOURCE_FILES_PROPERTIES COMPILE_FLAGS ${CMAKE_CXX_FLAGS_RELEASE}) 

except for the one file where you want the special flags: 
SET_SOURCE_FILES_PROPERTIES COMPILE_FLAGS "special set of flags")


and then restore CMAKE_CXX_FLAGS_RELEASE for the rest of the system
build: 

SET(CMAKE_CXX_FLAGS_RELEASE ${CMAKE_CXX_FLAGS_RELEASE_SAVED}  )

So I can't set this for a single source file, but rather a library?

Can I add additional sources to the library after I added the library:

ADD_LIBRARY(mylib ${other_sources})
SET(CMAKE_CXX_FLAGS_RELEASE_SAVED ${CMAKE_CXX_FLAGS_RELEASE}  )
SET(CMAKE_CXX_FLAGS_RELEASE "/MT /Ox /Ob1 /DNDEBUG"  )
ADD_LIBRARY(mylib ${special_file})
SET(CMAKE_CXX_FLAGS_RELEASE ${CMAKE_CXX_FLAGS_RELEASE_SAVED}  )

This didn't seem to work.
