I think you can use same way of configuration-specific flags as for linker 
(that is CMAKE_CXX_FLAGS_DEBUG, CMAKE_CXX_FLAGS_MINSIZEREL, 
CMAKE_CXX_FLAGS_RELEASE)

But this way you can set them on per-source basis.

CMake is great tool, which allows you customize build in may ways (It seems so 
at least :) ).
In my project, I had to use specific flags only for some sources but in all 
configurations.

Look at advanced variables provided by CMakeSetup.exe or ccmake. It appears 
sometimes useful for me to turn off optimization in RelWithDebInfo build type 
(I need release version msvcrt dlls), And in CMakeSetup I can set it with one 
simple change in hundred of projects.

I suppose these flags should help you, and affect 
(project+configuration)-specific compiler options in Visual Studio.
