[CMake] config dependent defines

[Michael Wild]

Your users will hate you for that, because they will not be able to override the compile-flags without modifying the CMakeLists.txt file.

You can set the COMPILE_DEFINITIONS_DEBUG property on individual targets using SET_TARGET_PROPERTIES() or on directories with SET_DIRECTORY_PROPERTIES.
