I just discovered nice feature: COMPILE_DEFINITIONS property.
That is you can add custom defines to source files, targets or directories (with 
commands set_source_files_properties, set_target_properties and 
set_directory_properties commands accordingly).

Moreover, COMPILE_DEFINITIONS can be configuration-specific, like 
COMPILE_DEFINITIONS_DEBUG.
