Definitions with non-trivial values +may be left in the set of flags instead of being converted for reasons of +backwards compatibility. See documentation of the +:prop_dir:`directory <COMPILE_DEFINITIONS>`, +:prop_tgt:`target <COMPILE_DEFINITIONS>`, +:prop_sf:`source file <COMPILE_DEFINITIONS>` ``COMPILE_DEFINITIONS`` +properties for details on adding preprocessor definitions to specific +scopes and configurations. + +See the :manual:`cmake-buildsystem(7)` manual for more on defining +buildsystem properties. |
