They are also added to +the :prop_tgt:`COMPILE_DEFINITIONS` target property for each target in the +current ``CMakeLists`` file. + +Definitions are specified using the syntax ``VAR`` or ``VAR=value``. +Function-style definitions are not supported. CMake will automatically +escape the value correctly for the native build system (note that CMake +language syntax may require escapes to specify some values). + +Arguments to ``add_compile_definitions`` may use "generator expressions" with +the syntax ``$<...>``. See the :manual:`cmake-generator-expressions(7)` +manual for available expressions. See the :manual:`cmake-buildsystem(7)` +manual for more on defining buildsystem properties. |
