target_compile_definitions -------------------------- Add compile definitions to a target. :: target_compile_definitions(<target> <INTERFACE|PUBLIC|PRIVATE> [items1...] [<INTERFACE|PUBLIC|PRIVATE> [items2...] ...]) Specify compile definitions to use when compiling a given ``<target>``. The named ``<target>`` must have been created by a command such as :command:`add_executable` or :command:`add_library` and must not be an :ref:`Imported Target <Imported Targets>`. The ``INTERFACE``, ``PUBLIC`` and ``PRIVATE`` keywords are required to specify the scope of the following arguments. ``PRIVATE`` and ``PUBLIC`` items will populate the :prop_tgt:`COMPILE_DEFINITIONS` property of ``<target>``. ``PUBLIC`` and ``INTERFACE`` items will populate the :prop_tgt:`INTERFACE_COMPILE_DEFINITIONS` property of ``<target>``. The following arguments specify compile definitions. Repeated calls for the same ``<target>`` append items in the order called. Arguments to ``target_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.
