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>`. If ``BEFORE`` is specified, +the content will be prepended to the property instead of being appended. + +This command can be used to add any options, but +alternative commands exist to add preprocessor definitions +(:command:`target_compile_definitions` and :command:`add_definitions`) or +include directories (:command:`target_include_directories` and +:command:`include_directories`). See documentation of the +:prop_dir:`directory <COMPILE_OPTIONS>` and +:prop_tgt:`target <COMPILE_OPTIONS>` ``COMPILE_OPTIONS`` properties. + +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_OPTIONS` property of +``<target>``. ``PUBLIC`` and ``INTERFACE`` items will populate the +:prop_tgt:`INTERFACE_COMPILE_OPTIONS` property of ``<target>``. The +following arguments specify compile options. Repeated calls for the same +``<target>`` append items in the order called. + +Arguments to ``target_compile_options`` 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. |
