target_compile_options ---------------------- Add compile options to a target. :: target_compile_options( [BEFORE] [items1...] [ [items2...] ...]) Specify compile options to use when compiling a given target. The named ```` must have been created by a command such as :command:`add_executable` or :command:`add_library` and must not be an :prop_tgt:`IMPORTED Target`. 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_tgt:`directory ` and :prop_tgt:` target ` ``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 ````. ``PUBLIC`` and ``INTERFACE`` items will populate the :prop_tgt:`INTERFACE_COMPILE_OPTIONS` property of ````. The following arguments specify compile options. Repeated calls for the same ```` 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.
