| target_compile_options |
| ---------------------- |
| |
| Add compile options to a target. |
| |
| .. code-block:: cmake |
| |
| target_compile_options(<target> [BEFORE] |
| <INTERFACE|PUBLIC|PRIVATE> [items1...] |
| [<INTERFACE|PUBLIC|PRIVATE> [items2...] ...]) |
| |
| Adds options to the :prop_tgt:`COMPILE_OPTIONS` or |
| :prop_tgt:`INTERFACE_COMPILE_OPTIONS` target properties. These options |
| are used when compiling the given ``<target>``, which must have been |
| created by a command such as :command:`add_executable` or |
| :command:`add_library` and must not be an :ref:`ALIAS target <Alias Targets>`. |
| |
| Arguments |
| ^^^^^^^^^ |
| |
| If ``BEFORE`` is specified, the content will be prepended to the property |
| instead of being appended. |
| |
| 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. |
| |
| .. versionadded:: 3.11 |
| Allow setting ``INTERFACE`` items on :ref:`IMPORTED targets <Imported Targets>`. |
| |
| 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. |

| |
| This command can be used to add any options. However, for adding |
| preprocessor definitions and include directories it is recommended |
| to use the more specific commands :command:`target_compile_definitions` |
| and :command:`target_include_directories`. |
| |
| For directory-wide settings, there is the command :command:`add_compile_options`. |
| |
| For file-specific settings, there is the source file property :prop_sf:`COMPILE_OPTIONS`. |
