| target_compile_features | |
| ----------------------- | |
| .. versionadded:: 3.1 | |
| Add expected compiler features to a target. | |
| .. code-block:: cmake | |
| target_compile_features(<target> <PRIVATE|PUBLIC|INTERFACE> <feature> [...]) | |
| Specifies compiler features required when compiling a given target. If the | |
| feature is not listed in the :variable:`CMAKE_C_COMPILE_FEATURES`, | |
| :variable:`CMAKE_CUDA_COMPILE_FEATURES`, or :variable:`CMAKE_CXX_COMPILE_FEATURES` | |
| variables, then an error will be reported by CMake. If the use of the feature requires | |
| an additional compiler flag, such as ``-std=gnu++11``, the flag will be added | |
| automatically. | |
| The ``INTERFACE``, ``PUBLIC`` and ``PRIVATE`` keywords are required to | |
| specify the scope of the features. ``PRIVATE`` and ``PUBLIC`` items will | |
| populate the :prop_tgt:`COMPILE_FEATURES` property of ``<target>``. | |
| ``PUBLIC`` and ``INTERFACE`` items will populate the | |
| :prop_tgt:`INTERFACE_COMPILE_FEATURES` property of ``<target>``. | |
| Repeated calls for the same ``<target>`` append items. | |
| .. versionadded:: 3.11 | |
| Allow setting ``INTERFACE`` items on :ref:`IMPORTED targets <Imported Targets>`. | |
| 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:`ALIAS target <Alias Targets>`. | |
| Arguments to ``target_compile_features`` may use "generator expressions" | |
| with the syntax ``$<...>``. | |
| See the :manual:`cmake-generator-expressions(7)` manual for available | |
| expressions. See the :manual:`cmake-compile-features(7)` manual for | |
| information on compile features and a list of supported compilers. |
