| target_compile_features |
| ----------------------- |
| |
| Add expected compiler features to a target. |
| |
| :: |
| |
| target_compile_features(<target> <PRIVATE|PUBLIC|INTERFACE> <feature> [...]) |
| |
| Specify compiler features required when compiling a given target. If the |
| feature is not listed in the :variable:`CMAKE_C_COMPILE_FEATURES` variable |
| or :variable:`CMAKE_CXX_COMPILE_FEATURES` variable, |
| 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. |
| |
| The named ``<target>`` must have been created by a command such as |
| :command:`add_executable` or :command:`add_library` and must not be |
| an ``IMPORTED`` target. |
| |
| 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. |
