- 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>``.
- (:ref:`IMPORTED targets <Imported Targets>` only support ``INTERFACE`` items.)
- 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
- :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.
