target_compile_features
-----------------------

.. versionadded:: 3.1

Add expected compiler features to a target.

.. code-block:: cmake

  target_compile_features(<target>
    {INTERFACE|PUBLIC|PRIVATE} <feature>...
    [{INTERFACE|PUBLIC|PRIVATE} <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`, :variable:`CMAKE_CXX_COMPILE_FEATURES`,
or :variable:`CMAKE_SYCL_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`.

.. versionchanged:: 4.5
  If ``<target>`` is an :ref:`Alias Target <Alias Targets>`, the command
  operates on the target which the alias references.
