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.
