CXX_STANDARD_REQUIRED
---------------------
Boolean describing whether the value of :prop_tgt:`CXX_STANDARD` is a requirement.
If this property is set to ``ON``, then the value of the
:prop_tgt:`CXX_STANDARD` target property is treated as a requirement. If this
property is ``OFF`` or unset, the :prop_tgt:`CXX_STANDARD` target property is
treated as optional and may "decay" to a previous standard if the requested is
not available. For compilers that have no notion of a standard level, such as
MSVC, this has no effect.
See the :manual:`cmake-compile-features(7)` manual for information on
compile features and a list of supported compilers.
This property is initialized by the value of
the :variable:`CMAKE_CXX_STANDARD_REQUIRED` variable if it is set when a
target is created.
