CXX_STANDARD.rst
CXX_STANDARD
------------
The C++ standard whose features are requested to build this target.
This property specifies the C++ standard whose features are requested
to build this target. For some compilers, this results in adding a
flag such as ``-std=gnu++11`` to the compile line. For compilers that
have no notion of a standard level, such as MSVC, this has no effect.
Supported values are ``98``, ``11`` and ``14``.
If the value requested does not result in a compile flag being added for
the compiler in use, a previous standard flag will be added instead. This
means that using:
.. code-block:: cmake
set_property(TARGET tgt PROPERTY CXX_STANDARD 11)
with a compiler which does not support ``-std=gnu++11`` or an equivalent
flag will not result in an error or warning, but will instead add the
``-std=gnu++98`` flag if supported. This "decay" behavior may be controlled
with the :prop_tgt:`CXX_STANDARD_REQUIRED` target property.
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` variable if it is set when a target
is created.
