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.
|
|
|
|
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.
|
|
|
|
This property is initialized by the value of
|
|
the :variable:`CMAKE_CXX_STANDARD` variable if it is set when a target
|
|
is created.
