<LANG>_STANDARD_REQUIRED
|
|
------------------------
|
|
|
|
The variations are:
|
|
|
|
* :prop_tgt:`C_STANDARD_REQUIRED`
|
|
* :prop_tgt:`CXX_STANDARD_REQUIRED`
|
|
* :prop_tgt:`CUDA_STANDARD_REQUIRED`
|
|
* :prop_tgt:`HIP_STANDARD_REQUIRED`
|
|
* :prop_tgt:`OBJC_STANDARD_REQUIRED`
|
|
* :prop_tgt:`OBJCXX_STANDARD_REQUIRED`
|
|
|
|
These properties specify whether the value of :prop_tgt:`<LANG>_STANDARD` is a
|
|
requirement. When false or unset, the :prop_tgt:`<LANG>_STANDARD` target
|
|
property is treated as optional and may "decay" to a previous standard if the
|
|
requested standard is not available. When ``<LANG>_STANDARD_REQUIRED`` is set
|
|
to true, :prop_tgt:`<LANG>_STANDARD` becomes a hard requirement and a fatal
|
|
error will be issued if that requirement cannot be met.
|
|
|
|
Note that the actual language standard used may be higher than that specified
|
|
by :prop_tgt:`<LANG>_STANDARD`, regardless of the value of
|
|
``<LANG>_STANDARD_REQUIRED``. In particular,
|
|
:ref:`transitive usage requirements <Target Usage Requirements>` or the use of
|
|
:manual:`compile features <cmake-compile-features(7)>` can raise the required
|
|
language standard above what :prop_tgt:`<LANG>_STANDARD` specifies.
|
|
|
|
These properties are initialized by the value of the
|
|
:variable:`CMAKE_<LANG>_STANDARD_REQUIRED` variable if it is set when a target
|
|
is created.
|
|
|
|
See the :manual:`cmake-compile-features(7)` manual for information on
|
|
compile features and a list of supported compilers.
