C_STANDARD_REQUIRED | |
------------------- | |
.. versionadded:: 3.1 | |
Boolean describing whether the value of :prop_tgt:`C_STANDARD` is a requirement. | |
If this property is set to ``ON``, then the value of the | |
:prop_tgt:`C_STANDARD` target property is treated as a requirement. If this | |
property is ``OFF`` or unset, the :prop_tgt:`C_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 C standard level, such | |
as Microsoft Visual C++ before VS 16.7, this property 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_C_STANDARD_REQUIRED` variable if it is set when a | |
target is created. |
