CXX_STANDARD_REQUIRED

CXX_STANDARD_REQUIRED

Boolean describing whether the value of CXX_STANDARD is a requirement.

If this property is set to ON, then the value of the CXX_STANDARD target property is treated as a requirement. If this property is OFF or unset, the 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 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 CMAKE_CXX_STANDARD_REQUIRED variable if it is set when a target is created.
