OBJC_STANDARD_REQUIRED

Boolean describing whether the value of OBJC_STANDARD is a requirement.

If this property is set to ON, then the value of the OBJC_STANDARD target property is treated as a requirement. If this property is OFF or unset, the OBJC_STANDARD target property is treated as optional and may “decay” to a previous standard if the requested is not available.

If the property is not set, and the project has set the C_STANDARD_REQUIRED, the value of C_STANDARD_REQUIRED is set for OBJC_STANDARD_REQUIRED.

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_OBJC_STANDARD_REQUIRED variable if it is set when a target is created.
