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.
