<LANG>_STANDARD_REQUIRED

The variations are:

• C_STANDARD_REQUIRED

• CXX_STANDARD_REQUIRED

• CUDA_STANDARD_REQUIRED

• HIP_STANDARD_REQUIRED

• OBJC_STANDARD_REQUIRED

• OBJCXX_STANDARD_REQUIRED

These properties specify whether the value of <LANG>_STANDARD is a requirement. When OFF or unset, the <LANG>_STANDARD target property is treated as optional and may "decay" to a previous standard if the requested is not available.

These properties are initialized by the value of the CMAKE_<LANG>_STANDARD_REQUIRED variable if it is set when a target is created.

For supported CMake versions see the respective pages. To control language standard versions see <LANG>_STANDARD.

See the cmake-compile-features(7) manual for information on compile features and a list of supported compilers.
