| <LANG>_STANDARD_REQUIRED |
| ------------------------ |
| |
| The variations are: |
| |
| * :prop_tgt:`C_STANDARD_REQUIRED` |
| * :prop_tgt:`CXX_STANDARD_REQUIRED` |
| * :prop_tgt:`CUDA_STANDARD_REQUIRED` |
| * :prop_tgt:`HIP_STANDARD_REQUIRED` |
| * :prop_tgt:`OBJC_STANDARD_REQUIRED` |
| * :prop_tgt:`OBJCXX_STANDARD_REQUIRED` |
| |
| These properties specify whether the value of :prop_tgt:`<LANG>_STANDARD` is a |
| requirement. When ``OFF`` or unset, the :prop_tgt:`<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 |
| :variable:`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 :prop_tgt:`<LANG>_STANDARD`. |

| See the :manual:`cmake-compile-features(7)` manual for information on |
