| <LANG>_EXTENSIONS |
| ----------------- |
| |
| The variations are: |
| |
| * :prop_tgt:`C_EXTENSIONS` |
| * :prop_tgt:`CXX_EXTENSIONS` |
| * :prop_tgt:`CUDA_EXTENSIONS` |
| * :prop_tgt:`HIP_EXTENSIONS` |
| * :prop_tgt:`OBJC_EXTENSIONS` |
| * :prop_tgt:`OBJCXX_EXTENSIONS` |
| |
| These properties specify whether compiler-specific extensions are requested. |
| |
| These properties are initialized by the value of the |
| :variable:`CMAKE_<LANG>_EXTENSIONS` variable if it is set when a target is |
| created and otherwise by the value of |
| :variable:`CMAKE_<LANG>_EXTENSIONS_DEFAULT` (see :policy:`CMP0128`). |
| |
| 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 |
| compile features and a list of supported compilers. |
