| OBJC_EXTENSIONS |

| .. versionadded:: 3.16 |
| |
| Boolean specifying whether compiler specific extensions are requested. |
| |
| This property specifies whether compiler specific extensions should be |
| used. For some compilers, this results in adding a flag such |
| as ``-std=gnu11`` instead of ``-std=c11`` to the compile line. This |
| property is ``ON`` by default. The basic OBJC standard level is |
| controlled by the :prop_tgt:`OBJC_STANDARD` target property. |
| |
| If the property is not set, and the project has set the :prop_tgt:`C_EXTENSIONS`, |
| the value of :prop_tgt:`C_EXTENSIONS` is set for :prop_tgt:`OBJC_EXTENSIONS`. |
| |
| See the :manual:`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 :variable:`CMAKE_OBJC_EXTENSIONS` variable if set when a target is created |
| and otherwise by the value of |
| :variable:`CMAKE_OBJC_EXTENSIONS_DEFAULT <CMAKE_<LANG>_EXTENSIONS_DEFAULT>` |
| (see :policy:`CMP0128`). |
