| |
| 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 C standard level is |
| controlled by the :prop_tgt:`C_STANDARD` target property. |
| |
| 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_C_EXTENSIONS` variable if it is set when a target |
| is created. |
