For some compilers, this results in adding a flag such +as ``-std=gnu++11`` instead of ``-std=c++11`` to the compile line. This +property is ``ON`` by default. The basic ObjC++ standard level is +controlled by the :prop_tgt:`OBJCXX_STANDARD` target property. + +See the :manual:`cmake-compile-features(7)` manual for information on +compile features and a list of supported compilers. + +If the property is not set, and the project has set the :prop_tgt:`CXX_EXTENSIONS`, +the value of :prop_tgt:`CXX_EXTENSIONS` is set for :prop_tgt:`OBJCXX_EXTENSIONS`. + +This property is initialized by the value of +the :variable:`CMAKE_OBJCXX_EXTENSIONS` variable if it is set when a target +is created. |
