OBJCXX_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=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 ``OBJCXX_EXTENSIONS``.
|
|
|
|
This property is initialized by the value of
|
|
the :variable:`CMAKE_OBJCXX_EXTENSIONS` variable if set when a target is
|
|
created and otherwise by the value of
|
|
:variable:`CMAKE_OBJCXX_EXTENSIONS_DEFAULT <CMAKE_<LANG>_EXTENSIONS_DEFAULT>`
|
|
(see :policy:`CMP0128`).
