CXX_EXTENSIONS
--------------

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.

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_CXX_EXTENSIONS` variable if it is set when a target
is created.
cmTarget: Add CXX_STANDARD and CXX_EXTENSION target properties. These are used to determine whether to add -std=c++11, -std=gnu++11 etc flags on the compile line. 2013-10-13 00:00:24 +00:00			`CXX_EXTENSIONS`

Features: Enable compiler extensions by default. Compilers enable their extensions by default, and disabling them implicitly can lead to results which are surprising or non-obvious to debug. http://public.kitware.com/pipermail/cmake-developers/2014-May/010575.html http://thread.gmane.org/gmane.comp.programming.tools.cmake.devel/10214 https://www.mail-archive.com/cmake-developers@cmake.org/msg10116.html (Compiler feature extensions by default, 29 May 2014) 2014-05-30 13:03:45 +00:00			as ``-std=gnu++11`` instead of ``-std=c++11`` to the compile line.
