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 CUDA/C++ standard level is
controlled by the :prop_tgt:`CUDA_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_CUDA_EXTENSIONS` variable if set when a target is created
and otherwise by the value of
:variable:`CMAKE_CUDA_EXTENSIONS_DEFAULT <CMAKE_<LANG>_EXTENSIONS_DEFAULT>`
(see :policy:`CMP0128`).
