Explain that this represents the compiler's default and mustn't be modified by the user. Clarify when it's used as the default. Additionally: * Add a reference to it in cmake-compile-features in text explaining the feature. * Add explanations for the default initialization by `CMAKE_<LANG>_EXTENSIONS_DEFAULT` to all `<LANG>_EXTENSIONS` pages and references to CMP0128. * Slightly reduce the wordiness of the default initialization explanations by removing an unnecessary "it is". Fixes #22828.

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`).
