CUDA_STANDARD
-------------
.. versionadded:: 3.8
The CUDA/C++ standard whose features are requested to build this target.
This property specifies the CUDA/C++ standard whose features are requested
to build this target. For some compilers, this results in adding a
flag such as ``-std=gnu++11`` to the compile line.
Supported values are:
``98``
CUDA C++98. Note that this maps to the same as ``03`` internally.
``03``
CUDA C++03
``11``
CUDA C++11
``14``
CUDA C++14. While CMake 3.8 and later *recognize* ``14`` as a valid value,
CMake 3.9 was the first version to include support for any compiler.
``17``
CUDA C++17. While CMake 3.8 and later *recognize* ``17`` as a valid value,
CMake 3.18 was the first version to include support for any compiler.
``20``
.. versionadded:: 3.12
CUDA C++20. While CMake 3.12 and later *recognize* ``20`` as a valid value,
CMake 3.18 was the first version to include support for any compiler.
``23``
.. versionadded:: 3.20
CUDA C++23
If the value requested does not result in a compile flag being added for
the compiler in use, a previous standard flag will be added instead. This
means that using:
.. code-block:: cmake
set_property(TARGET tgt PROPERTY CUDA_STANDARD 11)
with a compiler which does not support ``-std=gnu++11`` or an equivalent
flag will not result in an error or warning, but will instead add the
``-std=gnu++03`` flag if supported. This "decay" behavior may be controlled
with the :prop_tgt:`CUDA_STANDARD_REQUIRED` target property.
Additionally, the :prop_tgt:`CUDA_EXTENSIONS` target property may be used to
control whether compiler-specific extensions are enabled on a per-target basis.
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_STANDARD` variable if it is set when a target
is created.
