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

26 .. versionadded:: 3.25

CUDA C++26. CMake 3.25 and later recognize 26 as a valid value, no version has support for any compiler.

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.
