CUDA_STANDARD

New in version 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

New in version 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

New in version 3.20.

CUDA C++23

26

New in version 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:

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 CUDA_STANDARD_REQUIRED target property. Additionally, the CUDA_EXTENSIONS target property may be used to control whether compiler-specific extensions are enabled on a per-target basis.

See the 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 CMAKE_CUDA_STANDARD variable if it is set when a target is created.
