# CMAKE_CUDA_KNOWN_FEATURES

Added in version 3.17.

List of CUDA features known to this version of CMake.

The features listed in this global property may be known to be available to the CUDA compiler. If the feature is available with the C++ compiler, it will be listed in the `CMAKE_CUDA_COMPILE_FEATURES` variable.

The features listed here may be used with the `target_compile_features()` command. See the `cmake-compile-features(7)` manual for information on compile features and a list of supported compilers.

The features known to this version of CMake are:

`cuda_std_03`

  Compiler mode is at least CUDA/C++ 03.

`cuda_std_11`

  Compiler mode is at least CUDA/C++ 11.

`cuda_std_14`

  Compiler mode is at least CUDA/C++ 14.

`cuda_std_17`

  Compiler mode is at least CUDA/C++ 17.

`cuda_std_20`

  Compiler mode is at least CUDA/C++ 20.

`cuda_std_23`

  Added in version 3.20.

  Compiler mode is at least CUDA/C++ 23.

`cuda_std_26`

  Added in version 3.30.

  Compiler mode is at least CUDA/C++ 26.

Note

If the compiler's default standard level is at least that of the requested feature, CMake may omit the `-std=` flag. The flag may still be added if the compiler's default extensions mode does not match the `<LANG>_EXTENSIONS` target property, or if the `<LANG>_STANDARD` target property is set.
