| CMAKE_CUDA_ARCHITECTURES | |
| ------------------------ | |
| .. versionadded:: 3.18 | |
| Default value for :prop_tgt:`CUDA_ARCHITECTURES` property of targets. | |
| Initialized by the :envvar:`CUDAARCHS` environment variable if set. | |
| Otherwise as follows depending on :variable:`CMAKE_CUDA_COMPILER_ID <CMAKE_<LANG>_COMPILER_ID>`: | |
| - For ``Clang``: the oldest architecture that works. | |
| - For ``NVIDIA``: the default architecture chosen by the compiler. | |
| See policy :policy:`CMP0104`. | |
| Users are encouraged to override this, as the default varies across compilers | |
| and compiler versions. | |
| This variable is used to initialize the :prop_tgt:`CUDA_ARCHITECTURES` property | |
| on all targets. See the target property for additional information. | |
| Examples | |
| ^^^^^^^^ | |
| .. code-block:: cmake | |
| cmake_minimum_required(VERSION) | |
| if(NOT DEFINED CMAKE_CUDA_ARCHITECTURES) | |
| set(CMAKE_CUDA_ARCHITECTURES 75) | |
| endif() | |
| project(example LANGUAGES CUDA) | |
| ``CMAKE_CUDA_ARCHITECTURES`` will default to ``75`` unless overridden by the user. |
