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.
