CMAKE_CUDA_ARCHITECTURES

New in version 3.18.


Default value for CUDA_ARCHITECTURES property of targets.

Initialized by the CUDAARCHS environment variable if set. Otherwise as follows depending on CMAKE_CUDA_COMPILER_ID:

  • For Clang: the oldest architecture that works.
  • For NVIDIA: the default architecture chosen by the compiler. See policy CMP0104.

Users are encouraged to override this, as the default varies across compilers and compiler versions.

This variable is used to initialize the CUDA_ARCHITECTURES property on all targets. See the target property for additional information.

Examples

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.
