Re: [CMake] Ways to require CUDA arch minimum version?
Are you asking for a minimum CUDA SDK version or a restriction based on the hardware of the machine? We have no pre-built logic to enforce a minimum hardware component, as we want to support building CUDA on a machine without a GPU. As far as minimum CUDA SDK is concerned if you are doing it through find_package(CUDA) you would check the version after and error out if not high enough As farm as CUDA as a first class language, you can check the CMAKE_CUDA_COMPILER_VERSION and error out.

Thanks, I am interested in enforcing minimum computing capacity (which translates to hardware restraint). If there is no such feature, would you be interested for such a feature?

I believe that more archs would be needed in the string for better support of newer architectures, but just to get the starting point. I would have preferred if there was a better directive, similar to set(CMAKE_CXX_STANDARD 14) that can enable either C++14 or C++17 or later (depending on other components of the project) without actually harcoding c++14 and ending up with "-std=c++14 -std=c++20" in flags. For example something along the lines of set(CMAKE_CUDA_MIN_ARCH 60) Mojca -- Powered by www.kitware.com Please keep messages on-topic and check the CMake FAQ at: http://www.cmake.org/Wiki/CMake_FAQ Kitware offers various services to support the CMake community.
