Mikael Simberg fa9fb60df3 CachedCMakePackage: fix bug where CMAKE_CUDA_ARCHITECTURES=none is set (#38169) ... #37592 updated cached cmake packages to set CMAKE_CUDA_ARCHITECTURES. The condition `if archs != "none"` lead to `CMAKE_CUDA_ARCHITECTURES=none` when cuda_arch=none (incorrect check on the value of a multi-valued variant), i.e. CMAKE_CUDA_ARCHITECTURES is always set. This PR udpates the condition to if archs[0] != "none" to ensure CMAKE_CUDA_ARCHITECTURES is only set if cuda_arch is not none (which seems to be the pattern used in other packages). This does the same for HIP (although in general ROCmPackage disallows amdgpu_target=none when +rocm).		2023-06-06 14:41:02 -07:00
