PR #134713, which landed as 79cb6f05da37, causes this on my test systems: ``` -- Building AMDGPU plugin for dlopened libhsa -- Not generating AMDGPU tests, no supported devices detected. Use 'LIBOMPTARGET_FORCE_AMDGPU_TESTS' to override. -- Building CUDA plugin for dlopened libcuda -- Not generating NVIDIA tests, no supported devices detected. Use 'LIBOMPTARGET_FORCE_NVIDIA_TESTS' to override. ``` The problem is it cannot locate amdgpu-arch and nvptx-arch. This patch enables it to. I suspect there is more cleanup to do here. amdgpu-arch and nvptx-arch do not appear to exist as cmake targets anymore, but there is still cmake code here that looks for those targets.
