I think you hit this issue in clang: https://reviews.llvm.org/D89752

Also note nvidia-smi shows the CUDA driver API version, it's not the CUDA toolkit version. But both seem to be 11.4 in this case.

You say you have Cuda 11.4, but the error message says:

Maybe you have multiple cuda versions installed?

I think that when you first configure the cmake build, you can use -DCUDA_TOOLKIT_ROOT_DIR=... to point it at a particular Cuda install.
