for the n-th time: This is not an officially supported Clang version. 
Trunk does not yet support offloading to Nvidia GPUs, see 

Regarding your problem: This repository does not exist or I'm also 
unable to find it. I think libomptarget is now integrated into the 
openmp repository, you might need to enable it with a CMake flag.
