Hello,

In support of the recent ongoing efforts to implement [OpenACC in Clang/LLVM](https://discourse.llvm.org/t/rfc-implementation-of-openacc-3-3-for-offload-in-clang/74405), Given LLVM’s utilization of CMake, we want to add support for the LLVM/Clang compiler in the OpenACC module.

This would be highly used, especially when we include the [OpenACC Testsuite](https://github.com/OpenACCUserGroup/OpenACCV-V) to the llvm-test-suite, which also uses CMake.

Similar to the compilers already supported, we see the only addition to the CMake code is within the FindOpenACC.cmake file, where we set ACC\_FLAG\_Clang.

Comments are welcome!

Thanks,  
Aaron

@ajarmusch yes, one should only need to fill out the table in FindOpenACC. Please see the [contribution guide](https://gitlab.kitware.com/cmake/cmake/blob/master/CONTRIBUTING.rst). Thanks!
