Oh the embarassment. I remember the built having failed because the compiler did not know `-gmlt`. I searched for the flang and found a post that mentioned Google. Now I think it was because CMake selected gcc over clang. Would need to set the environment variables CXX/CC to override on a platform where gcc is the default compiler.

I appreciate your patience.
