 It looks like nVidia’s MTT started failing on 9/26, due to not finding 
 Cuda.  There’s a suspicious commit given the error message in the hwloc 
 cuda changes.  Jeff and Brice, it’s your patch, can you dig into the build 
 failures?

Re: [OMPI devel] Cuda build break

[Sylvain Jeaugey]

See my last comment on #4257 :

https://github.com/open-mpi/ompi/pull/4257#issuecomment-332900393

We should completely disable CUDA in hwloc. It is breaking the build, 
but more importantly, it creates an extra dependency on the CUDA runtime 
that Open MPI doesn't have, even when compiled with --with-cuda (we load 
symbols dynamically).
