hwloc in OpenMPI self-built code uses CUDA and OpenCL
Issue #2205
new
This causes problems since we do not then link against CUDA or OpenCL. This happens even if one passes the --with-cuda=no
option to OpenMPI's configure script.
Possibly one has to follow the fix in OpenMPI's 2.x and 3.x branches to fix this: https://github.com/open-mpi/ompi/issues/4248
