<p>This causes problems since we do not then link against CUDA or OpenCL. This happens even if one passes the <code>--with-cuda=no</code> option to OpenMPI's configure script. </p>
<p>Possibly one has to follow the fix in OpenMPI's 2.x and 3.x branches to fix this: <a href="https://github.com/open-mpi/ompi/issues/4248" rel="nofollow" class="ap-connect-link">https://github.com/open-mpi/ompi/issues/4248</a></p>

<p>Comment (by Roland Haas):</p>
<p>Fixed along with #1679 when updating OpenMPI's tarball to 4.0.2.</p>
