openmpi/4.1.0 conan 2.0 package not maintained by conan-center

[jkotan]

I split this ticket from #620.

It looks like the openmpi/4.1.0 conan package is still not ready for conan 2.0

 ERROR: Package 'openmpi/4.1.0' not resolved: openmpi/4.1.0: Cannot load recipe.

https://github.com/ess-dmsc/h5cpp/actions/runs/4675291381/jobs/8280263435#step:6:102

and according to

conan-io/conan-center-index#13655

we have to wait for it much longer (if at all) or do it yourself or comment out MPI ??

The openmpi library was updated in the conan center repository but it is not recognizable by find_package() in hdf5 cmake configuration. It looks like there is ssh missing or paths not set correctly.
