Some similar changes to support non-standard HDF5 install paths were
already made upstream some time ago but have not been verified nor
released yet. See upstream bug #38928 [1]. I plan on testing
upstream's development branch with the hdf5 experimental packages to
see whether it is sufficient or whether these patches are also needed.
I'll report back here and on the upstream bug report with my findings.

So installing a parallel version of the library will neither hurt nor
help Octave's use of HDF5? And -dev packages can be co-installed?
Sounds good to me. Has my patch to hdf5 to bypass the C++ MPI API been
reverted, it sounds like it is no longer needed (and was introduced in
the context of Octave).
