Yes, if I add --with-hdf5-includedir=/usr/include/mpi. If not I get
the same "HDF5 library not found."

Or is it any hdf5 variant? Have you tried installing the non-openmpi
libhdf5-7 with the original octave packages to see if that also
crashes on you? I didn't see whether you had tried that yet.

Answered above. Basically because hdf5 does not use pkg-config and its
public header files have dependencies on the mpi headers.
