Dolfinx via spack fails due to HDF5 serial build

I’m trying to install dolfinx using spack on a zen2 machine with CentOS7 using the instructions here everything appears to work well until the cmake stage for dolfinx. The installation of hdf5 has apparently been configured and installed for serial computation, despite parallel being the default.

I can compile and install my own local version of HDF5 with --parallel-enabled which works well and proceed, but it’s puzzling why the spack build fails. Is there something stupid I’m doing?

I’m certain my PATH, LD_LIBRARY_PATH and CMAKE_PREFIX_PATH are clean when using spack.

Fixed in #1677.

Thanks @garth.
