Feature request: linking to hdf5 in mkmf.templates for Derecho

[hkershaw-brown]

Use case

Building any of the various DART programs that require hdf5

Is your feature request related to a problem?

Derecho has a newer version of hdf5 (1.12.2)compared to Cheyenne, and the name of one of the libraries has changed.

Instead of -lhdf5hl_fortran its -lhdf5_hl_fortran

Describe your preferred solution

• Update the rttov mkmf.templates mkmf.template.rttov.gfortran mkmf.template.rttov.intel

  with a comment to use -lhdf5hl_fortran if you are using an older version of hf5 (note to self: look up which version has the change).

• Add note in rttov docs about linking to hdf

Describe any alternatives you have considered

None

looks like 1.15 goes back to lhdf5hl_fortran https://docs.hdfgroup.org/hdf5/develop/_l_b_compiling.html
