Hello,

following this is a patch to add gromacs.

Description & synopsis taken from nix (hello Tobias)

Linted, indent-code.el passed, and built OK with 2 rounds.

Not sure if we want more cmake flags.

problems reported by cmake:

(found version "1.8.15") found components:  doxygen missing components:  dot

-- Could NOT find Sphinx: Found unsuitable version "-real 2.3.1", but 
required is at least "1.6.1" (found
