I would suggest switching to the MakeCp easyblock -- that way, we don't need to patch the makefile. Instead, something like:

files_to_copy = [
    (['vampire-serial', 'vampire-parallel', 'util/vdc/vdc'], 'bin'),
    (['input', 'Co.mat'], 'examples'),
    'license', 'BSD_licence', 'readme.md',
]

would do the trick
