Markus:

Probably we can only loop over common directories and check
if the epsg file is there unless a new proj-config becomes
available and distributed?

As probably 4 values will cover 90% of users, I think this is a
practical solution. I don't plan on adding a request for proj-config,
if someone else thinks it is a good idea please add the wish.
