Thanks for your help! Do we probably also need to define

LOC_CHECK_SHARE_PATH(proj,External PROJ.4,PROJSHARE)

LOC_CHECK_SHARE(epsg,External PROJ.4,$PROJSHARE)

If not, I don't know how to figure out PROJSHARE (which I then need in
include/Make/Platform.make[.in]. If yes, would you mind to write those?

thanks
