- fix libproj detection: Our graphics proj is built with autotools and thus
does not install it's cmake files. Patches provide an alternate method
for finding libproj using pkg-config, see:
https://sourceforge.net/p/qlandkartegt/mailman/message/36639866/
- fix a crash with current Qt when no GPS device is found (which at least for
me is the default case): since the last Qt update, QList aborts on an
assertion when trying to access the first element of an empty list.
