Lib zint not found

[Timbo]

I followed the sample build instructions at:-
https://github.com/jimevins/glabels-qt/blob/master/docs/BUILD-INSTRUCTIONS-LINUX.md
which went without a hitch.

However when I try to run glabels-qt it errors with:-
glabels-qt: error while loading shared libraries: libzint.so.2.6: cannot open shared object file: No such file or directory

After much furtling around and consulting Google it transpired that although the library files were in the correct place
in /usr/local/lib a sudo ldconfig was required to update the cache (a reboot didn't suffice). Perhaps this step should be added to your guide.
