Comment (by Veence):

 Ok, there are still some glitches to solve.

 First off, I updated the QWT port so that QWT61 is built with Qt5 by
 default, so it can be pulled in by the automatic build process. Added some
 code to check QWT 6.1 is installed with the correct variant. Updated
 various dependencies too.

 Removed the grass70 → grass72 patch as this is taken care of in the newest
 version.

 Will commit later today. Let’s see what happens.
