Merge lp://staging/~widelands-dev/widelands/update_appveyor into lp://staging/widelands

Continuous integration builds have changed state:

Travis build 4220. State: passed. Details: https://travis-ci.org/widelands/widelands/builds/454562130.
Appveyor build 4016. State: failed. Details: https://ci.appveyor.com/project/widelands-dev/widelands/build/_widelands_dev_widelands_update_appveyor-4016.

I'm wondering whether InnoSetup supports wildcards. If we could specify the .dlls as "libfluidsynth-?.dll" etc, there would be less maintenance needed for changes on AppVeyor.

Yes, but this still would require to identify dlls in the first place. Just tested, and now we need some more dlls. (e.g. the famous libreadline7.dll ;) ).

Static linking would be the way to go.

But nearly all cmake package scripts default to the dynamic libs...

Continuous integration builds have changed state:

Travis build 4225. State: passed. Details: https://travis-ci.org/widelands/widelands/builds/454944754.
Appveyor build 4021. State: success. Details: https://ci.appveyor.com/project/widelands-dev/widelands/build/_widelands_dev_widelands_update_appveyor-4021.

Ok, i'll merge this to trunk to get win builds up again.

I'll check the issue with glbinding the next days in a different branch...
