Answer 1

Additional to Frank's answer (which helped me very much, thanks for that!) I would like to add that this is only required vor MSVC, MinGW doesn't seem to need that line. Which was for me the most confusing part, I first thought I had problems with the msvc toolchain.

My inclusion now looks like this to reflect this fact:

msvc: LIBS += -luser32
