I think my curiosity helped here :)

So I found out that there is different version of zlib in the Qt versions,
the working Qt has a version 1.2.11 (I can see it in the zlib.h in e.g.
C:\Qt\6.3.1\msvc2019_64\include\QtZlib folder and the broken Qt Versions
have 1.2.12 or 13.
I digged a bit more and found that our projects in Visual Studio include
those QtZlib folders for some reason:
and lyx's zlib folder gets included further below which means it has lower
priority. If I just remove the QtZlib include from the project, compilation
works. Can we do something in CMake here so that QtZlib is not included?
