Looks like zlib is missing.

[mschlebusch]

Is it missing in any dependency of the sources or do I need to put it anywhere for the build process?

[mschlebusch]

I've found zlib in the following folder as 3rdparty dependency: ..\src\qt\3rdparty\zlib
Threfore it is generally available for the build process.

Due to our very limited maintenance capacity (see #14541 for more details), we need to prioritize our development focus on other tasks. Therefore, this issue will be automatically closed. In the future, if we see the need to attend to this issue again, then it will be reopened. Thank you for your contribution!
