command nmake very long building Qt5

[PublicNameName]

Im using Visual Studio 2022. First I tried to install Qt from extensions. Visual Studio 2022 offers Qt version 3.3.1.1, it can be downloaded from extensions. But such installation does not actually install Qt, it only creates a folder QtMsBuild. I don't know about others, but I had it like that. Then I decided to download Qt5 from the Internet using this link:
https://www.nic.funet.fi/pub/mirrors/download.qt-project.org/archive/qt/5.15/5.15.2/single/qt-everywhere-src-5.15.2.zip

After the download was complete, I unpacked it and found the qmake.exe file, which is required for Visual Studio to control versions, but it turned out to be non-working.

I found instructions on the Internet on how to fix this
https://www.qtcentre.org/threads/72011-Qt5-and-Visual-Studion-2022

And I did everything according to the instructions, but the building has been going on for 10 hours already! What should I do? Is this normal?

I need Qt for one project that I downloaded from GitНub, but that project does not have Qt5 files, so I had to install them separately.

@PublicNameName Why do you want to build Qt by yourself? Just use Qt Online Installer to install Qt for MSVC.
