Qt Creator compilation error (Qt 5)

Hello!

I am building Qt Creator 7 Beta 2 with Qt 5.15.2. The reason:
1. Prebuilt Qt Creator 7 using Qt 6 contains the small font issue on UHD monitors - https://bugreports.qt.io/browse/QTCREATORBUG-26643
2. Qt Creator 6 branch always leads to crash due to this annoying issue: https://bugreports.qt.io/browse/QTCREATORBUG-27044
As you can see the bug fix version is: Qt Creator 7.0.0-rc1 (7.0 branch).

So, I am trying to built Qt Creator 7 by myself using Visual Studio 2019/2022 from Git: https://github.com/qt-creator/qt-creator
I run the following commands:

cmake -DCMAKE_BUILD_TYPE=Release -G Ninja "-DCMAKE_PREFIX_PATH=C:\\Qt\\5.15.2\\msvc2019_64;C:\\LLVM" C:\\Users\\cobra\\Downloads\\qt-creator-opensource-src-7.0.0-beta2
cmake --build .

But it fails for me with this CmakeError.log error:

Determining if the include file pthread.h exists failed with the following output:

CheckIncludeFile.c(1): fatal error C1083: Cannot open include file: 'pthread.h': No such file or directory

Additionally, I have attached the cmake_output.txt file.
So, where should I find this file: pthread.h on Windows? Thank you.
