installing qt-everywhere-src-5.15.15 on windows

[danymt]

Could you explain to me how to install "qt-everywhere-src-5.15.15" using mingw on Windows from scratch?

[danymt]

I wanted to install qt 5.15.15 from the online installer, but it only allowed me to do it up to version 5.15.2, and I need a higher one

See https://doc.qt.io/qt-5/windows-building.html on how to compile Qt5.15 by yourself

When I perform the procedure described, I get the following error:

../../src/corelib/global/qglobal.h(45): fatal error C1083: Cannot open include file: 'type_traits': No such file or directory
NMAKE : fatal error U1077: '"C:\Program Files (x86)\Microsoft Visual Studio\2017\Enterprise\VC\Tools\MSVC\14.10.25017\bin\HostX86\x86\cl.EXE"' : return code '0x2'
Stop.

That error with 'type_traits' usually occurs when you have a mismatch between the compiler version (Visual Studio 17) and the Qt version you're building.
Lots of google hits on this, for example here
