Problem with building Qt 6.7.2 for Windows (msvc 2022) [shaders]

[nen777w]

I try to build Qt 6.7.2 from source on Windows with MSVC 2022 x64.
Configuration:

configure.bat -prefix %CD%\qtbase -opensource -debug-and-release -nomake examples -nomake tests -optimize-size -platform win32-msvc

then during the building, I get a lot of errors like:

[21/16998] Generating .qsb/scenegraph/shaders_ng/distancefieldoutlinetext_a_fwidth.frag.qsb
FAILED: qtdeclarative/src/quick/.qsb/scenegraph/shaders_ng/distancefieldoutlinetext_a_fwidth.frag.qsb U:/_tmp_/qt672mt2022/qtdeclarative/src/quick/.qsb/scenegraph/shaders_ng/distancefieldoutlinetext_a_fwidth.frag.qsb

Windows 32 bit isn’t a supported platform.
The shaders are probably just the first piece to fail for this reason.

@Axel-Spoerl please note that win32 is the name of the windows platform.

I was confused about this when I saw the win32-arm64-msvc. See https://code.qt.io/cgit/qt/qtbase.git/tree/mkspecs

It would be better if Qt would just use win or windows instead of win32, but it is how it is.

@cristian-adam Ouch, I’ve been there before. It always confuses me. Then perhaps the build tree is dirty and should be wiped.
We have no such errors on the windows platforms on CI.

I also got confused by some other post lately, where OP wants to build Qt5 x64 from source and used -platform -win32...
At first I thought is this wrong but apparently it's not :D
