Error on Qt 6 Building from source for Windows Based

My qt6vars.cmd:
REM Set up Microsoft Visual Studio 2019, where <arch> is amd64, x86, etc.
CALL "C:\Program Files (x86)\Microsoft Visual Studio\2019\Community\VC\Auxiliary\Build\vcvarsall.bat" amd64
SET _ROOT=C:\Qt\Qt-6
SET PATH=%_ROOT%\qtbase\bin;%_ROOT%\gnuwin32\bin;%PATH%

"C:\PROGRA~2\Microsoft Visual Studio\2019\COMMUN~1\VC\AUXILI~1\Build\vcvars64.bat" -o CMakeFiles\cmTC_ea43b.dir\CMakeCXXCompilerABI.cpp.obj -c "C:\Program Files\CMake\share\cmake-3.18\Modules\CMakeCXXCompilerABI.cpp"
This looks strange. This should be the call to the compiler, but instead vcvars64.bat is called. Can you show your script you created as described in the link (qt6vars.cmd)?

I'm not very familiar with Windows build environment, but is that OK?
I mean, it looks like the 64 bit version of cl.exe is being used, but it's strange that the Visual Studio installation went to the x86 folder, as a 32 bit application?Could you please describe your environment? i.e. Windows OS version and platform, same for Visual Studio.

Hi,
IIRC, cmake 3.19.2 or newer is recommended but I don't have the source at hand.

You should update your cmake version.

Did you restart from a clean state ?
