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.

@jsulm
owww !!, that is the CXX variable i set in system environment. i should change it to vcvarsall.bat -

or what is the right compiler path ? this one ?: C:\Program Files (x86)\Microsoft Visual Studio\2019\Community\VC\Tools\MSVC\14.28.29333\bin\Hostx64\x64
@Lemat I think that path is correct. Visual Studio itself is a x86 application, but it has compiler which generates x86_64 binaries.

should i set a real compiler path in the system environment variable CXX ?? i don't know the real compiler file name. my actual Qt 5.15.2 has detected it automatically. i am looking in her settings to find the compiler file name, but nothing.
Time to elevate.

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