[Interest] Qt 6 and Windows with MSVC 2019

[Nuno Santos]

Hi,

I’m trying to experiment Qt 6 on Windows but I’m facing an issue.

If I setup a test quick project using qmake, it works. However, if I choose cmake failed to find the compiler with the following cmake error:

What could missing?

Thanks!
