cmake-gui: buggy when compiled by MSVC 14.33 / VS 17.3 toolset
After !7578 (merged) updated our CI to the MSVC 14.33 toolset (from VS 17.3), the cmake-gui
built by our nightly packaging pipeline (published here), no longer works reliably. Configuring randomly fails with various unrepeatable errors in processing the .cmake
language code. I've built several different versions of CMake in CI pipelines with MSVC 14.32 and 14.33 toolsets, and the distinction between the two MSVC versions is repeatable.
I suspect that the MSVC 14.33 toolset may be miscompiling Qt code in cmake-gui
in a way that clobbers memory elsewhere in the process.
