Old title: Building and installing Qt6 under Release is broken.
While running configure_qt_msvc.ps1 works correctly for the Debug profile, Release currently fails, and does so in a way that the script does not recognize as an error.
Turns out that CMake can't build Qt6 while the TimelineBuilder project is open in Visual Studio. The real issue is that the script doesn't communicate this to the user.
