Q Light Controller+

I have a windows laptop that I've been successfully compiling v4 on; having already worked through the workarounds for issues with the newer Qt (5.15.8 iirc). I tried switching to compiling qmlui (v5), and quickly ran into the error below. Is this a know issue by chance? If not, is there an appveyor file somewhere like this one that might give me a hint as to what I'm doing wrong?

Or, was I supposed to do a 'make clean' before my first v5 make? I tried just running 'qmake CONFIG+=qmlui FORCECONFIG=release' in the directory where I had just successfully compiled v4, and then ran 'make' and got the error below:
