cmake, main: work toward introducing alternative UI

We're going to base opentrack derivatives on the same branch. Previously

continuously-built executables will do a lot.

First opentrack variant in progress is a TrackHat device for mouse and
scrolling control for people with spine and hand/arm disabilities.
