UI: Fix UI file changes not being picked up by CMake

Due to how CMake and generated project files are structured, just using
AUTOUIC to pick up Qt `.ui` files will lead to a situation where
changing such a file doesn't trigger a regeneration of the associated
header files and thus a re-build of the target.

Upstream fix still requires `.ui` files to be added as target sources.
