CMake: enable lib/edgepaint compilation

Note that the target here is named “edgepaintib” in anticipation of future
enabling of cmd/edgepaint claiming the name “edgepaint”. This also does not
define a separate liblab_gamut, as the Autotools build does. This separate
library seems only useful for cmd/edgepaint, so it does not seem worth splitting
it out as a separate library.

Gitlab: #1836
