Embedding is something that distributions avoid. Getting the full path
is possible if exposed somehow (like a CMake variable that holds the

Maybe, but there seems to be use cases:

https://sources.debian.org/src/plasma-workspace/4:5.19.5-5/wallpapers/image/wallpaper.knsrc.cmake/?hl=49#L49

just to name one.
