>Description:
If one is building libxfce4windowing in a non-sandboxed environment,
after the latest update of libdisplay-info (which bumped its SO major
from 2 to 3), this can result in build failures like:

ninja: build stopped: subcommand failed.

I don't follow (haven't analyzed) why when building itself
libxfce4windowing would be looking at previously installed versions
of its own library. Seems like something is amiss with the build
instructions generated by meson.

(I'm filing this as a record in case someone else hits this. I have
too many other things on my list at the moment, and this won't affect
binary package builds.)
