# libxkbcommon-x11.so.0 without the unversioned development symlink.

# The real fix is installing libxkbcommon-x11-dev. When that package is absent
# this creates the one symlink the linker needs in a cache directory and exports
# LIBRARY_PATH, so a UI build works without root. Source it, do not run it.
