# shared objects; the outs they reference do. Put the GUI stack's real lib
# dirs on LD_LIBRARY_PATH — wayland, xkbcommon, EGL and vulkan are dlopened
# at runtime, so neither rpath nor a DT_NEEDED scan can cover them. Only
# matching package names are picked up: a blanket list would drag glibc and
# friends onto the path for every process in the shell.
