# meson automatically adds -rpath to targets and strips them when they
# are installed. ld adds a RUNPATH tag for -rpath arguments by default.
# This makes ld add a RPATH tag instead (as it did some time ago).
# The reason why we want RPATH and not RUNPATH is that LD_LIBRARY_PATH
# takes precedence over RUNPATH but not over RPATH. Since we usually run
# development builds in jhbuild which sets up LD_LIBRARY_PATH this can
# result in wrong dependencies being picked up by the linker.
