#   macos-rpath-install-names.sh <libdir>
#
# Meson rewrites the install name of every installed shared library to its
# absolute install path (e.g. /opt/homebrew/lib/yams/libyams_onnx_resource.dylib)
# and points consumers at that path, so a staged or unzipped tree only runs from
# its final prefix. The executables already carry @executable_path/../lib/yams
# and the plugins @loader_path/.. RPATHs; restore the @rpath install name so
# those RPATHs are what resolves the library.
