# Unlike libtool, vanilla Meson does not pass any information

# In common distributions, RPATH is only needed for internal libraries so
# meson removes everything else. With Nix, the locations of libraries
# are not as predictable, therefore we need to keep them in the RPATH.
# At the moment we are keeping the paths starting with /nix/store.
