# Subject: [PATCH] meson: Setup darwin dylib versions
#
# autotools-builds of cairo had broken compat/current version management. They had current == compat
# and bumped every release, making them not suitable for distribution as system libraries.  In
# transitioning to meson, we're resetting this to a sane versioning scheme.
