#!/usr/bin/env bash
# The single place msgpack-cxx headers are obtained. Sets MSGPACK_INCLUDE to
# shared/node_modules/msgpack-cxx-$MSGPACK_VER/include, downloading and
# unpacking the release tarball there if it isn't already present.
#
# Both a sourceable library and a standalone command:
#   source "$(dirname "${BASH_SOURCE[0]}")/msgpack-include.sh"  # then use "$MSGPACK_INCLUDE"
#   ./msgpack-include.sh                                        # ensure, then print the path
#
# yarn's postinstall (getMsgPack in shared/desktop/yarn-helper/index.mts) shells
# out to this, so a normal `yarn modules` leaves the headers in node_modules and
# every other caller hits the no-op path.
