#! /bin/sh
#
# This script is a part of Cgreen and creates fat versions of
# cgreen-runner and libcgreen.dylib which is necessary if you are
# using e.g. Homebrew/MacPorts gcc which don't have suppport for fat
# binaries built in.
#
# NOTE: This does not work completely automatic for x86_64/M1 since
# Homebrew GCC can only compile for the current architecture.
#
# Since automatically ensuring that both architectures are built is
# currently impossible from a single environment, you have to run this
# script once on each architecture. The script will save the built
# binaries under descriptive names and if it discovers that binaries
# for the other architecture already exists it uses lipo to merge them
# into fat binaries.
#
# At this point there is no way to run this as part of the CMake build
# and install, and since the install target of CMake always rebuilds
# you can't install them except with manual copying.
