# using e.g. MacPorts gcc which don't have suppport for fat binaries
# built in.
#
# It ensures that both architectures are built, saving them under
# descriptive names and then 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.
