Ticket #1112: build-osx-libs.2.sh

#!/bin/bash
#
# Script for acquiring and building OSX dependencies for 0 A.D.
#
# The script checks whether a source tarball exists for each
#  dependency, if not it will download the correct version from
#  the project's website, then it removes previous temp files,
#  extracts the tarball, configures and builds the lib. The script
#  should die on any errors to ease troubleshooting.
#
# make install is used to copy the compiled libs to each specific
#  directory and also the config tools (e.g. sdl-config). Because
#  of this, every developer must run this script at least once,
#  to configure the correct lib directories. It must be run again
#  if the libraries are moved.
#
# Building against an SDK is an option, though not required,
# as not all build environments contain the Developer SDKs.
# (Xcode does, but the Command Line Tools package does not)
#
