#
# Script for acquiring and building OS X 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 build 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, OS X developers 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)
