SDL2.lua

	This file provides the project definition for the entire SDL2 library, on all
	platforms supported by the meta-build system. That includes Windows, MinGW,
	Cygwin, Mac OS X, iOS, and Linux. This project is responsible for setting up
	the source trees and the complicated dependencies required to build the
	final SDL2 library. In order to simplify this process, the library is split
	into several different segments. Each segment focuses on a different
	dependency and series of configurations which are thrown into the generated
	config header file, used to build this project.
