Build shadowsocks-libev and its dependencies
Usage:
	$(basename $0) [--help|-h] [lib|bin|all]

	--help|-h	Show this usage.
	kcp		Build kcptun package (with its dependencies) only.
	lib		Build library packages only.
	bin		Build binary packages only.
			However, you need the libraries built previously, in current working directory.
			For advanced user only.
	all		Build both binary and library packages (default).
			The safe choice for everyone.

Please run this script in a clean place.
e.g.
	mkdir -p ~/build-area
	cd ~/build-area
	ln -s $(readlink -f $0) .
	./$(basename $0)
