Build instructions?
It'd be really useful to have some build instructions (esp. for different platforms) in the README.

e.g. there's a Makefile in the git repository, but it builds a .so file rather than a binary. `cmake && make` stomps over the Makefile but builds a binary.

Is there a makefile for building against SDL1.2 with my cross-compiler in `/opt/mipsel-linux-uclibc`? (I want to build an opk for retrofw).

Thanks!!
