Subject: [PATCH] seperate out library compilation from general compilation

This can help with a more nuanced compilation. (eg. use system libraries
rather than compile our own)
Furthermore, it decreases the needed compilation time, since we needn't
recompile the whole thing when having cleaned out our local sources.
