adding LibRaw-demosaic-pack-GPL3 support

Hi all! I came to know libraw searching for infos on since i'm impressed of RawTherapee results in automatic chromatic aberration correction.
It would be awesome for my workflow to be able to use a command line tool to convert raw to more suitable formats and removinc CA in the process.
I successfully downloaded and compiled libRaw (on win8/VS2012) but now i'm a little confused about how to add LibRaw-demosaic-pack-GPL3 goodies.

Any advice?
