As far as I know I got the whole wine. I followed the wine installation instructions at http://www.winehq.org/site/download-deb I've followed the instructions http://www.winehq.org/site/docs/winelib-guide/winelib-getting-started in how to port my project over. (there isn't much to it) I've read all of the documentation that can I find. And nothing mentions doing anything to point the Include variable, or where to point it to. Or what to do so windows.h and other system includes can be found.
