Importing source to XCode

OK, I have a ton of C++ files that are all including each other (from a Windows project), but I need to find how to add directories for #include... there doesn't seem to be any intuitive place to look.

OK, ignore me for now.... We've figured out that if the files are added to a Framework they see each other fine. Now all we have to do is fix all the bits of code that gcc doesn't like...

I wish I knew a bit more about your project, I have not tried C++ yet

If my current experience is any indication C++ does not get along particularly well with OSX (or at least, not without some jimmying).
