Linking Problems

I''m having problems knowing how do set up my include statements, here''s the problem: I have one source file called TileEngine.cpp it contains global variables and functions that are needed in the Tile Based game I am creating, I also have a Class called CSprite stored in CSprite.h and CSprite.cpp. I want this class to be used in TileEngine.cpp but there are globals in the TileEngine.cpp that I need to use in CSprite.h. So how do I set up my #include''s so I would get errors and it will all work out P.S. Is there are any good tutorials or articles on good ways of doing this kind of stuff???
