Where do I find these files?

[Aspirer]

I'm not sure what I'm supposed to do. I'm using VC++ 2010 express and CEGUI 0.7.7; I've already opened up the CEGUIBaseRenderer files and converted them. Now I need to build them but I keep running into the same errors:

I've done searches for zlib.h and ft2build.h and found nothing. I'm wondering why they aren't on my computer and whether I may have screwed something up in the lib and includes in the property pages.

BTW whats a dependency?
