Now even I can figure out what that's supposed to mean, but the file I'm trying to include in my C program (#include <gtk.h>) IS in that directory.  Am I still doing something wrong here?

A line like

foo: bar gazonk

tells make that foo depends on bar and gazonk, nothing more. It tells
nothing about how bar and gazonk affects foo. I.e. this is not how one
adds extra object files when linking or additional include directories
when compiling. The "how" part is often stated on the lines below the
dependency line, but equally often (as in your case) it is from some
pattern rule, which may be implicit (as in your case).
