As the message says, you must say

  #include <ft2build.h>
  #include FT_FREETYPE_H

this is, you have to load ft2build.h (defining the macro
`FT_FREETYPE_H') before loading freetype.h itself, and you can't say

  #include freetype.h

at all.  This change has been announced years ago, and since some time
FreeType 2 enforces this loading scheme.

You might contact a gtk list how to solve the problem.
