compilation error in webkit-gtk

I am getting following error while compiling webkit-gtk for directfb, any guess how to resolve it?

The include path given to your compiler doesn't have gdk/gdk-directfb.h.

Either it's not installed and you need to install DirectFB or the makefile needs to be told where to look for it by adding a -I/path/to/directory/containing/gdk/gdk-directfb.h to the CC command.
