Instead of EXECUTE_SCRIPT you  should have something like:
LDLIBS = `gtk-config --libs`
CFLAGS = `gtk-config --cflags`

and when compiling "model" use LDLIBS and in all the other CFLAGS.
"gtk-config --cflags" is the include directories needed to compile a gtk
app, and "gtk-config --libs" is the libraries needed to link the binary.
