Gtkglext how to make?

Can someone help me to compile gtkglext example.
I install Gtkglext under RH linux8 for default path.(Just configure & make & make install without any options).
The examples given there are alredy compiled using “make examples”. But I want to compile just a one example(eg: rotating-square.c ). So can any one help me to compile this or just send me an Makefile to compile this.
