[GtkGLExt] how to install gtkglextmm in windows xp and vista?

[明覺 <shi minjue gmail com>]

I have developed a small app using gtkglextmm, and some users want to
test it in their windows(xp or vista) machine, so I'm trying to figure
out the steps to build my gtkglextmm app on windows. I have installed
MinGW, gtkmm successfully in windows, but I haven't found an installer
for gtkglextmm, anyone can help with it? thanks
