I should probably clarify this a little bit.  The cmpp compiler is an
executable which you get from Spice-OPUS.  I have modified the
Makefile.ams in the icm directory to call out for it when you make
the spice2poly target from the raw spice2poly.mod and spice2poly.ifs
files.  If you don't rebuild the entire directory from scratch (which
you probably don't want to do), then you don't need it. 

Perhaps the best way to understand how cmpp is used is to look at the
Makefiles in the icm and icm/icm_spice2poly dirs.
