I read it, I just did not get it, being a newbie and all.    :-)
But, I see now.

I leave my existing makefiles in the source tree and CMake will
create the build Makefiles in the out-of-source area.
In this way they will not step on my existing makefiles.

Then, simple targets in the CMake makefiles can be used
to run the real targets in my existing makefile (which live
in the source area.)

Very clever.
