Sorry for saying 'C' rather than 'C++'; didn't know that such sloppiness would 
I looked at the source (rather than trying to find things on mailing lists) 
because the documentation for cmake is much less mature than that for autoconf. 
 Yes there are rules files, but again documentation is less good/mature than 
that of the standard m4 macro language and shell scripts used by autoconf.  I'm 
not sayingm there's a big difference between the two systems, just that the age 
difference means that it's less hard to find solutions to maintain a project 
using the older one.
