CMake Proposal

[tridge at samba.org]

As I mentioned previously, I've been experimenting with using waf for
Samba builds. So far it looks very promising. 

For anyone that wants to try out what I've done, I've put up a short
wiki page here:

  http://wiki.samba.org/index.php/Waf

So far it builds libreplace, talloc, tevent, tdb and ldb. I'm working
on making it build the rest of Samba4 now.

You may also like to join the #waf channel on freenode, where the waf
developers are being very helpful.

Cheers, Tridge
