You have verified that the current autoconf/configure system won't work 
for *BSD.

That has nothing to do with CMake.
The main problem I have with CMake, is that I have to *intentionally 
break* the stock install before it will work: the instant you install 
the standard MingW32 sh at the same time as the other MingW32 tools, 
CMake is dead in the water.  The MSYS project type has a test that 
causes an immediate crash if it finds sh on the path.

While I didn't explain myself clearly on the CMake lists and bugtracker 
( http://public.kitware.com/Bug/view.php?id=7870 ), I got no hint that a 
patch to remediate the situation would be accepted.
