I don't think boost puts anything in the registry, so if it is not in 
the "usual" install location, CMake will not find it without setting 
BOOST_ROOT.  However, a "usual" install should just work.  I have 
checked in the fix to CVS CMake.  If you install it somewhere else, you 
will have to set BOOST_ROOT env or set it in the cmake-gui.
