See bug 4896 (http://www.cmake.org/Bug/bug.php?op=show&bugid=4896) for a
simple example of the issue of different behaviour for -D options depending
on whether the type is specified or not. Personally, I think the solution is
to assign a default type if none is specified with the -D command.  ON or OFF
gets BOOL everything else is STRING.
