I have always wondered why FindBoost doesn't add some speculative future 
Versions into _Boost_KNOWN_VERSIONS so that at least the Boost versions 
that are likely to appear during the lifecycle of the current CMake 
version are found without resorting to user supplied 
Boost_ADDITIONAL_VERSIONS. There is no harm in searching for versions 
that are never going to be released (except maybe longer search time), 
is there?

I was thinking of something along the lines of the attached patch.
Or is this a horrible idea?
