[CMake] [CMake General][FindBoost] CMake and Boost 1.46.1

> try ... setting Boost_DEBUG On
Great suggestion!

I looked at the debug output as you recommended and discovered that
findboost only searches for filenames that start with "boost"  while
all the files in the lib directory start with "libboost"

I copied and renamed the regex files in the lib directory to start
with "boost" instead and it found the regex library but not the
others.  So a possible solution would be to rename all the files in
the folder.  This, however, is less than elegant.

Is this a breaking change in the way the boost library files are
named, a bug in findboost, or did I install boost wrong somehow?

Thanks
