[CMake] Not finding boost

[Dave Yost]

Also, from what I can make of
   CMake.app/Contents/share/cmake-3.2/Modules/FindBoost.cmake
findBoost looks in
   /sw/local/
which is a path from the old, old Fink package system for OS X. findBoost should also look in
   /usr/local   (Homebrew and long unix tradition)
   /opt/local   (MacPorts)
   /opt/           (linux and others)
