FindBoost.cmake in CMake 2.8.3 supports a new option to prevent searching
the system paths.  You should enable it if you are 100% sure that you will
never want to find something outside of BOOST_ROOT, CMAKE_PREFIX_PATH, etc.
Boost_NO_SYSTEM_PATHS

There was a bug related to not finding Boost libraries in a staging area.  I
believe this works now.

Also, take a moment and set this new variable appropriately (nearly all
users will want it to be OFF)
Boost_USE_STATIC_RUNTIME
