The Boost-CMake (IMHO) sort of "abused" the cmake system somewhat in  
order to make it more "bjam" like.

In practice if the first pass of FindBoost.cmake does not find  
anything then I usually have to manually go into the CMakeCache.txt  
file and remove all the boost variables and re-run CMake. You can also  
probably do this using the CMake-Gui program.

Basically for each library, look in boost/libs/filesystem/ 
CMakeLists.txt. That file should get you started in the right location  
to start trying to figure out what is going wrong.
