Eventually the idea (discussed elsewhere in this thread) is to have
a BoostConfig.cmake that knows where everything is located. It should
also load this file, or at least set a variable indicating its location.
Then a user can do

  find_package(Boost 1.41 ...)
  include_directories(${Boost_INCLUDE_DIRS}) # or whatever variable
  add_executable(my_program main.cpp)
  target_link_libraries(my_program boost_thread-mt-shared-debug)

Ideally no user project should ever see the Boost.cmake exported-targets
file, or need to know where it is. It should all be loaded through the
find_package(Boost) command. That way BoostConfig can be re-organized
later without breaking projects.
