* Fixed issue 11204: FindBoost.cmake had trouble discovering libraries
  when both -sgd and -gd libraries were available by adding a new option
  Boost_USE_STATIC_RUNTIME.
  Backwards compatibility of searching for first -gd and then -sgd on
  WIN32 is maintained unless the user sets Boost_COMPAT_STATIC_RUNTIME to
  false (or they have set Boost_USE_STATIC_RUNTIME).
* Fixed issue 8529: FindBoost was unable to detect boost libraries compiled against
  STLport, by reworking the way the Boost ABI tag is calculated.  There are additional
  ABI tag options available now as well.
* Boost_DEBUG now reports the full list of filenames being searched for when
  find_library is called.
