KWsys is a completely configurable library designed to be used by other
projects without introducing dependencies they don't need.  Each class
that we use must be enabled.  In Insight/Utilities/CMakeLists.txt, there
is a line

  SET(KWSYS_USE_SystemTools 1)

to enable the SystemTools class.  You need only add

  SET(KWSYS_USE_Directory 1)

to enable the Directory class.  I've just noticed that I never wrote that
part in the documentation at the top of kwsys/CMakeLists.txt.  I'll add it
soon.
