Result Variables
^^^^^^^^^^^^^^^^

This will define the following variables:

``rubberband_FOUND``
  True if the system has the rubberband library.
``rubberband_INCLUDE_DIRS``
  Include directories needed to use rubberband.
``rubberband_LIBRARIES``
  Libraries needed to link to rubberband.
``rubberband_DEFINITIONS``
  Compile definitions needed to use rubberband.

Cache Variables
