+FindVorbis
+----------
+Finds the native vorbis, vorbisenc amd vorbisfile includes and libraries.
+Imported Targets
+^^^^^^^^^^^^^^^^
+This module provides the following imported targets, if found:
+``Vorbis::vorbis``
+  The Vorbis library
+``Vorbis::vorbisenc``
+  The VorbisEnc library
+``Vorbis::vorbisfile``
+  The VorbisFile library
+Result Variables
+^^^^^^^^^^^^^^^^
+This will define the following variables:
+``Vorbis_Vorbis_INCLUDE_DIRS``
+  List of include directories when using vorbis.
+``Vorbis_Enc_INCLUDE_DIRS``
+  List of include directories when using vorbisenc.
+``Vorbis_File_INCLUDE_DIRS``
+  List of include directories when using vorbisfile.
+``Vorbis_Vorbis_LIBRARIES``
+  List of libraries when using vorbis.
+``Vorbis_Enc_LIBRARIES``
+  List of libraries when using vorbisenc.
+``Vorbis_File_LIBRARIES``
+  List of libraries when using vorbisfile.
+``Vorbis_FOUND``
+  True if vorbis and requested components found.
+``Vorbis_Vorbis_FOUND``
+  True if vorbis found.
+``Vorbis_Enc_FOUND``
+  True if vorbisenc found.
+``Vorbis_Enc_FOUND``
+  True if vorbisfile found.
+Cache variables
+^^^^^^^^^^^^^^^
+The following cache variables may also be set:
+``Vorbis_Vorbis_INCLUDE_DIR``
+  The directory containing ``vorbis/vorbis.h``.
+``Vorbis_Enc_INCLUDE_DIR``
+  The directory containing ``vorbis/vorbisenc.h``.
+``Vorbis_File_INCLUDE_DIR``
+  The directory containing ``vorbis/vorbisenc.h``.
+``Vorbis_Vorbis_LIBRARY``
+  The path to the vorbis library.
+``Vorbis_Enc_LIBRARY``
+  The path to the vorbisenc library.
+``Vorbis_File_LIBRARY``
+  The path to the vorbisfile library.
+Hints
+^^^^^
+A user may set ``Vorbis_ROOT`` to a vorbis installation root to tell this module where to look.
