- Workaround for wrong sprite in utility widget when selecting DrillStrike Note: It is better to extend utilityWidget to handle >=2 sprites/actions

# - Try to find the OggVorbis libraries
# Once done this will define
#
#  OGGVORBIS_FOUND       - system has both Ogg and Vorbis
#  OGGVORBIS_VERSION     - set either to 1 or 2
#  OGGVORBIS_INCLUDE_DIR - the OggVorbis include directory
#  OGGVORBIS_LIBRARIES   - the libraries needed to use OggVorbis
#
#  OGG_LIBRARY           - the Ogg library
#  OGG_INCLUDE_DIR       - the Ogg include directory
#  VORBIS_LIBRARY        - the Vorbis library
#  VORBIS_INCLUDE_DIR    - the Vorbis include directory
#  VORBISFILE_LIBRARY    - the VorbisFile library

### sommer [SuperTux]
##  - Removed unused vorbisenc library
##  - reversed order of libraries, so that cmake 2.4.5 for Windows generates an MSYS Makefile that will link correctly

### koda [Hedgewars]
##  - split ogg and vorbis lookup
##  - special case for framework handling
##  - standard variables handling
