# Once done this will define:

#   VORBISFILE_INCLUDE_DIRS - the include directory/ies containing vorbis/ and ogg/
#   VORBISFILE_LIBRARIES    - the paths to the vorbis and vorbisfile libraries
#

# Find Ogg
find_package(Ogg QUIET)

# Find Vorbis
find_path(VORBIS_INCLUDE_DIR NAMES "vorbis/vorbisfile.h")
