# Usage:
#   find_package(VorbisFile [REQUIRED] [QUIET])
#
# Once done this will define:
#   VORBISFILE_FOUND        - system has Ogg and vorbisfile
#   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")

find_library(VORBIS_vorbis_LIBRARY NAMES "vorbis" "libvorbis_static")
