# - Try to find opusfile

# Once done this will define

# OPUSFILE_FOUND - system has opusfile
# OPUSFILE_INCLUDE_DIRS - the opusfile include directories
# OPUSFILE_LIBRARIES - Link these to use opusfile
# OPUSFILE_CFLAGS - Compile options to use opusfile
# opusfile::opusfile - Imported library of opusfile
#
# FIXME: opusfile does not ship an official opusfile cmake script,
# rename this file/variables/target when/if it has.
