# FindLibavif
# --------
#
# Find the avif headers and libraries.
#
# This module reports information about the avif
# installation in several variables.  General variables::
#
#   LIBAVIF_FOUND - true if the avif headers and libraries were found
#   LIBAVIF_INCLUDE_DIRS - the directory containing the avif headers
#   LIBAVIF_LIBRARIES - avif libraries to be linked
#
# The following cache variables may also be set::
#
#   LIBAVIF_INCLUDE_DIR - the directory containing the avif headers
#   LIBAVIF_LIBRARY - the avif library (if any)

# Find include directory

# TODO: use pkgconfig
