# GIF_LIBRARIES - libraries to link to in order to use GIF
# GIF_FOUND, if false, do not try to link
# GIF_INCLUDE_DIR, where to find the headers
# GIF_VERSION, reports either version 4 or 3 (for everything before version 4)
#
# The minimum required version of giflib can be specified using the
# standard syntax, e.g. FIND_PACKAGE(GIF 4)
#
# $GIF_DIR is an environment variable that would
# correspond to the ./configure --prefix=$GIF_DIR

# Very basic version detection.
# The GIF_LIB_VERSION string in gif_lib.h seems to be unreliable, since it seems
# to be always " Version 2.0, " in versions 3.x of giflib.
# In version 4 the member UserData was added to GifFileType, so we check for this
