|
|
# This module searches giflib and defines 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
