# This script generates 'WebP.framework' (static library).
# An iOS app can decode WebP images by including 'WebP.framework'.
#
# 1. Download the latest libwebp source code from
# http://downloads.webmproject.org/releases/webp/index.html
# 2. Use this script instead of the original 'iosbuild.sh' to build the WebP.framework.
# It will build all modules, include mux, demux, coder and decoder.
#
# Notice: You should use Xcode 7 (or above) to support bitcode.
