webp/makefile.unix
Pascal Massimino ae2a7222ce collect all decoding utilities from examples/ in libexampledec.a 
adds a generic examples/image_dec.[ch] entry point too.

WebPGuessImageType() can be used to infer image type.

# This makefile is a simpler alternative to the autoconf-based build
# system, for simple local building of the libraries and tools.
# It will not install the libraries system-wide, but just create the 'cwebp'
# and 'dwebp' tools in the examples/ directory, along with the static
# libraries 'src/libwebp.a', 'src/libwebpdecoder.a', 'src/mux/libwebpmux.a',
# 'src/demux/libwebpdemux.a' and 'src/libwebpextras.a'.
#
# To build the library and examples, use:
# make -f makefile.unix
# from this top directory.

# not, either follow the install instructions below or just comment out the next
