libwebp/makefile.unix

# 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 'extras/libwebpextras.a'.
#
# To build the library and examples, use:
#    make -f makefile.unix
# from this top directory.
