03f40955a3 img2webp: convert a sequence of images to an animated webp
Usage:

  img2webp [file-level options] [image files...] [per-frame options...]

File-level options (only used at the start of compression):
 -min_size ............ minimize size
 -loop <int> .......... loop count (default: 0, = infinite loop)
 -kmax <int> .......... maximum number of frame between key-frames
                        (0=only keyframes)
 -kmin <int> .......... minimum number of frame between key-frames
                        (0=disable key-frames altogether)
 -mixed ............... use mixed lossy/lossless automatic mode
 -v ................... verbose mode
 -h ................... this help

Per-frame options (only used for subsequent images input):
 -d <int> ............. frame duration in ms (default: 100)
 -lossless  ........... use lossless mode (default)
 -lossy ... ........... use lossy mode
 -q <float> ........... quality
 -m <int> ............. method to use

example: img2webp -loop 2 in0.png -lossy in1.jpg
                  -d 80 in2.tiff -o out.webp

ebee57f4d1 move imageio/example_util.[hc] (back to) examples/
decoding and file i/o have been split to imageio, all that remains is
some string routines used for parameter parsing in the examples

6c62841076 Split the main CMake file.
This will well isolate contributions for original code,
generated code and SIMD (especially for Android).

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.

696eb2b03a fix C and SIMD flags completion.
CMAKE_C_FLAGS is handled as a string and not a list by CMake.

3661b98069 Add a CMakeLists.txt
The goal is not to replace our autotools configuration, but to
provide a minimal CMake file that can build the lib, cwebp and
dwebp.
