Unable to build cjpeg as static library

[ostatnicky]

Can you give me an advice how to build cjpeg binary for macOS which would be static library?

I'm running everything like does https://github.com/imagemin/mozjpeg-bin/blob/master/lib/install.js
but final binary has only 47kb. I expect size around ~500kb.

My problem is that I'm missing libpng16.16.dylib when I'm running cjpeg.

./cjpeg test.jpg > result.jpg 
dyld: Library not loaded: /usr/local/opt/libpng/lib/libpng16.16.dylib
  Referenced from: /Users/xxx/test/./cjpeg
  Reason: image not found
Abort trap: 6

On macOS you'd need:

./configure libpng_LIBS='/usr/local/lib/libpng16.a -lz' --enable-static --disable-shared
make -j8

In case of link errors substitute /usr/local/lib/libpng16.a for whatever find /usr -name libpng*.a finds.

On other platforms you may need to replace -lz with a path to a static libz.a.
