hmm, after fixing some small build issues (the gcc of Fedora 22 still
defaults to C++98 and was barfing on some C++11'isms) it seems the
example is working for me. At least I can see the colors adjust based on
the brightness of the image content - I'm running without the
AntTweakBar stuff, so only using initial settings for everything.
Can you perhaps send a screenshot of the problem or describe what is
going wrong?

The CallbackAlgorithmForeground is indeed a nice addition, thanks! What
exactly do you mean by "... provide CMake support for AntTweakBar", i.e.
what is missing to make it work or work better?
Cheers,
