I think we will need to use pkg-config, since it gives you all the dependencies of the ffmpeg libraries. For example, if you build ffmpeg from scratch out the box,...

So in short, though I don't claim to understand cmake at all, ```find_library``` and ```find_file``` are probs not the right idea since it won't tell you what the dependencies are.

@arrufat Is [opencv's cmake script](https://github.com/opencv/opencv/blob/master/modules/videoio/cmake/detect_ffmpeg.cmake) of any help?

@arrufat Do you mind taking ownership of the cmake stuff?

Well, you can take ownership of the whole thing if you really want to, I'm not bothered. But if i attempt to do the cmake stuff myself, i will probably...

Also, if all my verbose explanations are putting people off using this, then we need to stress that all dlib is doing is providing you with a wrapper. It's not...

Looking at cmake docs, it looks like ```CMAKE_PREFIX_PATH``` is added to the pkg-config search path. So maybe you won't need to set ```PKG_CONFIG_PATH```

Build fails because it can't find libavformat headers. That's normal. Will deal with that at some point in the distant future.

Probably. But I simply don't have spare time to work on this as none of my work projects justify it. I have my own implementations, they do the job and...
