I’m using Plots (GR backend) to create some animations. At least on `osx`, Plots needs `cairo` and `ffmpeg` installed for animations to work. While I can “fix” that for the CI by adding this line to the `.travis.yml` file:

```julia
  - if [["$TRAVIS_OS_NAME" == "osx"]]; then brew install ffmpeg cairo; fi

```

it doesn’t take care of the fact that users that will use my package will have to manually install `cairo` and `ffmpeg`. Is there any other elegant way to solve this other than stating exactly that in the `README`?
