This is a fork of the Heroku Ruby buildpack, that includes OpenCV and CMake for gems like ruby-opencv and 'ropencv' and all the fun computer vision tools to work on Heroku.

Just set this as your buildpack with the following command:

heroku config:add BUILDPACK_URL=https://github.com/lilibethdlc/heroku-buildpack-ruby-opencv

Here's the basic flow of how the buildpack works:

• Installs CMake, unless already installed.
• Installs OpenCV, unless already installed.
• Continues with the heroku-buildpack-ruby flow
