I was going to use this library in next version of https://github.com/agauniyal/rang for which I was going to use conan.io for package management. Thought instead of bundling or using git submodule, why not publish optional-lite on conan as well - https://bintray.com/agauniyal/rang/optional-lite%3Arang

Since its a header only library its not much of maintenance task so I'll be happy to maintain this. You can mention in readme if you want or if you have any objection to this upload please leave a comment :) The repo for conan recipie is - https://github.com/agauniyal/conan-optional-lite
