Remove the use of requiring sudo for installing deps

[jkammerland]

Use a packagemanager or some other method

@jkammerland do you have a more specific recommendation? If you can post a PR we can discuss there

[jbeshay]

@jkammerland, You're probably using the ./build.sh script. The best way to avoid sudo right now is to use --no-install-dependencies and handle that manually outside of the script.

Alright thanks @jbeshay, I'm closing this in favor of #496. @lnicco Sounds good! But I will have to learn abit more here and see, I mentioned in #496 that I tried to use vcpkg for proxygen, was unsuccessful. I'm not suggesting to adopt vcpkg for the whole buildsystem, but just an idea.
