Great post ! Thank you for the write up.

Side note, you might be getting an error that looks like this:
CMake Error: The following variables are used in this project, but they are set to NOTFOUND.

It's because your cmake version is too old, the build system in the new hard fork requires a pretty up to date cmake version. See https://askubuntu.com/questions/829310/how-to-upgrade-cmake-in-ubuntu on how to update, or even better do your own research on how to update.
