Then I would imagine the official site would have a downloadable binary already compiled. Github isn't really a place for getting compiled binaries, it's for collaboration and source control. I've never gone to a repository with the intent of being able to download compiled anything, chances are if you're apt enough getting to the repository you'd already know to expect this.

The author or vendor should be supplying a compiled binary for download in my opinion somewhere else like their website or even via Bittorrent.
