Use the repo tool by google for your build system

[FFY00]

You should consider use the repo tool by google for your build system. We are cloning and building the same repositories over and over again because you don't use a shared folder for all of your dependencies. This results in big repository size, using a lot of unnecessary processing power, using a lot of unnecessary time and a messy cmake build.

Take a look a this project which is using repo: https://github.com/aurora-fw
Repo Tool: https://source.android.com/setup/using-repo

This was already discussed in #14.

Yes, there are multiple copies of repositories in /deps/ folders. But nothing should be built multiple times, incremental build should work. So what do you mean by?

building the same repositories over and over again
unnecessary processing power
messy cmake build

If there are some issues with this that we are not aware, please list them here and reopen this issue.
