Compile nDroid Repos to use?

[SuperXX]

Hi,

Does anyone know how to compile nDroid? I saw the XDA Developers tutorial (https://forum.xda-developers.com/t/port-calculator-android-on-the-ti-nspire-cx.3143757/), but all the download links are down, so the best thing I can do is compiling it. But, When I go to the nDroid github page: https://github.com/nDroidProject, it happears me a buch of repositories, but wasn´t it supposed to be like a huge single repository and then run "make" inside the Ndless folder like I would normally do with the great majority of other Ti-Nspire apps? Well, maybe it´s not that simple because of the "Boot.img.tns" and "System.tar.gz", but even with that, does anyone know how to compile this?

Thanks in advance
