I made it.
I opened the folder and it's compiled and it runs pretty well.

The tests have the following errors which are exclusively related with the test 
tooling, in my opinion.

```
Unable to open a connection to the X server.
DISPLAY=:1
Can't create OpenGL OffscreenView. Code: -1.

Error: openscad failed with return code 1

Test time =   0.06 sec
```

The tests compare the *image* of what it's supposed to render OpenSCAD with 
some already rendered images.
The problem is it's trying to access a screen and it's unable to do it.
There's `xvfb` for X testing but it's like it's not working.

Ideas?

Thanks!
