The structure looks very similar. The indi-dsi and indi-sbig actually were attempts, but failures, so you can ignore them. As I recall the only thing I had to do was the configure and make step in the gsl folder and then it worked from there. I don't think I had to build the others. But Adam reported that this worked fine on OS X El Capitan, but he had trouble on Sierra. Did you read the post he just sent about it?
One thing you could also try is the qt5 patch mentioned earlier (and also in Rob's instructions), because it excludes some modules that don't seem to be needed by kstars anyway (at least it worked decently for me). Using the patch decreases build time and probably also the disk space needed during the build significantly.
