At the moment this "Drupal CMS Geo Images - Recipe" cannot be required via composer.
It looks that it is because it was wrongly created as "Module project", instead of generating it as a "General project" ...
That makes that Recipe not correctly requirable via composer, though all its code base is correct.
You will see that it requires: drupal/core ~8.0 without any code base reason.
