Ember-simple-auth how to depend on it in an addon? - ember.js

Question

I am developing several webapps, and so, I decided to create an addon with all the ccs and bootstrap, moment and other addons to be reused.
One addon I want to use in my foundation addon is ember-simple-auth.
I declared it in as dependency, but is not included in the project when I run.
And so, in the browser I get an error of missing files.
According to #marcoow where, this sould be enough.

You can use the afterInstall hook in the default blueprint:
ember g blueprint name-of-your-addon
module.exports = {
normalizeEntityName: function() {},
afterInstall: function(options) {
return RSVP.all([
this.addPackageToProject('npm-package'),
this.addAddonToProject('ember-addon')
]);
}
};
I also struggled with this when developing an addon.
This article helped a lot (even though its somewhat outdated now), along with the official documentation.
