At Pocket Gamer Connects San Francisco 2015, Ricardo Quesada, Chief Architect at Chukong Technologies, gave a talk on using open source libraries in your games.

He started by identifying distinctions between the different licenses that libraries are covered by, from purely open source to "ad-hoc" licenses.

All the libraries under the sun

He recommended avoiding the latter variety, warning that "nobody tests them, and it's unclear if you can use them", which could lead to potential legal problems after release.

Quesada then went on to list the many libraries available that he suggests using, including Chukong's own Cocos2d-x engine.
