Very much inspired by ofxDlib. Using the generic_image.h interface, the conversions between dlib and Cinder are made toll-free, meanining no extra process is done and images are just interpreted into the target formats.
dlib needs to be built and placed in the lib folder. There are helper scripts in the install folder.
These are the threads I made or got involved with when working on this project:
