Unity5 + vuforia4 Failed to encode to PNG

At the moment, Vuforia doesn't officially support Unity 5, so you may run into various errors and issues. We are in process of doing testing with it internally.

Unity5 + vuforia4 Failed to encode to PNG

A note about the issue reported (libpng issue):

it appears that this is caused by a conflict between the OpenCV framework and Unity5, and is not directly related to Vuforia.

Rebuilding OpenCV without libPNG fixes the issue.
