1. Among 3rd-party in openCV, there is ippicv which is not open source sw.  
When AGPL 3.0 Project uses openCV, can this project use ippicv without any conflict?  
Or should I disclose the source code of ippicv?
2. If I cannot use ippicv because of AGPL License, is any version of openCV without ippicv?  
I do not want to rebuild openCV.

I know license of openCV.  
I wonder about AGPL Project links openCV project.  
It is different case.
