Can someone please guide me? Hello I am getting the following error while building

Did you include the pangolin headers and link with pangolin lib?

[zlingBryan]

@xdotzv I do not. How can i do it? Thank you!

Please search for simple errors yourself, github issues aren't there for fixing everyones dependency problems. Google pangolin headers and I suspect you can handle the rest yourself.
