FaceSubstitution build error (drawHighlightString was not declared)

[kaisark]

Update: Jan 14 4pm start
I added an image (jpg) of the Mona Lisa to the data/faces directory and the program runs now.

Update: Jan 14 4pm end

Update: Jan 14 start
Changed the drawHighlightString statements to generic prints. Compiled. However, I am getting a run-time error now. There must be some missing images in my set-up for the demo to run...???

-----------------------------------------
After successfully building CloningWrapper, I ran into the FaceSubstitution build error below. I wonder if this is a code version mismatch error between the various addons, etc??? FYI - I have built the example-blink app which runs successfully and which uses the following addons: ofxCv, ofxFaceTracker, ofxGui, ofxOpenCv, ofxOsc

I am using openFrameworks (stable) 0.9.8 on Ubuntu 16 (VM).
