Error while compiling ofxFaceTracker example

After I installed and compiled OpenCV, I still have the same error, when I try to compile any of the examples of ofxFaceTracker.

I installed the latest version of OF

“fatal error: opencv/cv.h: No such file or directory”

The file is IO.h in ofxFaceTracker/<>/libs/include/

For anyone, who has a similar problem:

I tried to compile an example of ofxFaceTracker with 0.10.1

It does NOT work, so any info or solutions are very welcome…cheers!

I downgraded to OF 0.10.0 with OpenCV 3.2 installed…this seems the last constellation, that works for now.
I am ok with it…it is for a installation piece.
