Hi guys,
It seems that frei0r-plugins will not use OpenCV as declared in the book:

CMake Warning:
Manually-specified variables were not used by the project:
OPENCV_DIR
It seems that OPENCV_DIR will not work if defined as OpenCV_DIR, leading
me to believe that the version that we have in the book right now is
incompatible. In addition, the OPENCV_DIR declaration that we have for
IPPICV in the same page won't work anymore either as the variable is
obsolete.
I propose the following:
- move OpenCV to Optional
- Remove the -DOPENCV_DIR= option in the CMake line (and the explanation)
Thank you,
- Doug
