cd /usr/local/src/
unzip opencv-3.3.0.zip 
unzip opencv_contrib-master.zip
mkdir opencv-3.3.0/release/ -p
cd opencv-3.3.0/release
cmake -DCMAKE_BUILD_TYPE=Release -DCMAKE_INSTALL_PREFIX=/usr/local -DOPENCV_EXTRA_MODULES_PATH=../../opencv_contrib-master/modules ..
make

You should keep source code bases of opencv/opencv_contrib synchronized. Different versions are not tested for compatibility and may not work.

BTW, future usage questions should go to Users OpenCV Q/A forum: http://answers.opencv.org

After I received your email, I saw the difference of versions.

Before that, it was not clear that version 3.3.0 is not the master version.

Thank you.
