Errors on compiling OpenCV on MacOS Sierra

edit

Good evening guys,

I am having an error when I execute the command

make -j4

on my terminal. The error is the following:

/Users/lucadigiammarino/opencv/modules/videoio/src/cap_qtkit.mm:46:9: fatal error: 'QTKit/QTKit.h' file not found
#import <QTKit/QTKit.h>
        ^
1 error generated.
make[2]: *** [modules/videoio/CMakeFiles/opencv_videoio.dir/src/cap_qtkit.mm.o] Error 1
make[1]: *** [modules/videoio/CMakeFiles/opencv_videoio.dir/all] Error 2

I have been following this tutorial http://www.pyimagesearch.com/2015/06/... in order to get OpenCV 3.1.0 with Python on my Mac.

This is what I execute in order to configure the build:

cmake -D CMAKE_BUILD_TYPE=RELEASE \
    -D CMAKE_INSTALL_PREFIX=/usr/local \
    -D PYTHON3_PACKAGES_PATH=~/.virtualenvs/cv3/lib/python3.4/site-packages \
    -D PYTHON3_LIBRARY=/usr/local/Cellar/python3/3.4.3/Frameworks/Python.framework/Versions/3.4/lib/libpython3.4m.dylib \
    -D PYTHON3_INCLUDE_DIR=/usr/local/Cellar/python3/3.4.3/Frameworks/Python.framework/Versions/3.4/include/python3.4m \
    -D INSTALL_C_EXAMPLES=OFF \
    -D INSTALL_PYTHON_EXAMPLES=ON \
    -D BUILD_EXAMPLES=ON \
    -D BUILD_opencv_python3=ON \
    -D OPENCV_EXTRA_MODULES_PATH=~/opencv_contrib/modules ..

Thank you for your help.
