# sudo apt-get -y autoremove    # Uncomment to remove packages that are now no longer needed


# 2. INSTALL THE DEPENDENCIES

# Build tools:
sudo apt-get install -y build-essential cmake

# GUI (if you want GTK, change 'qt5-default' to 'libgtkglext1-dev' and remove '-DWITH_QT=ON'):
sudo apt-get install -y qt5-default libvtk6-dev

# Media I/O:
sudo apt-get install -y zlib1g-dev libjpeg-dev libwebp-dev libpng-dev libtiff5-dev libjasper-dev \

# 3. INSTALL THE LIBRARY

wget https://github.com/opencv/opencv/archive/${OPENCV_VERSION}.zip
unzip ${OPENCV_VERSION}.zip && rm ${OPENCV_VERSION}.zip
mv opencv-${OPENCV_VERSION} OpenCV

if [ $OPENCV_CONTRIB = 'YES' ]; then

  mv opencv_contrib-${OPENCV_VERSION} opencv_contrib
  mv opencv_contrib OpenCV
fi

cd OpenCV && mkdir build && cd build

if [ $OPENCV_CONTRIB = 'NO' ]; then
cmake -DWITH_QT=ON -DWITH_OPENGL=ON -DFORCE_VTK=ON -DWITH_TBB=ON -DWITH_GDAL=ON \
