  +### Enabling the point cloud display in aditof-demo
  +
  + OpenCV needs to be build manually in order to visualize pointCloud data because the prebuild libraries do not come with the viz module installed.
  + The steps required for building and including the required dependencies are presented below:
  +
  + Requirements:
  + * OpenCV 4.5.0
  + * VTK 8.2
  +
  +* VTK 8.2
  +```console
  +git clone --branch v8.2.0 --depth 1 https://github.com/Kitware/VTK.git
  +cd VTK
  +mkdir build_8_2_0 && cd build_8_2_0
  +cmake -DCMAKE_INSTALL_PREFIX=./local_path/vtk -G "Visual Studio 16 2019" ..
  +cmake --build . --target install --config Release
  +```
  +
  +* OpenCV
  +```console
  +git clone --branch 4.5.0 --depth 1 https://github.com/opencv/opencv.git
  +git clone --branch 4.5.0 --depth 1 https://github.com/opencv/opencv_contrib.git
  +cp -r .\opencv_contrib\modules\viz .\opencv\modules\
  +cd opencv
  +mkdir build_4_5_0 && cd build_4_5_0
  +cmake -DWITH_VTK=ON -DBUILD_opencv_viz=ON -DBUILD_opencv_world=ON -DCMAKE_PREFIX_PATH=./local_path/vtk -DCMAKE_INSTALL_PREFIX=./local_path/opencv -G "Visual Studio 16 2019" ..
  +cmake --build . --target install --config Release
  +```
  +Add the path from ./local_path/vtk/bin to enviroment variables to load them at runtine.
  +
  +Compile the sdk and add OpenCV to CMAKE_PREFIX_PATH:
  +
  +```console
  +cd aditof_sdk
  +mkdir build
  +cd build
  +cmake -DCMAKE_PREFIX_PATH="C:\projects\aditof-sdk\deps\glog\build_0_3_5\local_path\glog;C:\projects\aditof-sdk\deps\protobuf\build_3_9_0\local_path\protobuf;C:\projects\aditof-sdk\deps\libwebsockets\build_3_2_3\local_path\websockets;C:\projects\aditof-sdk\deps\opencv\build_4_5_0\local_path\opencv" -G "Visual Studio 16 2019" -DOPENSSL_INCLUDE_DIRS="C:\OpenSSL-Win64\include" -DWITH_EXAMPLES=on ..
  +cmake --build . --target install --config Release
  +```
