  +## Generate doxygen documentation
  +
  +Requirements:
  +* Doxygen
  +* Graphviz
  +
  +In order to generate the doxygen documentation you must compile the sdk in the following way:
  +```console
  +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_1\local_path\websockets;C:\projects\aditof-sdk\opencv\build" -G "Visual Studio 16 2019" -DOPENSSL_INCLUDE_DIRS="C:\OpenSSL-Win64\include" -DWITH_DOC=on ..
  +cmake --build . --target doc -j 4
  +```
  +After compilation, the documentation could be found at this path:
  +```console
  +build\doc\doxygen_doc\html\index.html
  +```
