Troubles installing N2D2 because of OpenCV not found

[alkaf-ahmed]

Hello,

While installing N2D2, I got the following message :

CMake Error at CMakeLists.txt:223 (find_package):
  By not providing "FindOpenCV.cmake" in CMAKE_MODULE_PATH this project has
  asked CMake to find a package configuration file provided by "OpenCV", but
  CMake did not find one.

  Could not find a package configuration file provided by "OpenCV" with any
  of the following names:

    OpenCVConfig.cmake
    opencv-config.cmake

  Add the installation prefix of "OpenCV" to CMAKE_PREFIX_PATH or set
  "OpenCV_DIR" to a directory containing one of the above files.  If "OpenCV"
  provides a separate development package or SDK, be sure it has been
  installed.

I can't find FindOpenCV.cmake anywhere in the repo, do I have to write it myself ?
I also can't find OpenCV_DIR to specifiy the location of OpenCV, any idea where can I find it ?

Thanks in advance for any help
