Cross-compile mxnet for raspberry pi with OPENCV and OPENMP

Hi MXNET Community

Need instructions to cross compile mxnet for raspberry pi using docker with opencv, openmp and DIST_KVSTORE enabled. I tried changing build_armv7() function to reflect my options but got the following error.

CMake Warning at CMakeLists.txt:376 (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 need help in figuring out what modification should be made as I have limited knowledge of docker.

Thanks
