cmake . challenge

[MightyMinds]

I would like to run BosonUSB on a Raspberry Pi Zero.

I can confirm, opencv is installed as well as v4l2.

However, when I run cmake . I get the following issue and I am just not knowledgeable enough to solve it.
CMake Error at CMakeLists.txt:4 (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.

-- Configuring incomplete, errors occurred!
See also "/home/pi/BosonUSB/CMakeFiles/CMakeOutput.log".
CMake Error: Unable to open check cache file for write. /home/pi/BosonUSB/CMakeFiles/cmake.check_cache

Please any guidance to solve the above, will be appreciated,
