How to properly install the OpenCV package in Julia

How to properly install the OpenCv package in Julia.

I want to correctly install the OpenCV package in Julia, but when I install OpenCV, I get this error.

ERROR: The following package names could not be resolved:

  • OpenCV (not found in project, manifest or registry)
    Please specify by known name=uuid.

Can someone help me correct this error so that I can install the OpenCV package in Julia correctly?
