Hi, @iamhankai

I met this error when cmake.

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!

What's wrong to me?

My machine: MacOSX Mojave, Libtorch, OpenCV installed.
