-It is strongly recommended to use [vcpkg](https://github.com/Microsoft/vcpkg/) to install the dependencies on Windows. All modern IDEs support `vcpkg.json`. On the command-line, one can pass `CMAKE_TOOLCHAIN_FILE`=/path/to/vcpkg_root/scripts/buildsystems/vcpkg.cmake - see the [vcpkg documentation](https://github.com/microsoft/vcpkg).
-Users who wish to manage dependencies manually may need to populate `OpenCV_DIR` and potentially other `packagename_DIR` variables with the paths to their installations.
-On Linux (if not using an IDE that manages CMake configurations), you may also want to set `-DCMAKE_BUILD_TYPE=...` appropriately.
