If no kernel packages are specified in options, G-API is using

thus G-API graphs are executed via OpenCV functions by default. OpenCV

Kernel packages may contain a mix of kernels, in particular, multiple
implementations of the same kernel. For example, a single kernel

"Filter2D". In this case, the implementation selection preference can
be specified with a special compilation parameter cv::gapi::lookup_order.
