                Compile OpenCV with TimVX
              
          
    Compiling OpenCV with TIM-VX backend

OpenCV with TIM-VX is developped to run deep learning models on NPUs (on Khadas VIM3 etc.) using OpenCV with TIM-VX integrated. Code is under review at opencv/opencv#21036. Inference performance on the NPU on Khadas VIM3 can be found in OpenCV Zoo: https://github.com/opencv/opencv_zoo#models--benchmark-results.
We provide two ways compiling OpenCV with TIM-VX backend:

(Recommanded) Compile OpenCV together with TIM-VX.
Compile OpenCV with TIM-VX library installed previously.
