I do NOT want to uninstall my installed OpenCV and then install OpenCV for Movidius again...
[Caution] This is an unofficial procedure.
That's pretty easy.
Perhaps, commenting out all the scripts of "ncsdk/install-opencv.sh" and "ncsdk/uninstall-opencv.sh" will make it work.
I've been running opencv 4.0.0 with it for a while with no problems. What I did was:
1. Build and install opencv as you normally would
2. run the sdk installer (which will uninstall your opencv)
3. Rerun the opencv installer (should be quick since its already built) which should remove the sdk opencv
Although PINTOs solution is probably better.
