I'm having a hard time building an executable from the example provided from https://github.com/microsoft/Azure-Kinect-Sensor-SDK/tree/develop/examples/green_screen
I've tried using cmake GUI, VS 2017's cmake but to no avail. I'm not even sure how I should be installing OpenCV. Can anyone please help me?
That is very odd behaviour. I would suggest verifying that all the steps in the Building and Dependencies page are followed as described. As you can see is not just OpenCV. Please go through the list and verify you have all the required software.
