Where are the OpenCV propId values located?

Question

These are the values that set different properties of the VideoCapture class. I have already included opencv2/opencv.hpp, but when I try to run

VideoCapture::set(CV_CAP_PROP_FPS, 20);

As seen in this documentation :

It gives me an error saying that CV_CAP_PROP_FPS is undefined. Where are the PropID values located?

I think you will need to include the opencv2/videoio/videoio_c.h file too. (It is unfortunate it was not mentioned in the docs.)
