I don‘t have /usr/include/sys/videoio.h at all
Before that , I have ipp download question. So I download a ippiv from the internet and move it to the thirdparties.
Then the sys/videoio.h question came.
I mistake it is another question isolated from ippv. But it ‘s wrong.
After I disenable ippicv, it passed.
[opencv3.2cmake error ] sys/videoio.h no such file or directories
