well, it started to fail after I left only core stuff, so I looked at
exact  missing includes like this, on tablet:

grep video.hpp -r plugins/
 plugins/stylizeobj/stylizeobj.h:#include "opencv2/video/video.hpp"
 plugins/moveobj/moveobj.h:#include "opencv2/video/video.hpp"
 plugins/flowobj/flowobj.h:#include "opencv2/video/video.hpp"

and then I looked inside each include with mcedit and augmented my list
until it all was at least building again.

Problem is - dynamic build does not install opencv shared libraries (may be
due to danger of overwriting system components) so this mode does not work
out of the box ....

So, I left it alone for now.
