It shouldn't be related to OpenCV, since OpenSlide doesn't use OpenCV and
vice versa.  But I'm not sure what's happening here.  Is there something
unusual about your libtiff installation?  Are there multiple copies of
libtiff on your system, one which is version 4.0.x and one which is older?

Please run these commands in the OpenSlide source tree and post the output:

    grep LIBTIFF Makefile
    make clean
    make V=1
