Ok, just to halt this thread, I have a fix for the current pix_opencv build
situation with this script that I added
my pr <https://github.com/avilleret/pix_opencv/pull/11>

Afaic, pix_opencv actually tries to link as a single binary, but for some
reason, it just dont. I went ahead and made it so every object lives in its
own little bundle.

Thanks for your help!! Hope somebody finds this useful
