Looks like the dnn module is shipped in OpenCV3 but current dependency is defined as >= 2.3.0. We could update the version to be > 3.0. Any idea why debian does not include the dnn module in the opencv package?

My archlinux install does have it as part of the standard opencv install.

Indeed, also Debian does not ship it. One can check here for existence
of this file in Debian/unstable:
    https://packages.debian.org/search?searchon=contents&keywords=dnn.hpp&mode=exactfilename&suite=unstable&arch=any

Umpf, that is not something I am going to do. It seems the dnn module is
not compiled for Debian or Ubuntu.

This is a pain.

Thanks for checking.
