Backscrub depends on tensorflow-lite sources, cmake does not help

I’m trying to build backscrub but I’m at an impasse.

The problem is that its source expects that the source for tensorflow-lite, including any CMake files, is in the git submodule and any try to build it fails.
And yes I’ve tried “cp -a${tensorflow-lite}/include tensorflow” and it fails as the sources do not include the appropriate CMakeFiles.
