CMake upstream here. CMake 2.8.12 is *very* old, and it is likely that we will eventually remove support for < 2.8.12 altogether, resulting in errors (rather than just deprecation warnings) if you specify such an old version in cmake_minimum_required(). I would suggest updating the autopkgtests to request a newer CMake version. Kyle
