Hi!
Why do you require cmake >= 3.1 to build addons?
I think, you should stay compatible with at least Debian Jessie,
which ships cmake 3.0.2. This would also affect Raspbian.
I worked around this by changing the required cmake version
in several places of the source tree.

Because we need options only available in newer versions.

this is how i did mase76 workaround:
find ./ -name CMakeLists.txt|xargs -I {} sed -i 's/cmake_minimum_required(VERSION 3.1)/cmake_minimum_required(VERSION 3.0)/' {}
