The cmake command builds the Makefile correctly when I lower the required CMake version to 3.0, without errors.

It still does not build on Debian 8 but that is a different topic.

3.2 is required. With cmake 3.0 it would not build because of

$ make

Those errors are gone with CMake 3.2.

I could install cmake 3.6 on Debian 8 because it is in jessie-backports, see https://backports.debian.org/Instructions/
