This is no good.
As CMake advocate, I've noticed traces of disappointment accumulated
over the years. In CMake 2 times, that was a small pill to swallow.
In CMake 3.9, it's very frustrating.
Idioms, conventions, PEP kind of papers, whatever is a must.

Niall Douglas crafted a quick CMake'ification demo for Boost [1] and
from the short README one can learn more about **how** to properly
develop a good build setup with CMake than from the CMake documentation.
