Feel free to use `auto`, but you will need to hold off range based for
loops.

Please have a look at the nightly testers on
https://open.cdash.org/index.php?project=CMake and compare the feature
availability here: Please see

Currently CMake is still built with Visual Studio 2010, ie. MSVC 16.0.

That means we should be able to use auto, nullptr, lambdas, std::array,
std::function, type traits, trailing return types, r-values, ...
