MSVC 2015 does not support C++14, so please remove this option. With Visual 
Studio you ALWAYS get __cplusplus defined to 199711L, so the configure test 
fails. That's even with MSVC 2017.

You also get NO C++14 features in Qt like the relaxed constepr, regardless of 
what Microsoft tells you. Please report an issue with them and ask them to 
support the SD-6 macros. I'm serious, please report it because they need the 
user pressure.

As for the other issues, it should be working. Can you attach the config.log 
that configure generated? It will tell what it tried to find and failed.
