Global configuration file.

Do NOT use for settings local to some code or for settings that can change often.
Any change in this header will cause a rebuild of almost everything.

   -Werror,-Wreturn-std-move when it therefore considers a std::move to be missing.  On the other
   hand, at least some versions of GCC would emit -Werror=redundant-move in places where such a
   std::move would be added unconditionally, see c00948d9bd35dfb15a331c2163f32e9ee24644fd "Silence
