If the OOT requires C++11, then the setting you mention is the best way to go. If the OOT does not require C++11 or later, then not setting this variable is the way to go. Clang will auto-detect pretty reliably, but that makes for sloppy programming. I'd guess GCC6 or 7 does the same by now. It's m
