Basically, cmake check compiles do not respect C++11 which we set in parent so it is compiling tests with pre-C++11 and all of them failed because of that, not because of functions actually missing.
The reason why this was only found in Mac OS is probably because msvc/gcc default to a newer standard out of the box.
