Yes, most C++ compilers let you specify your language version. One of the problems with C++ is there is less of a dependency management story around it. - Maybe staticlibs will let you mix language versions? - Maybe DLLs will (granted you probably shouldn't have C++ in your ABI anyways)? - headers-only or vendored libraries won't allow mixing language versions. Contrast this with Rust where all of the standard approaches for declaring a dependency allow different language editions.
