Okay, but that is a clang configuration thing (`CLANG_DEFAULT_CXX_STDLIB` cmake
option), right? Can't you set it to the actual c++ library that you intend to
use instead of overriding it here? Or use a clang wrapper or a [configuration
file](https://clang.llvm.org/docs/UsersManual.html#configuration-files) to
override it externally? (FWIW, that's what we do internally to adapt the test
suite to our (strange) internal infrastructure)
It's nice (maybe) that `-lstdc++` is ignored on windows, but I still this this
is the wrong thing to do. `libstdc++` is definitely not the system default
everywhere.
