Yes, for instance for ossia score, the sequencer I'm working on which does some runtime compiling of c++ through clang & llvmjit, I ship a sdk for each platform with all the libc, libc++ headers. What a pain it was !

My scripts are the create-sdk-... Here if that can be useful to anyone: https://github.com/ossia/score/tree/master/ci and the SDKs are available at https://github.com/ossia/sdk
