Do we need to convert dispatch (and eventually workqueue) to using CMake to get the build system integration? Or do you want to leave libdispatch using autotools to drive its build and get swift-build to invoke a more or less unchanged autotools build for dispatch?

I don’t think using autotools is a barrier to integration into the larger build script. swift-corelibs-foundation actually builds with a pile of custom python right now. I think we want to preserve as much of dispatch’s current build system as possible. The swift/utils/build-script process is pretty flexible (since it’s a bunch of scripts itself).

Thanks,
