When migrating to monorepo, we discussed a plan to provide slices for individual projects. While these haven't been provided officially,  we already have these for our own purposes (e.g. https://llvm.googlesource.com/llvm-project/libcxx/) and they are used by projects like Chromium. A potential solution would be extend the machinery so that the content of `<llvm-project>/cmake/Modules` is copied into each slice?
