I suggested a separate tarball <https://github.com/llvm/llvm-project/issues/53281#issuecomment-1052666213> for `cmake/`, but @kwk had the idea to pack it along with the existing projects (D118481 <https://reviews.llvm.org/D118481>) which would make it work transparently.

That is, if you have a pre-14 build script that unpacks the tarball, then switches into e.g. `llvm-$version.src/` and starts CMake there, it should also work with this, because the top-level CMake folder is in `../cmake`. Even if you add subprojects into e.g. `llvm/tools`, they should also find these files, because a copy comes with their own tarball.

If we nest this, existing build scripts will certainly have to be changed. Then I think we better just provide a separate copy.
