> What have I done wrong?

One thing I apparently did wrong was not supply LLVM_ENABLE_PROJECTS so
I added that and CMAKE_INSTALL_PREFIX:

  $ cmake ../llvm -G Ninja -C ../clang/cmake/caches/DistributionExample.cmake -DLLVM_ENABLE_PROJECTS=clang -DCMAKE_INSTALL_PREFIX=/home/wink/local-dist

With there is now a stage2-distribution and it started compiling but eventually failed:

  ninja: build stopped: subcommand failed.G

So I'm guessing I need to "enable more projects" maybe addiong "compiler-rt;libclc;libcxxabi;libunwind", giving those a try now.
