I'm trying to build llvm on a system where zlib is not installed in the search path, to do this I'm using `-DLLVM_ENABLE_ZLIB=FORCE_ON -DZLIB_ROOT=my_path`. `libLLVM.so` builds but tools that link against `libLLVM.so` fail as they don't specify the path to zlib, e.g.
```

Full cmake command is (`[buildroot]` is just an abbreviation to keep the printed command shorter)

Am I doing something wrong or is this a bug, and if so any pointers on how to fix it.
