<pre>
    I got this error while building a tool in clang:
```bash
llvm-project-main/clang/include/clang/Basic/ObjCRuntime.h:21:10: fatal error: llvm/Support/HashBuilder.h: No such file or directory
   21 | #include "llvm/Support/HashBuilder.h"
      |          ^~~~~~~~~~~~~~~~~~~~~~~~~~~~
compilation terminated.
```

how to fix it?
