I get this error as well:

```
Error: The files llvm-project/build/lib/ocaml/llvm/llvm.cmi
       and llvm-project/build/lib/ocaml/llvm/llvm_debuginfo.cmi
       make inconsistent assumptions over interface Llvm
```

IIRC it's a bug in some CMakeFile. You need to explicitly run `ninja -Cbuild ocaml_llvm_debuginfo` again.
