liberating clang - utils/TableGen/ClangOptionDocEmitter.cpp:176:8: error: no matching member function for call to 'Cases'

I am trying to liberate clang out of the LLVM directory tree as a stand alone build for my own language research and developemnt work.

I am sorry to dump all this here but I think both cases need looking into and I have not used LLVM and Clang for years.

I have attemped firstly to download the latest separate clang release https://github.com/llvm/llvm-project/releases/download/llvmorg-21.1.4/clang-21.1.4.src.tar.xz and build it, it produced multiple errors after fixing missing files/dependences from `llvm-project/cmake/Modules` :-
- GetDarwinLinkerVersion.cmake
- GetClangResourceDir.cmake
- GNUInstallPackageDir.cmake
- ExtendPath.cmake
- FindPrefixFromConfig.cmake

I am getting the following :-

```

Now I have tried copying the `llvm-project/clang` directory out separately. I still needed to copy the missing files/dependencies from `llvm-project/cmake/Modules` to `clang/cmake/modules`, as above.

I am now getting the following :-
