[FR] Support `libclang.lib` on Windows

### Description

Hello, I'm using [opencv-rust](https://github.com/twistedfall/opencv-rust) which uses [clang-sys](https://[github.com/KyleMayes/clang-sys](https://github.com/KyleMayes/clang-sys)) to generate OpenCV bindings from Rust.

[clang-sys](https://[github.com/KyleMayes/clang-sys](https://github.com/KyleMayes/clang-sys)) requires me to provide `libclang.dll` and `libclang.lib` on Windows. I see #2046 and I use the packaged `libclang.dll`. But I can't find `libclang.lib` and I have to download another Clang to use it.

In this case, I wish I could also use the packaged `libclang.lib` to simplify my project configuration. So could you please provide `libclang.lib` on Windows, too?
