Please ship libclang.so

Rust bindgen tool relies on libclang shared library (configurable via CLANG_PATH + LIBCLANG_PATH).

A version can be installed from the ubuntu clang packages, but then there are 2 different versions of clang used for builds, which can be problematic.

WIP: enable rust for wasm/emscripten

Sounds like a reason able request. I guess we need to work about ABI compatibility, but that sounds like a pre-existing problem for any program linking against libclang?

Do you know how to enable and install libclang using CMake flags. The rules we use are here: https://chromium.googlesource.com/emscripten-releases/+/refs/heads/main/src/build.py#726

@dschuff

@dschuff how hard/costly would it be to start building/shipping libclang.so?

We are already shipping it in the non-release builds, since they are dylib builds. The release builds are statically linked and currently don't ship any dylibs.
I'd have to look; I imagine it wouldn't be too hard to do at least on Linux on Mac, but less sure about Windows. I guess we'd probably need to ship some headers too; IIRC we don't currently.
Regarding ABI compatibility, that's not something we can maintain across our releases currently, because we don't ship from release branches.
