Unable to compile `envoy-proxy-dynamic-modules-rust-sdk` crate

[turmanticant]

What

Hey! I have a project using the rust bindings for envoys dynamic modules sdk that I am trying to bring into a monorepo. When I try to include it in my project it fails to compile.

Currently cargo successfully builds this crate. Bazel raises this error.

thread 'main' panicked at external/rules_rust++crate+crates__envoy-proxy-dynamic-modules-rust-sdk-0.1.0/build.rs:29:6:
Unable to generate bindings: NotExist("../../abi_version.h")

This crate generates bindings from cc sources outside of the crate root.

Reproduction Steps

Add dynamic modules to your Cargo.toml. I have also tried this with the starlark rules in my MODULE.bazel to the same effect.

envoy-proxy-dynamic-modules-rust-sdk = {	git = "https://github.com/envoyproxy/envoy",rev = "dc2d3098ae5641555f15c71d5bb5ce0060a8015c"}

Add the crate to a rust_binary. The code doesn't need to import anything from the crate, it just needs to be in the deps.

rust_binary(
    name = "hello_world",
    srcs = ["main.rs"],
    deps = ["@crates//:envoy-proxy-dynamic-modules-rust-sdk"],
)

Build the above target to trigger the error.

bazel build //:hello_world
# see 'full error' above for output
