Unable to find protoc installation for some architectures

Describe the problem

Even after running the this action, our project isn't able to find the protoc installation. Getting the error below

error: failed to run custom build command for `async-graphql-extension-apollo-tracing v3.2.14`

Caused by:

  Could not find `protoc` installation and this build crate cannot proceed without

      it, you can set the `PROTOC` environment variable with the specific path to your
      installed `protoc` binary.If you're on debian, try `apt-get install protobuf-compiler` or download it from https://github.com/protocolbuffers/protobuf/releases

If fails for the following targets

linux-x64-musl
linux-arm64-gnu
linux-arm64-musl
linux-ia32-gnu
win32-x64-msvc
win32-x64-gnu
win32-arm64-msvc
win32-ia32-gnu

To reproduce

Install protoc using this github action
Build https://github.com/tailcallhq/tailcall/tree/apollo-integration

Expected behavior

Build should succeed because protoc should be installed by the action but the build fails because it is unable to find the installation

'arduino/setup-protoc' version

v26.0-rc3

Additional context

No response

@shashitnak The problem seems to be that you're using a container to do cross-build for: linux-x64-musl, linux-arm64-gnu, linux-arm64-musl, linux-ia32-gnu, and win32-ia32-gnu. It seems that you have 2 problems:

Related to the missing protoc
For win build without cross-compilation, I see other errors not related to protoc.

Unfortunately, I can give you some hints only for the first point. When using GithubActions the setup-protoc (and similar actions) install the tool in the base os. If you're using an action that runs a container, all the tools you have installed in the base OS aren't available in the container. In your case, the cargo-action you're using for cross-compiling, under the hood uses the cross-rs which seems to perform the compilation in a container.

If you can mount the protoc binary in the cross-rs container you should solve the problem.
