build fails when a Cargo.toml exists in a directory above the project

🐛 Bug description

wasm-pack build fails with the following when a Cargo.toml exists in a directory above the current.

🤔 Expected Behavior

The webassembly and javascript should have been placed in out/static

👟 Steps to reproduce

To reproduce have two Cargo.toml files like this:

project/Cargo.toml
project/frontend/Cargo.toml

The frontend directory has the wasm target while the one above does not.

frontend/Cargo.toml contains the following lines:

[lib]
crate-type = ["cdylib", "rlib"]

from the frontend directory, run wasm-pack build

The error is this:

Error: crate-type must be cdylib to compile to wasm32-unknown-unknown. Add the following to your Cargo.toml file:

[lib]
crate-type = ["cdylib", "rlib"]
