Unable to build yew-router without cargo-web

[ffuugoo]

Basically, title.

I'm trying to build a simple web-app using yew (targeting wasm32-unknown-unknown). Right now I have a webpack-based build-system (more-or-less based on yew-wasm-pack-template).

Webpack wasm-pack-plugin, obviously, does not use cargo-web, but wasm-pack. And if I depend on yew-router in my Cargo.toml it fails during yew-router compilation with errors regarding js! macro.

I've fetched yew-router and tried to directy build it with cargo build --target wasm32-unknown-unknown and got the same errors. I've then installed cargo-web and successfully built it.

So, my questions is: Is it even possible to build yew-router without using cargo-web? Am I doing something wrong here?

Here is the error log:

Hm, thanks for the PR. I don't thought that it would build without cargo-web, but we may can find a way around it...
