Questions about c-api

[mihaly-sisak]

Hello all!
This is my first time touching Rust code and I feel a little bit lost.
I am more familiar with C so I wanted to give the c-api a try.
I found these tutorials: https://docs.wasmtime.dev/examples-c-gcd.html

However, I ran into an error. I did not have wasmtime_wat2wasm defined.
I stumbled upon WASMTIME_FEATURE_LIST.
I managed to fix this by adding wat = ["dep:wat", "wasmtime/wat"] to crates/c-api/Cargo.toml, adding "WAT", to crates/c-api/build.rs, and compiling with cargo build --release --package wasmtime-c-api --features wasmtime-c-api/wat.

What is the expected action if I want to enable/disable features? Do I need to modify build.rs, Cargo.toml and features.cmake to match? Or is it supposed to be matching automatically and I am just so new to cargo that I cant figure it out?
