Trigger a rebuild if non-cargo-significant changes happened

[lu-zero]

In particular --prefix=/libdir/includedir changes and cbindgen.toml metadata.

I got bit by two rebuild issues: adding a cbindgen.toml didn't trigger a re-cbindgenning, and setting package.metadata.capi.library name didn't trigger a rebuild of the library, so install failed.

should be easy to add both in the hash computation, thank you for reporting.

This is still happening and very confusing as a user. I have a workflow that runs clippy, unit tests, and generates this header in one go. As-is, modifying cbindgen.toml does not trigger a rebuild.

As a workaround, I use this to make sure the header is built every time.

rm -fv target/$target/debug/cargo-c-geliad.cache
cargo cbuild

I'm using cargo-c 0.10.2+cargo-0.80.0

If you have a timeslice for it, it shouldn't be hard to add.
