Build fails when target file makes use of the include_str macro for reading data

[johnsaigle]

cargo mutants appears to be unable to build and run a baseline when the unit test pulls in data from the filesystem via include_str!('../../some/path/to/test/data').

I imagine this happens because mutants is builds itself in its own directory and that messes up path resolution.

Any tips to address this?

Can you try building with --in-place?

Is the path an relative path pointing outside of the Cargo workspace tree?

Maybe if the baseline build fails then we should point to a doc with some debugging steps, including trying --in-place. A start on this is in https://github.com/sourcefrog/cargo-mutants/wiki/Troubleshooting.

Yes, and yes the baseline build did fail. I'll try with --in-place, thanks!
