I'm having trouble building a project which uses include_str!
Double check if the source passed into the derivation is being cleaned or
filtered in anyway. Using craneLib.cleanCargoSource (or
craneLib.filterCargoSources directly) will omit any non-cargo and non-rust
files before trying to build the derivation. Thus if the project is trying to
use include_str!, include_bytes!, or any other attempt at accessing such a
file you may need to tweak the source filter to ensure the files are included.
Check out the source filtering section for more info!
Note that if the error is originating from a git-dependency, it may be a problem with the upstream source itself.
