[INFO] [stderr] The bin target `detect-desktop-environment` in package `detect-desktop-environment v0.2.0 (/opt/rustwide/workdir)` has the same output filename as the lib target `detect_desktop_environment` in package `detect-desktop-environment v0.2.0 (/opt/rustwide/workdir)`.
[INFO] [stderr] Colliding filename is: /opt/rustwide/target/doc/detect_desktop_environment/index.html

[INFO] [stderr] the same path; see <https://github.com/rust-lang/cargo/issues/6313>.
