warning: output filename collision.
The lib target `objr` in package `objr v0.1.0 (https://github.com/drewcrawford/objr#84d444b4)` has the same output filename as the lib target `objr` in package `objr v0.1.0 (/Users/drew/Code/rustc-84738/objr)`.
Colliding filename is: /Users/drew/Code/rustc-84738/corevideor/target/doc/objr/index.html
The targets should have unique names.
This is a known bug where multiple crates with the same name use
the same path; see <https://github.com/rust-lang/cargo/issues/6313>.
