Additionally, the install command needs to support the release flag.

@mb64 I can take a look at this. Adding here for tracking. This was observed when tracking down recent issues but this is not the cause of the issues.

After further investigation, it turns out that the release builds are working as expected. I have updated the issue accordingly. The only thing that needs to be fixed for this issue is the support for the release flag in the install command.

Another option would be to not support the --release flag but to rather build the release version by default. This would be more in line with how cargo install works.
