Thanks for reporting these outputs; it's valuable to see what kind of outcomes users are experiencing on their own machines.

I can't think of any reason that installing libccd from source would cause any of the outputs that you're reporting.

The complaint about uuid-dev means we used the wrong key name for the libuuid dependency in the package.xml. I've created a PR to fix this so please pull that and try it out at your earliest convenience.

I think the complaint about nlohmann_json missing shouldn't happen if you have nlohmann_json_schema_validator_vendor in your colcon workspace and rosdep was run successfully for it. I suspect rosdep may have terminated prematurely because of the uuid-dev issue, so if you can try out the PR I linked and let me know if the issue persists, I would appreciate that.
