[service] Abandoned or no‑longer‑maintained projects in Conan Center Index

[uilianries]

Summary

There are a number of recipes in Conan Center Index whose upstream projects appear to be abandoned or no longer maintained (no new releases, no commits for a long period, no responses to issues or pull requests). This can create problems for users who depend on these packages, especially when new compilers, platforms, or security requirements appear.

This issue is to list those Conan recipes that are packaging abandoned or non-maintained projects to discuss future actions.

I no longer work at Enjin so I can't say what the status of the SDK is anymore.
