* Fri Aug 08 2025 Your Name <your.email@example.com> - 1.0-2.1
- Fixed invalid ctest command in spec file
```

### Explanation of Changes
1. **Line 75 Fix**: The invalid `ctest(:-:)` command was replaced with `ctest --output-on-failure`. This ensures that tests are executed correctly, and any failures will produce detailed output for debugging.
2. **No Other Changes**: The rest of the file remains unchanged, as no other issues were identified in the build log.

### Next Steps
After applying this fix, rebuild the package to verify that the issue is resolved. If additional errors arise, they can be addressed based on the new build logs.
