Running the Ripcord AppImage naively on a system with incompatible Qt5 libraries installed produces this error:

./Ripcord-0.4.26-x86_64.AppImage: symbol lookup error: /tmp/.mount_RipcorpHZPq2/plugins/bearer/libqconnmanbearer.so: undefined symbol: _ZdlPvm, version Qt_5

This happens because the Ripcord executable inside the AppImage uses the RUNPATH attribute instead of RPATH for specifying dynamic library lookup directory (./lib).

This causes conflicts if a system has a custom LD_LIBRARY_PATH set which points to system libraries, because RUNPATH has lower priority than LD_LIBRARY_PATH, and causing system Qt5 libs to be loaded instead of the ones bundled in the AppImage.

The solution would be to use RPATH instead as it takes precedence over LD_LIBRARY_PATH, or to use a wrapper script for AppRun which overrides LD_LIBRARY_PATH to point to ./libs

Thanks. I'll look into this. It may be because I'm using an older version of the AppImage creation tool.
