libGL error: failed to load driver

[JintaoLee-Roger]

For example: "libGL error: MESA-LOADER: failed to open iris: /usr/lib/dri/iris_dri.so:" "libGL error: failed to load driver: iris"

This error is not caused by the CIGVis itself but is likely due to a version conflict with the shared libraries. More specifically, it may be caused by an unusual setting in the environment variable LD LIBRARY PATH (or DYLD LIBRARY PATH on macOS), which results in the incorrect shared library being loaded first.
