If the nvidia libGL can be dynamically linked with, say, a vnc server, and
have it be a drop in replacement for the mesa libGL, then ldconfig_paths
would be fine.  If not, then those apps which need the mesa libGL would
need to link with -rpath perhaps to point at the "right" libGL (or
pass appropriate path info to those apps that might use dlopen(3)).
