Not really, I think CMake initially sets the RUNPATH to the build tree,
as shown above, that’s OK.  I think it changes it upon “make install”.

One way to fix it would be to arrange to pass ‘-Wl,-rpath,'$ORIGIN'’ on
the link command line of the plugins.

Another solution would be to add a post-install phase to move
libmeshlab-common.so* to $output/lib, which seems more conventional,
though perhaps upstream had good reasons not to do that.

HTH!
