Is it a good practice to force `RPATH` to be embedded in the installed targets?

For setting environment variables you should use the env-loader element of the roslaunch XML machine tag.

In this case, we only want to set the LD_LIBRARY_PATH of one specific node and must leave the other nodes on the same machine untouched. So I don’t think the env-loader element is a good fit.
