You could but, to avoid a maintenance headache, you'd normally end up 
getting the environment module to load any prereq environment modules, 
which would modify LD_LIBRARY_PATH.

In either case, it'd mean unexpectedly polluting the user's environment 
with things they didn't explicitly ask for, which I don't like doing.

Sorry - yes, I'm commenting it out and then specifying the 
CMAKE_INSTALL_RPATH I want on the command line.

Best,
