That would be great! My worry is not so much the (small) bit of extra 
engineering effort, it's that adding rpaths might have unintended 
consequences or cause more confusion among users than it resolves. This 
is merely based on the observation that I can't recall ever using a 
development toolchain that would set rpaths by default (apart from old 
libtooled projects, but it was done there only as part of the install 
step).

On another note, it's not just a question of setting 
CMAKE_INSTALL_PREFIX vs. not setting it. For example, setting any rpaths 
on -DCMAKE_INSTALL_PREFIX=/usr would be pretty unexpected, and from the 
looks of it would also break the Fedora packages.

I suppose one way to find out how to go about this would be to just add 
the rpath and see if anybody complains. How does DMD handle this?
