[CMake] RPATH/RUNPATH

[David Cole]

There is presently no explicit RUNPATH support in CMake. And no
immediate plans to add any support. In fact, your question is the
first time I've even noticed that RPATH and RUNPATH are two distinct
things...

Searching yielded these explanatory blog posts:
  http://fwarmerdam.blogspot.com/2010/12/rpath-runpath-and-ldlibrarypath.html
  http://www.physics.drexel.edu/~wking/unfolding-disasters/posts/rpath/

If you would like to encode a RUNPATH into a library or executable
that you are building with CMake, you can try adjusting the compiler
and linker flags as needed.

I take it you want to use RUNPATH so that there is still a path hint
encoded into the built products, but that you are then able to
override with LD_LIBRARY_PATH in a testing environment...?
