Summary:                    CMAKE_SKIP_INSTALL_RPATH removes RPATH but leaves
empty RUNPATH.
Description: 
Hello,

I used the downloadable binary version of cmake for this test.

If I do not specify options for RPATH specific features, then the behaviour is
the same - this is probably the default anyway.

My first question is that if this behaviour (= empty RUNPATH) is intendend?

Since I assume not, both fields, RPATH and RUNPATH, should always have the same
contents or should both not exist at all. I could use
CMAKE_BUILD_WITH_INSTALL_RPATH or CMAKE_SKIP_BUILD_RPATH which works around the
problem, but then of course I would not be able to run programs from the build
directory.

Thank you for your answer,

Martin Lederhilger

Steps to Reproduce: 
Please see the test case in the attached tar.gz-file.
