Use -DCMAKE_BUILD_WITH_INSTALL_RPATH=1 to skip RPATH support for
the build tree and link directly with the final installation RPATH.
See my first response in this thread for details.

However, CMake's install-time RPATH update is a widely used feature
that is known to work in general.  (On non-ELF systems it even does
a preinstall step that re-links the binaries with the installation
tree RPATH.)  There must be something particular to the ARM platform
linker or the way it is being invoked that prevents the RPATH field
from appearing in the binary, but we'll have to wait for Mathias to
report back.
