original command [SET(CMAKE_INSTALL_RPATH "${CMAKE_INSTALL_RPATH}:
$ORIGIN/../xxx")] not the ones with the hard coded -Wl,-rpath. From
your original email it appears you only tried various permutations
with the setting the linker path directly:

To get around the two problems above I tried setting the linker
flag variables directly:
SET (CMAKE_EXE_LINKER_FLAGS
"${CMAKE_EXE_LINKER_FLAGS} -Wl,-rpath,'$ORIGIN/../xxx/'" )

I'm glad you found a work around, but I hope someone from Kitware
would pipe in on how they think this should be done or if this is a bug.
It could be you need \\$ instead of $$ also.

part of the _value_ of the CMake *_LINKER_FLAGS variables
are treated using rules that aren't clear at all (at least
to me). On my system, a single $ is all that's needed for
shared library linker flags but $$ is required for exe
linker flags. But on another system the situation is the
opposite (shared libs get $$, exes get $).
For the time being, I'm using the macro below to paper over
the differences (on Linux, at least).

ENDMACRO ( APPEND_CMAKE_INSTALL_RPATH )
The macro takes a list of paths and can be used like this:
APPEND_CMAKE_INSTALL_RPATH(".;../../;/usr/local/lib")
