With cmake 2.4 the binaries were relinked, with 2.6 the new RPATH is patched
into the existing executable.
Maybe this doesn't work on your system ?
Can you reproduce this with a testcase ?
set_target_properties(hello PROPERTIES INSTALL_RPATH /blub/ )
install(TARGETS hello DESTINATION bin)
and then check whether /blub made it into the installed executable.

With 2.6 cmake supports the variable CMAKE_PREFIX_PATH, which will be used in
the FIND_XXX() commands. I.e. for FIND_PROGRAM() /bin will be appended, for
FIND_LIBRARY() /lib and for FIND_PATH() /include accordingly.
Does that help ?
It is supported both as an environment var as well as a cmake variable.
