It looks as thought you might be missing some escaped double-quotes. The
"/home/wec_devs/bkn.cn/caslvipre/rpa/deport/onejar_classpath.txt >>
/home/wec_devs/bkn.cn/caslvipre/U233_INTEL/onejar/boot-manifest.mf" is
one argument in your example. Try this:

INSTALL(CODE
  "EXECUTE_PROCESS (COMMAND cat
\"${CMAKE_CURRENT_SOURCE_DIR}/onejar_classpath.txt\" >>
\"${CMAKE_INSTALL_PREFIX}/onejar/boot-manifest.mf\")"
)


It's also worth noting that this is not a cross-platform command. Maybe
look at file(READ ...) followed by file(APPEND ...)?
