It works better when using the system in the rigth way :) It works with

find_package(OROCOS-RTT REQUIRED rtt-marshalling rtt-scripting
${RTT_HINTS})
orocos_library(arp-core ${source_files} )
target_link_libraries( arp-core ${OROCOS-RTT_RTT-MARSHALLING_
LIBRARY} )
target_link_libraries( arp-core ${OROCOS-RTT_RTT-SCRIPTING_
LIBRARY} )

thanks all.

I was lurred by a commented line in the upper CMakeLists, it didn't solved

I tried to play with other Cmake commands as far as I may understand the
cmake documentation, but without success
