I oppened a bugtracker for this part, as I found that standard
gnulinux install has the same problem.


I successfully built log4cpp and rtt. But ocl has some difficulties to
find rtt. cmake says at the same time :
-- Found orocos-rtt 2.5.0 for the gnulinux target.
and
  but it set OROCOS-RTT_FOUND to FALSE so package "OROCOS-RTT" is considered
  to be NOT FOUND.

So I don't understand what's happening there. Can anyone helps with this ?


Here is the log :
