This is an RTAI specific issue. Since RTAI 'userspace' headers require 
the patched Linux kernel headers, Orocos needs to know where your 
patched Linux tree is when building for LXRT. Just do as the error 
message says.

Once you build Orocos applications, the Linux header includes are no 
longer required.
