OCL Linking with XENOMAI

The Cmake compilation rules of the OCL do not add the link to the xenomai libs. A wor arround is to set CMAKE_MODULE_LINKER_FLAGS at -lxenomai with cmake ..

I had hit this problem too. It appears that when using the Xenomai 2.5 Debian
package, both libnative and libxenomai are required, while RTT/OCL assume only
libnative is necessary (as was before). I think I adapted the
FindXenomai.cmake macro to fix this.

We'll have to put all these fixes in a RTT 1.10.4 and OCL 1.10.3

I think I have the same problem. Here is the error I get when execute >make
