The ogre tools are not compiled. They don't compile correctly because cmake cannot correctly determine the xlibs to use while compiling. I suspect this is a problem with the N900 SDK. This could be fixed or at least worked around, but there is not much point because you can and should just install these natively on the PC. The 3D engine does compile but I have not yet tested it with the optional extra libraries freeimage and zzip so my build currently cannot load any texture or the ogre base example files. It does correctly initialize the render window though.
