that looks ok.

the problem seems to be that the build system does not link
against libOSGWindowGLUT.so. For this you have to change the
CMakeLists.txt file. Somewhere there should be something like
the following in there
target_link_libraries(MedievalTown
.
.
.
)
listing the libraries linked to the executable. Try to add
libOSGWindowGLUT.so to this list. There might be a difference
depending on the platform, e.g. something like IF(WIN32) so
you have to make sure it goes into the part active on unix
platforms.
kind regards
