DEV-26150 (VWR-11474): CMake 2.6.2 adds multiple `-lndofdev' when linking

secondlife-bin on Linux.

CMake will insert multiple -lndofdev parameters into the Makefile that
links secondlife-bin IFF ${NDOF_LIBRARY} is listed *after* Xinerama in
the target_link_libraries() call in indra/newview/CMakeLists.txt file.
Moving the reference to NDOF_LIBRARY above viewer_LIBRARIES seems to fix
it, and doesn't break Windows or MacOS.

Not reviewed.
