From Serge Lages, "Hi Robert,

You were right about the CMAKE_MODULE_LINKER_FLAGS option for CMake, so here is a modification allowing to not generate the manifest files for the plugins making them a lot more easy to redistribute. I have also made the same modification to the wrappers as they are also put into the osgPlugin folder when generated.
