This works fine here and I don't think it needs to be changed, cmake
handles the lib/lib64 thing internally. Most modules that come with it
don't have an explicit lib64 either.
Does it cause problems for you, can you give some more details?

thanks for the patch, I've applied the change to only do the library
setup once in r2480.

yes, osg2-config is not in very good shape unfortunately. The problem is
that some of the library dependencies are handled as imported library
targets and others just as regular libs. This makes writing the
information for osg2-config a bit tricky.
The osg2-config script is produced from three parts during a cmake run,
part 1 and 3 are in the CMake directory and part 2 is written from the
function OSG_STORE_PROJECT_DEPENDENCIES in CMake/BuildFunctions.cmake.
If you want to look into this it is probably a good idea to put
-DOSG_VERBOSE_BUILD_MESSAGES=ON on the cmake command line, this prints
information about the configuration of OpenSG libs.
Cheers,
Carsten
