AFAIK we never pass OBJECT to add_library. It is detected by
dune_add_library which also contains a workaround to accomplish
something similar to object library. In this case it simply creates
global properties for the source files and linker flags for later
usage.

Definitely tested for 2.3.0 with cmake 2.8.6

I assume it was RHEL without anything.

Do you need more support with DUNE or HPC in general?
