[CMake] Eclipse/CMake projects show same file multiple times

[Campbell Barton]

With default Eclipse project (version 2.8.10.2), "Eclipse CDT4 - Unix
Makefiles", I get the same file showing multiple times when using
Open-Resources.

It also shows object files in the listing (.o) which is fairly
annoying and makes Open-Resources not that useful.

Example screenshot:

Is this a known problem?, Should I report a bug?
