```
$ file Utilities/cmjsoncpp/CMakeFiles/cmjsoncpp.dir/src/lib_json/*.o
Utilities/cmjsoncpp/CMakeFiles/cmjsoncpp.dir/src/lib_json/json_reader.cpp.o: empty
Utilities/cmjsoncpp/CMakeFiles/cmjsoncpp.dir/src/lib_json/json_value.cpp.o:  empty
Utilities/cmjsoncpp/CMakeFiles/cmjsoncpp.dir/src/lib_json/json_writer.cpp.o: ELF 32-bit LSB relocatable, ARM, EABI5 version 1 (SYSV), not stripped
```

Somehow two of the .o files ended up empty.  The Makefile content
looks fine and the command line to compile is the same for all
three sources.  Is this reproducible?  If you remove the two empty
files and build again do they still end up empty?
