Hey Guys,

Latest SMTK Master is missing copying over some headers in their respective CMakeLists.txt.

smtk/attribute/Tag.h  
smtk/attribute/Definition.h  
smtk/operation/SpecificationOps.h  
smtk/common/Singleton.h

Thanks,

Corey

Whoops. The fix is incoming [here](https://gitlab.kitware.com/cmb/smtk/merge_requests/1230). Are you certain that `smtk/attribute/Definition.h` is not correctly installed?

I thought I was but looking at the current CMakeLists.txt I see it there.
