[CMake] Building a DLL and test driver EXE using CMake -- error by design?

That did it!!!! Thanks, Michael. That's exactly what I needed. 

It's somewhat moot now, but your second suggestion confused me, and I'd like to understand better:

> As an alternative, you might use a second invocation

> TARGET_LINK_LIBRARIES(FeatureViewer TARGET_LINK_LIBRARIES ...)

Two questions:
1. Does a second invocation override the first invocation?
2. If I remove the VTK libs from this command, wouldn't that leave FeatureViewer with unresolved symbols?

Thanks again for your help!!
