[CMake] Setting the object file directory.

[William A. Hoffman]

I think it would have to be more general than just SRC_TO_OBJ.
I suppose you could provide a translation table from src to obj dir.
However, what happens when you do an in-source build?  It sounds like
a lot of complication, and I am not quite sure I see the pay off.
