That certainly works. The only problem I have with that is I have to do a

if(buildPlugin)
 use(Paraview)
else
 use(VTK)
endif()

in my root CMakeLists.txt. It would seem nicer to do

if(buildPlugin)
 add_subdirectory(Plugin)
endif()

and in the Plugin/CMakeLists.txt do

use(ParaView)

Is there a pattern more similar to this that would only use one of them?

Thanks,

David
