Yes, you are correct. Thanks for the clarification.

Thanks for all of your explanations. It seems that introducing a way to do 
this with one command has some support.

So if SOME_FEATURE is true,

target_link_libraries(foo bar SOME_KEYWORD baz)
if (SOME_FEATURE)
  target_link_libraries(foo mar SOME_KEYWORD maz)
endif()

would have to result in bar and mar not being part of the link interface, 
and baz and maz being part of the link interface.

How do we decide on a keyword there? LINK_INTERFACE_DEPENDENCIES perhaps?

All the best,

Steve.
