I am trying to do it on the (add_library foo ...) side, since that's the context that knows what symbols to link. Doing it on the (target_link_libraries) side requires that I mess around with a bunch of files every time my set of wrapped symbols needs to change---a process prone to error. I was expecting there to be an existing target property that I could use for the information, but that doesn't seem true.

As it is, I've written my own macro for linking with this particular library, essentially a custom target_link_libraries command: target_link_foo, that contains the right flags. This is basically unsatisfactory though, since I need to remember to use it and just hope everyone else does too.
