For reference, without the interface target it is as simple as:

 target_link_libraries(staticB $<LINK_ONLY:staticA>)

Do we have any enforcement for $<LINK_ONLY> to be used only with
static libraries?  Is there any reason not to allow it for all
library types?  It looks like a way to suppress usage requirements
specified by a package but that the consuming project does not
want for some reason.
