It's not implemented yet, but it should. Actually, more than "link if 
exists" i was thinking of a "link this, preferably ... if it's not 
there, here's a list of alternative names of this library and link 
whatever is available first off that list"

Well, demanding that to a developer consuming code or worst, to a final 
user ... for me, it feels like demanding arcanery or something

Well, I'll differ in considering autotools like a reference or standard 
when you implement a build system from scratch (which is the case of 
swift-build). At the end, it all boils down to repeating old and 
terrible designs, or making something cool (easy to set up, no forced 
fiddling to initially build and something pretty much distraction-less 
during development process ... I think a build system should aim for 
something like that, because we all benefit from something like that :D)

At my work, we're not married to any particular language and we have 
space to -judiciously- involve with new tech. Would love that to be the 
case with swift (I mainly write backend software with rust -which was a 
recent addition alongside the existing python codebase- and also code 
that does require it's share of C interop), but the whole build system 
story is the biggest deterrent at the moment (for now, swift is only 
used specifically for iOS development through xcode)

My two cents there,
