LLVM picking up the wrong libraries from the environment has cost me at least a couple of months over the last decade or so. Maybe twenty instances of customers being broken, ten hours or so in meetings explaining the problem and trying to persuade people that the right thing really is different for the system compiler vs your bespoke thing.

If you think it's better for your product to find unrelated libraries with the same name at runtime, you go for it.

Detecting that failure mode would be an interesting exercise - you could crawl your own address space after startup and try to guess whether the libraries you got are the ones you wanted. Probably implementable.
