Usually when "could not find foo.lib" popping up without any mention of 
"foo.lib" on the link line points directly to these "autolinking" "features" 
being the culprit. It's just something I've learned through experience. If 
there's an FAQ of common problems when building C extensions, it belongs there.

While this functionality sounds nice in principle, it only really works if 
something also adds the directory to *look* for the library to the link line as 
well. But if you can get *that* to the link line, you may as well just add the 
".lib" to the link line directly and not send the linker on a wild goose chase 
based on a header. In addition, nothing ties "find python.lib" to the one that 
actually goes with the header that's telling it to be found either, so you can 
get the wrong one too (probably not so much an issue for Python now that ABI 
flags are gone, but it's still a thing).

Due to these behaviors and the lack of a link directory pragma (not that you 
could write a relocatable one in C preprocessor anyways), I find `#pragma 
comment(lib)` to just be a misfeature more than anything.
