1> link: Fatal error lnk1181: cannot open input file 'xxx. OBJ'

I was almost killed by a very low-level problem recently and can easily describe it clearly, so it must be recorded.

I downloaded a demo from someone else a few days ago, and then configured the compilation to run normally under Debug. The release configuration was basically copied, And the Link error occurred during compilation.

1> link: Fatal error lnk1181: cannot open input file 'xxx. OBJ ',It took two days to discover the problem. The reason is very simple, that is, when you add (copy) dependent libraries, you may mistakenly put this XXX. lib suffix ". "lib" was lost, so I reported an error. I was so confused that I wanted to find a wall and hit it ......

I hope no one will make the same mistake !!!!!!
