Unable to connect third-party file in the .h file

When you try to connect a third-party file in the .h file #include through, the compiler gives an error code Severity Description Project File status bar suppression
Error #include found after .generated.h file - the .generated.h file should always be the last #include in a header Survival. Can you please tell how to connect without error file?

What third party file exactly are you trying to include? If it’s some simple header-only library, or some internal C++ library, you should have high possibility of no errors. If it’s some serious external library with static and dynamic linked files, well, you are screwed (but you can solve it by using dll’s). You described your problem rather unclear, you need to give us some more details. I don’t even know if my answer will make any use for you.
