해결책 :

• Linker - Input - Additional Library Directories에 lib 폴더를 지정하고,
  Linker - Input - Additional Dependencies에  abc.lib 을 추가
  또는
  Linker - Input - Additional Library Directories에 lib 폴더를 지정하고,
  cpp 코드 상단에 #pragma comment(lib, "Ws2_32.lib") 를 추가
• 32 and 64 bit versions of the libraries을 맞춤 
  ( 32bit 프로젝트에 64bit lib을 넣어서 발생하는 경우도 있음) //16.8.11

  

cf.

Possible reasons:

• the sdl.lib and sdlmain.lib settings are not added to dependency list
• their location was not added to the list of directories where the linker looks
• you have mismatched 32 and 64 bit versions of the libraries.
