Visual Studio C++ "Function definition not found" on include

Question

I downloaded the detours source code and compiled it with nmake. Now I want to include it in a C++ project so I added the include directory path to the include directories as well as the #include "detours.h" on top of the C++ source file. The previously unresolved detours.h is now fixed however I still get Function definition not found errors in the detours.h file itself:

This causes a few linker errors like the following:

Error   LNK2019 unresolved external symbol _DetourTransactionBegin@0 referenced in function "unsigned long __stdcall InitializeHooks(void *)" (?InitializeHooks@@YGKPAX@Z)

The detours folder looks like this:

I already cleaned the solution and rebuilt it but the errors persist. Is there anything else I need to do to make it work? How do I tell Visual Studio where to look up the function definitions since specifying the includes doesn't seem to be enough?

Did you link with the library, where such function is defined in? Related: https://stackoverflow.com/questions/12573816/what-is-an-undefined-reference-unresolved-external-symbol-error-and-how-do-i-fix — Algirdas Preidžius, Jun 21 '18 at 14:39

I forgot to pass the .lib files to the linker as well:

Furthermore adding the libraries to the Library Directories path so the .lib files can be found at all.

Now the linker errors are gone.
