I want to bring a .dll dependency into my Qt project.

So I added this to my .pro file:

win32 {
LIBS += C:\lib\dependency.lib
LIBS += C:\lib\dependency.dll
}

And then (I don't know if this is the right syntax or not)

#include <windows.h>
Q_DECL_IMPORT int WINAPI DoSomething();

btw the .dll looks something like this:

#include <windows.h>
BOOL APIENTRY DllMain(HANDLE hModule, DWORD ul_reason_for_call, 
                                        LPVOID lpReserved)
{
    return TRUE;
}

extern "C"
{
int WINAPI DoSomething() { return -1; }
};

Getting error: unresolved symbol?

Note: I'm not experienced with .dll's outside of .NET's ez pz assembly architechture, definitely a n00b.
