Old post, but hopefully this answer will save someone some time.

I was having the same problem with DEVPKEY properties - like DEVPKEY_Device_FriendlyName. I got a very similar link error. I stumbled upon the answer in comments here: Referencing GUIDs

Basically, add an #include before the include for things like devpkey.h where the property keys are defined.

So, at the top of my file I have:

#include   
#include   // Put this in to get rid of linker errors.  
#include   // Property keys defined here are now defined inline.
