Cannot build NVAPI CustomTiming.cpp sample: 7x error LNK2019: unresolved external symbol

I'm trying to compile the CustomTiming.cpp sample from the NVAPI SDK and I'm getting the following errors:

========== Build: 0 succeeded, 1 failed, 0 up-to-date, 0 skipped ==========

I have no idea where to find the missing external symbols, any gurus here to help?

I just found out on the following link that those functions are (unfortunately) part of the NDA version of NVAPI. How can I force any display resolution/timing I want?

EDIT Correction: Not true, they are included in the public release version, the sample code worked after I properly included the required dlls.
