using nvml in visual studio

I used NVML before to measure power consumption of a GPU K20c in LINUX.
Now i wanna do it in windows 10 and i have visual studio 2015.
At compile time, i get the error of linker:unresolved external symbol …(in nvml-related functions),
By searching a lot,it seems that i must link NVML library to VS and according to NVML API reference i added “C:\Program Files\NVIDIA Corporation\NVSMI” to the PATH environmental variable.
i still get this Error:unresolved external symbol …(in nvml-related functions)
Does anyone has any idea to solve this problem?
