CUDA VS2010 settings' error lib path error

Hi All
In my box I have a lib path environment setting:
CUDA_LIB_PATH=C:\Program Files\NVIDIA GPU Computing Toolkit\CUDA\v3.2\lib\WIN32

IN THAT FOLDER IT HAS CUDA.LIB IN IT.

IN PROPERTIES OF THE PROJECT, I SET THE ADDITIONAL LIBRARY DIRECTORIES AS BELOW:

LINKER->ADDITIONAL LIBRARY DIRECTORIES=$(CUDA_LIB_PATH)

I ASSUME IT WILL BE SUBSTITUTED BY “C:\Program Files\NVIDIA GPU Computing Toolkit\CUDA\v3.2\lib\WIN32”

BUT WHEN I COMPILE IT, IT COMPLAINS THAT CANNOT FIND CUDA.LIB. (SAME SETTING IN VS2008 WORKS AS I RECALL)

THEN I FIND THAT COMMANDLINE HAS THIS

/LIBPATH:“C:\Program Files\NVIDIA GPU Computing Toolkit\CUDA\v3.2\lib\WIN32…\LIB”

THE IDE ADDED THIS “…\LIB” AT THE END OF THE PATH BY ITSELF. WHY IT DOES IT?

I WAS FORCED TO CHANGE THEM AS BELOW TO MAKE IT WORKS:

CUDA_LIB_PATH=C:\Program Files\NVIDIA GPU Computing Toolkit\CUDA\v3.2\lib
LINKER->ADDITIONAL LIBRARY DIRECTORIES=$(CUDA_LIB_PATH)\WIN32

THANKS IN ADVANCE
