[Bf-cycles] [Cycles]Compiling cuda binaries fails at run time

[Yansi Yao]

Hi all,
I check out cycles branch r4252, and build RelWithDebInfo version. There is no *.cubin files generated.
I read the svn log r41657 and find that cuda binaries will be generated at runtime.
Then I launch blender.exe and set cycles device to "GPU".
Then,in 3D View window, I set ViewportShading to Rendered, but nothing is rendered. 
The blender console window says:
`C:\Program` is not recognized as an internal or external command, operable program or batch file

I infer that Blender uses some CUDA environment variable which contains a whitsapce character.
Then I set environment variable %CUDA_BIN_PATH% from %CUDA_PATH%\bin to "%CUDA_PATH%\bin", and relaunch blender,
I find that it is "OpenCL GPU" instead "GPU" in Property->Render->Device. It means I can't use CUDA anymore. Very strange!
I load factory settings and delete all *.pyc in BlenderROOT\2.60\*, and relaunch blender, it is still "OpenCL GPU". 
I want to use Cycles with CUDA, but where is the "GPU" gone?

My environment is WIn7-x32, and some environment variables are:
CUDA_BIN_PATH=%CUDA_PATH%\bin
CUDA_INC_PATH=%CUDA_PATH%\include
CUDA_LIB_PATH=%CUDA_PATH%\lib\Win32
CUDA_PATH=%CUDA_PATH_V3_2%
CUDA_PATH_V3_2=C:\Program Files\NVIDIA GPU Computing Toolkit\CUDA\v3.2\
PATH=C:\Program Files\NVIDIA GPU Computing Toolkit\CUDA\v3.2\bin\;C:\Program Fil

Could you tell me how to solve this problem?
Thank you.
