Dear Sir,

i compiler an example DepthCamera success, but can't run, and error message is below

C:\working\DepthCapture\build\Release>depthcapture.exe -v 0451 -p 9105 -s 109793
21099619 -f testing.vxl -n 1 -t depth
WARNING: CameraSystem: No depth camera library found or loaded.
Detected devices:
No valid device found for the specified VID:PID:serialnumber

and i has set <path_to_voxel_sdk_folder>\build\bin and <path_to_voxel_sdk_folder>\build\lib

Does anyone encounter this problem?
