If you test the CUDA sample in the original path you find all the things works well, but if you copy the project out may be there exist error 2019 and 2001 about the linker.
Here is the solution.
Copy the CUDA Sample folder to the location you want to put.
Because all the individual solutions are built under the Sample_20**.sln, if you only load one single solution VS cannot get the files which configured under the Sample_20**.sln solution.
Hope this could help you guys!
