Summary:                    FindCUDA.cmake not able to link separate device code
because arch=-sm20 is not set. FIXIT!
Description: 
Build fails when SET(CUDA_SEPARABLE_COMPILATION ON) is set.
There is a "-arch=-sm20" missing in the correct cmake function where linking
happens. It is because set parameters get discarded (why?) and arch=-sm20 is not
default. NVCC throws an error then. 


Steps to Reproduce: 
Build with "SET(CUDA_SEPARABLE_COMPILATION ON)"

Additional Information: 
I wrote a small fix. The new FindCUDA.cmake is in the appendix. Use patch for
the line.
