Cannot find lnpps using CUDA 5.5

I just switched to CUDA 5.5 again and with the "latest" changes gpu/people did not compile anymore for me. Somehow the line 
  set(CUDA_npp_LIBRARY "${CUDA_nppc_LIBRARY};${CUDA_nppi_LIBRARY};${CUDA_npps_LIBRARY}" CACHE STRING "npp library")
does not really work (?). As I found out there are/were at least two others with the same problem, but it kept unfixed. So, here is my suggestion.
