Missing CUDA link directories

[mklingen]

When compiling using cuda-enabled OpenCV, I get the following:

/usr/bin/ld: cannot find -lcufft
/usr/bin/ld: cannot find -lnpps
/usr/bin/ld: cannot find -lnppi
/usr/bin/ld: cannot find -lnppc

I solved this on my own machine by adding this at line 18 to CMakeLists.txt:

  link_directories(/usr/local/cuda-7.0/lib64)

Ideally, the CMakeLists.txt file should deal with this automatically by detecting if CUDA is enabled and linking against it if it is.

I also encountered the same problem, but i do not know how to solve？
