This retains the desirable quality of not including paths to CUDA libraries from the build system into the config files, and has two major advantages: * It removes the need to use link_directories, which doesn't guarantee that the libraries from the supplied directory will be used (there may be libraries with the same names earlier in the search path). * It removes the need to put -L entries into OPENCV_LINKER_LIBS. This variable is used with target_link_libraries, where such entries are treated as linker flags, so doing this is unportable. I remove the support for -L entries from OpenCVGenPkgconfig.cmake, as well, to discourage adding them in the future.
