Can I run the code on windows? about gpu_flow

[audreyls]

Sorry for the old post, but for anyone else that has this problem, per this comment by @tneumann, I did the following:

1. Made a blank file "an_empty_file.cpp" in the \gpu_flow\ directory
2. Opened gpu_flow's CMakeLists.txt and, directly above the INCLUDE_DIRECTORIES(${OpenCV_INCLUDE_DIRS}) line, added in:

ADD_LIBRARY(opencv_dep_cudart STATIC <an_empty_file.cpp>)

and then added in "opencv_dep_cudart" to the TARGET_LINK_LIBRARIES sections underneath the ################################ like so:

TARGET_LINK_LIBRARIES(
  compute_flow
  ${OPENCV_LIBRARIES}
  ${OpenCV_LIBS}
  ${Qt5Widgets_LIBRARIES}
  opencv_dep_cudart
)

3. Then I made through CMake and built, and everything went fine after I added in dirent.h and a gettimeofday.h implementation to my Visual Studio include dir. The opencv_dep_cudart issue is an OpenCV bug, and doesn't have anything to do with Windows compatibility as far as I can tell. The file isn't actually used, so it can be assigned to an empty file to just satisfy the compiler.
