opencv2 dependencies (?) about fastfusion HOT 1 OPEN

I think fatal error: opencv2/opencv.hpp has nothing to do with your openCV version. It just can't find the directory. Put this into your CMakeLists.txt include_directories("PATH_TO_OPEN_CV_Installation_Folder/include"). There you should find opencv.hpp

You can install different versions of opencv alongside, but I would recommend to do that in your home directory.

• Create an opencv-src-folder: clone into all your versions of opencv you want to use
• Create an opencv-install-folder:
• install opencv as normal, but change your CMAKE_INSTALL_PREFIX to your opencv-install-folder
• now create a link to switch between the different versions of opencv in your install-folder:
  ln -s Your_Open_CV_Version opencv_link. Now you can switch between the versions by changing the destination of opencv_link
• in CMakeLists set your CMAKE_PREFIX_PATH to your opencv_link set(CMAKE_PREFIX_PATH PathTo_opencv_link)
• If you use find_package(OpenCV YourVersion) in CMakeLists, you always have to change it to the version you want to compile with.

I wasn't able to compile fastfusion with opencv 3.3.1, but with 3.2.0 it worked.
