DllNotFoundException: ArucoUnity

I think I figured that out. I might upload some detailed example for people who might want to use but not familiar with cmake

I suggest use VS2015 instead of VS2017, there is some issue with cl.exe not found.

Part I, configure opencv contrib

1. Run Developer Command Prompt for VS2015.
2. Go to cmake.exe folder to run cmake-gui.exe.
3. Assign source and build folder with <opencv_dir>/source and <opencv_dir>/build and click configure.
4. Choose vs 2015 64bits as the generator. If this window did not show up, delete all caches and try again.
5. Find OPENCV_EXTRA_MODULES_PATH and add your <opencv-contrib-dir>/modules and click configure.
6. When you see all options turn white, click generate.
   Now you have solutions for opencv library. You can either build solutions through VS2015 or through other IDE.

Part II, generate ArucoUnity.dll
cd <aruco_unity_build_directory>
cmake -DCMAKE_INSTALL_PREFIX=<aruco_unity_install_directory> -DOpenCV_DIR=<opencv_install_directory> -G <generator-name> <aruco_unity_directory>
for example,
cmake -DCMAKE_INSTALL_PREFIX=aruco-unity\install -DOpenCV_DIR=opencv\build\install -G "Visual Studio 14 2015 Win64" aruco-unity\
cmake --build . --config Release --target INSTALL

Then you will have the ArucoUnity.dll in correct folder.
