Some windows dart clients report errors when running openCV dependent tests [1,2].
These tests crash due to missing dlls when run from a clean command line, after
\MITK-superbuild\ep\bin has been added to the PATH.
I tested it for two of those tests:
mitkCropOpenCVImageFilterTest additionally needs \MITK-superbuild\ep\src\OpenCV-build\bin\Release in the PATH.
mitkUSDeviceTest needs the above and \Qt\5.4\msvc2013_64_opengl\bin\ to work.
