I just downloaded the source of ROS desktop full and I found that the opencv3 depended on libvtk-qt because in the package.xml of opencv3, I found <build_depend>libvtk-qt</build_depend> and <run_depend>libvtk-qt</run_depend>.

However, if I download the opencv3 from the official website of OpenCV, it doesn't depend on libvtk-qt.

Why does the opencv3 in ROS depend on libvtk-qt?
