Qt version 5.x can be used to compile SCCToolKit.

Changes

1. You can choose either Qt 4 or Qt 5 to build SCCToolKit in cmake.
2. However, if OpenCV was built with Qt, we must use this version of Qt. SCCToolKit automatically obtains where’s Qt used to build OpenCV.
3. Many bug fixes.

Important!

We recommend to use Qt 5.6 if you use Qt 5 from the following reasons,

1. Qt 5.6 was announced to be the long term support version (3 years +).
2. Qt 5.6 core license can be LGPLv2. ( Qt 5.7 uses LGLPv3, some modules without LGPL).
3. Qt 5.5 had glitch in layout that has been solved in 5.6.

The LTS of Qt 4 is 4.8. Unless under special circumstances, we recommend to use Qt 5. We will gradually removing updating for Qt 4.
