<![CDATA[x64 support]]>I have been using QT for displaying processed images on a windows PC in a real-time capture and display app. It is working well.

However I need to use CUDA to process images on a GPU which requires an x64 environment.

Hence I need QT to operate in an x64 environment under windows.

What are my options?

They support only Qt 5.6.2 at the moment (most likely due to the x86_64 webkit issues) but it works flawlessly.
