I'm new to the Qt designer and I need to make a project which includes a speedometer, luckily I was able to find a plugin on the internet for a speedometer but the problem is I don't know how to install it to the Qt designer and to be added to my widget. I tried to search on the internet and all I found is how to install plugins in Qt creator. Please note that I use the combination of Qt designer, Cmake and visual studio 2010 (not Qt visual studio Addin) to build my project.
Here is the link for the plugin I want to install: https://github.com/efesler/Qt-Speedometer-Widget
