Adding external box2d Library to qt

[fatih1]

Hello, I wanted to add a physics simulation engine to qt. The external library is written in c++ and some people already implemented it but how can I include it to my project

UNfortunately, there is not much information about that

Thanks for your help

As can be seen on the github-repo you need to compile the library as described here: https://github.com/erincatto/box2d
After that you create your Qt project and add the libraries /include path to your project. Now you can implement your stuff using the classes from the lib and finally you need to link the lib in your qmake/CMake project file. So there isn't really any Qt involved here.

Just download and install CMake, then in Qt Creator settings make sure it detected the CMake installation and just open the project with Qt Creator
