Firmata installation in Qt

[Arum]

Hello everyone,
Actually i just start my project with Qt. I want to connect my Qt apps to arduino. So i have to install protocol library in Qt. I use firmata.
I have read installation guideline in https://github.com/callaa/qfirmata, but I bit confused. How can I install it properly? I am using windows 7 32bit.

Thank you in advanced for your help.

@Arum What exactly is the problem? Which compiler do you use (MinGW, VC++)?
Be aware that this library is for QML.
