Which library to install on target?

Hi,

I’m new to Qt Quick. So, This might sound like a dumb question. But I’m struggling with this.
I want to develop a complete UI for my embedded system using Qt Quick. So, I need QML to run my system.
Now, which library to install on my target embedded linux system.
I ‘ve seen this page : http://qt-project.org/downloads but it shows the library with 228MB! which will float my system size abnormally. I expect my system to be around 50MB only! I think this comes with lot of things which I dont want.
So, Can you please help me which to install? & how??

Thanks & Regards
