QT for aarch64

Hi, I am trying to compile Qt 4.8 for ARMv8. I need following packages.

libqt4-dev libqt4-opengl-dev libphonon-dev libicu-dev libsqlite3-dev libxext-dev libxrender-dev gperf libfontconfig1-dev libphonon-dev libpng12-dev libjpeg62-dev

I could not find these or any such packages on Linaro website. Is there any website which maintains packages compiled for ARMv8?

I downloaded Qt4.8 source code. But it seems I need to do many hacks to get it compiled for ARMv8. Is it already available some where?

Any help will be appreciated. Thanks Aparna
