Install self compiled Qt3dstudio-runtime in own folder

After compilation of Qt3dStudio-runtime, I would like to install the binaries in an own folder.

With binaries, I mean, all executables, libraries and header files.

At the moment everything will be placed inside the Qt installation folder, when I execute: "make install"

I would like to configure this during qmake step.

The use case, why I need this. I want to create a self contained conan package for Qt3dStudio.

A self applied patch would be sufficient for the moment, as workaround.

My guess it is this function call in qt3dstudio.pro will lead to this behavior: "load(qt_parts)"

But I don't know how to fix it...
