[Interest] Qt5 Installation

Sorry if this is a very silly question, but I run into a problem when cross
compiling and installing Qt5 (alpha and also recently released beta).

I configure Qt5 for cross compiling using --sysroot option, pointing to my
target's SDK folder. Like this: ./configure --sysroot /home/gsathyan/sdk
--prefix /opt/qt5 .....

The sdk folder contains a /usr/include and a /usr/lib folders with stuff
for my target device. I want to install Qt in a specific place, say
/opt/qt5 and I give this to --prefix option during configure.

But in /opt/qt5 only binaries (for host -- such as qmake, rcc, syncqt etc)
and mkspecs are installed. All target related stuff such as include, lib,
plugins etc are getting installed in a path which is a combo of my
--sysroot and --prefix values. It gets installed in

I tried using the plugindir libdir configure options, but still no luck. I
also tried exporting QTDIR before giving "make install" as referred to in
http://qt-project.org/wiki/Building_Qt_5_from_Git but still the same...
I want to install qt5 in its entirety in an absolute path I provide, and be
self-contained, ie not reference the installation path between various Qt

Please provide your suggestion.

Many thanks
