How to build qzint.exe using:
- QT 4
- MS Visual Studio 2008 (VC9)

Folder structure:
- zint source files in $ZH
  -> this file is in $ZH\frontend_qt4
- png1620.zip unzipped in $ZH\..\lpng
  -> $ZH\..\lpng\png.h exists
- zlib128.zip inzipped in folder $ZH\..\zlib
  -> $ZH\..\zlib\zlib.h exists

Prepare qt for static build

- Start "Visual Studio 2008 Command Line" (or execute "%VS90COMNTOOLS%vsvars32.bat" )
- cd c:\qt\4.8.6
- configure -static -release -qt-zlib  -qt-libpng -qt-libjpeg
- nmake
  -> took around 2 hours for me

Build pnglib and zlib
- cd $ZH\..\lpng\projects
- copy visual71 visual71_converted_to_9
- Start Visual Studio 2..8 (CV9)
- open Project: $ZH\..\lpng\projects\visualc71_converted_to_9\libpng.sln
- convert it as proposed by the IDE (no backup, we have made a copy before)
- select "LIB Release" configuration
- go to project "libpng" and open project options (ALT-F7)
- On the left, select "C/C++->Code generation"
- On the right change "Run time library" from "Multi-Treaded (/MT)" to "Multithread-DLL (/MD)"
- also do the upper steps for the project "zlib" (change /MT to /MD)
- Build libpng and zlib project using the Buildall menu entry
  -> this compiles png in the static lib:
   lpng\projects\visualc71_converted_to_9\Win32_LIB_Release\libpng.lib
   and zlib into the static lib
   lpng\projects\visualc71_converted_to_9\Win32_LIB_Release\zlib\zlib.lib

Build zint

- Start "Visual Studio 2008 Command Line" (or execute "%VS90COMNTOOLS%vsvars32.bat" )
- C:\Qt\4.8.6\bin\qtvars.bat
- cd $ZH
- cd backend_qt4
- qmake backend_qt4.pro
- nmake clean
- nmake release
    
- cd ..\frontend_qt4
- qmake frontend_qt4.pro
- nmake clean
- nmake release
  -> qzint.exe is in the release folder
