How to build qzint.exe using:
- QT 5.7 installed in C:\qt\Qt5.7.1
  32 bit (use the offline installer and the 32 bit package)
- MS Visual Studio 2015 (VC12)

Build static Qt:
---------------
- Download: qt-opensource-windows-x86-msvc2015-5.7.1.exe
- Klick option "source" and deselect all other special modules.
- Install to C:\qt\5.7.1 (or another folder, then change the folders in the following)
- Install Python (ActivePython-2.7.13.2713-win64-x64-401787.exe)

- Start the VS2015 x86 native console by the start menu entry:
Visual Studio 2015\Visual Studio Tools\Windows Desktop Command Prompts\VS2015 x86 Native Tools-Eingabeaufforderung

- cd C:\Qt\5.7.1\5.7\Src
- set QMAKESPEC=win32-msvc2015
- configure.bat -static -release -prefix c:\qt\5.7.1static -qt-zlib -qt-pcre -qt-libpng -qt-libjpeg -qt-freetype -opengl desktop -qt-sql-sqlite -no-openssl -opensource -confirm-license -make libs -nomake tools -nomake examples -nomake tests -mp
  One may set another destination folder after the -prefix option.
  Attention, the upper command is one long line.
- nmake
- nmake install
  The last 3 commands run around 3 hours

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

Build libpng:
-------------
Open $ZH\..\lpng\projects\vstudio with VS2015 gui and convert the project
Set Project settings->C++->Code Generation->Library: Multi-Threadded DLL /MD
Copy the zlib source as required by the make file (in my case: zlib-1.2.8)
Build targets "Release Library" for zlib and libpng.

Build zint:
-----------
- Start in the start menu: "VS2015 x86 Native Tools-Eingabeaufforderung"
- set QTDIR=C:\Qt\5.7.1static
- set PATH=C:\Qt\5.7.1static\bin;%PATH%
- set QMAKESPEC=win32-msvc2015
- cd $ZH
- cd backend_qt
- qmake backend_qt.pro
- nmake clean
- nmake release
    
- cd ..\frontend_qt
- qmake frontend_qt.pro
- nmake clean
- nmake release
  -> qzint.exe is in the release folder
