Automatic increment of build number in Qt Creator

Question

I would like to have a variable (or #define) in C++ source that will increment each time I use Qt Creator to build source code. Is there any way I can do this,

The Windows equivalent for Joerg Beutel's improved solution https://stackoverflow.com/a/5967447/1619432:

.pro:

build_nr.commands = build_inc.bat
build_nr.depends = FORCE
QMAKE_EXTRA_TARGETS += build_nr
PRE_TARGETDEPS += build_nr

HEADERS  += build.h

build_inc.bat:

@echo off 
set /p var= build.txt
echo #define BUILD %var% >build.h
echo %var%

Usage

#include "build.h"
...
qDebug() << "Build number:" << BUILD;
