This is what you really need:

http://codepad.org/LVxUvSaF a probe
http://codepad.org/14TUDCor utilitary javascript functions that probe
references. Sorry for code quality ;)

This probe attaches to a HEAD file to make sure params are regenerated each
time it changes.
used in actual project as:

import "../../GitProbe.qbs" as GitProbe

.... later in product....

GitProbe {

    id: gitProbe

    sourceDirectory: project.sourceDirectory



    var result =base.concat([

                       "GIT_VERSION=" + "\"" + gitProbe.hash + "\"",

                       "GIT_TAG=" + "\"" + gitProbe.tag + "\"",

                       "GIT_COMMIT_DATE=" + "\"" + gitProbe.commitdate + "\"",


    return result


and then use these defines directly in code without any generated header.
