从dbus xml生成文件时如何告诉qmake包含头文件？

TLDR：如何告诉qmake使用dbus xml描述生成文件，其中包含适当的 Headers ？

下面是完整的示例和更多信息 .

我的描述dbus接口的xml文件（custom.xml）如下所示：

<?xml version="1.0" encoding="UTF-8" ?>

<!DOCTYPE node PUBLIC
  "-//freedesktop//DTD D-Bus Object Introspection 1.0//EN"
  "http://standards.freedesktop.org/dbus/1.0/introspect.dtd">

<node>
  <interface name="com.my.custom">

    <method name="Get">
      <arg type="a(sss)" name="info" direction="out"/>
      <annotation name="org.qtproject.QtDBus.QtTypeName.Out0" value="InfoArray"/>
    </method>

  </interface>
</node>

专业文件（ex.pro）如下所示：

TEMPLATE = lib

CONFIG += c++14 warn_on

QT += dbus

DBUS_INTERFACES += custom.xml

HEADERS += Info.hpp
SOURCES += Info.cpp

头文件（Info.hpp）：

#ifndef INFO_HPP
#define INFO_HPP


#include <QtDBus/QtDBus>
#include <QtCore/QString>
#include <QtCore/QList>
#include <QtCore/QMetaType>


class Info
{
public:

    friend const QDBusArgument &operator>>( const QDBusArgument &argument, Info& data );
    friend QDBusArgument &operator<<( QDBusArgument &argument, const Info& data );


    QString a;
    QString b;
    QString c;
};

typedef QList< Info > InfoArray;

Q_DECLARE_METATYPE(Info);
Q_DECLARE_METATYPE(InfoArray);

inline void registerCommType()
{
    qDBusRegisterMetaType<Info>();
    qDBusRegisterMetaType< InfoArray >();
}

#endif

和源文件（Info.cpp）：

#include "Info.hpp"

QDBusArgument& operator<<( QDBusArgument& argument,
                           const Info& data )
{
    argument.beginStructure();
        argument << data.a;
        argument << data.b;
        argument << data.c;
    argument.endStructure();

    return argument;
}

const QDBusArgument& operator>>( const QDBusArgument& argument,
                                 Info& data )
{
    argument.beginStructure();
        argument >> data.a;
        argument >> data.b;
        argument >> data.c;
    argument.endStructure();

    return argument;
}

当我尝试创建Makefile并构建库时，它会失败，因为生成的文件中的类型是未知的，因为生成的文件不包含 Info.hpp ：

What option do I use in the pro file, so the generated header file include Info.hpp?

我知道 qdbusxml2cpp 包含一个带有 -i 选项的 Headers . 如何告诉qmake这样做？
