Qt Creator 4.13.0 Build Failed if Qt is built as other namespace

my Qt is build in namespace DX and QtCreator 4.12.x works fine.

• following files should use QT_BEGIN_NAMESPACE and QT_END_NAMESPACE with UI class declareation

$\src\plugins\qmldesigner\assetexporterplugin\assetexportdialog.h
$\src\plugins\mesonprojectmanager\project\buildoptions\mesonbuildsettingswidget.h
$\src\plugins\mesonprojectmanager\project\buildoptions\mesonbuildstepconfigwidget.h
$\src\plugins\mesonprojectmanager\settings\general\generalsettingswidget.h
$\src\plugins\mesonprojectmanager\settings\tools\toolitemsettings.h
$\src\plugins\mesonprojectmanager\settings\tools\toolssettingswidget.h

like

QT_BEGIN_NAMESPACE
namespace Ui

QT_END_NAMESPACE

• follwing files are missing QT_BEGIN_NAMESPACE and QT_END_NAMESPACE for forward declaration

$\src\plugins\android\androidservicewidget.h
$\src\plugins\help\filtersettingspage.h

like

QT_BEGIN_NAMESPACE
class QHelpFilterSettingsWidget;
QT_END_NAMESPACE

• following file need  QT_BEGIN_NAMESPACE and QT_END_NAMESPACE to cover overload QDebug operator<<

$\src\plugins\qmldesigner\assetexporterplugin\assetexporterview.h
$\src\plugins\qmldesigner\assetexporterplugin\assetexporterview.cpp

like

QT_BEGIN_NAMESPACE
QDebug operator<<(QDebug os, const QmlDesigner::AssetExporterView::LoadState &s);
QT_END_NAMESPACE
