Would have expected no dependency for the non-plugin-code, but even
the example from [1],[2] uses the QDesingerExportWidget include in the
non-plugin-code...
I would prefer some solution like:
diff --git a/analogclock.h b/analogclock.h
index b81a81e..1ac4b0f 100644
--- a/analogclock.h
+++ b/analogclock.h

#include <QWidget>
+#if defined(COMPILE_FOR_DESINGER_PLUGIN)

+#endif
to use QDesignerExportWidget/QDESIGNER_WIDGET_EXPORT only for the plugin compile...

No, you located the wrong file from build/qt5tools-5.9.1/include/QtUiPlugin/qdesignerexportwidget.h
the right one would be build/qt5tools-5.9.1/src/designer/src/uiplugin/qdesignerexportwidget.h
which is the one which would be installed from the build/qt5tools-5.9.1/src/designer/src/uiplugin/Makefile

Use the install_targ_headers target in build/qt5tools-5.9.1/src/designer/src/uiplugin/Makefile
but this will install some more (unneeded) headers...

This has nothing to do with the qtplugininfo executable, add an
extra config option in the Config.in file, e.g.:
config BR2_PACKAGE_QT5TOOLS_DESIGNER_HEADERS
boot "qtdesigner minimal headers"
help
Install the qtdesigner minimal header files for
the QtUiPlugin/QDesignerExportWidget include (does
not compile/install the complete designer).

Change to install qt5tools-5.9.1/include/QtUiPlugin/QDesignerExportWidget
and qt5tools-5.9.1/src/designer/src/uiplugin/qdesignerexportwidget.h
into the $(STAGING_DIR)/usr/include/qt5/QtUiPlugin directory...
