[Interest] How to use a QML component from another subproject

[baneyue]

Hi all:
	
	I'm trying to use QML in my project, but i has some trouble using
	QtCreator.

	Here's the project structure:
	MyProject
		| MyProject.pro ----(TEMPLATE = subdirs)
		| MainWindow
			| MainWindow.pro
			| base_qml
				| base_qml.pri
				| QML
					| button.qml
					| *lineedit.qml*
				| Other files
					| qmldir
			| search_panel
				| search_panel.pri
				| ...
				| QML
					| *search_panel.qml*
					| ...
			| view_panel
			| Headers
			| ...
			| ...

	And in the `search_panel.pri`, i have:
		include(../base_qml/base_qml.pri)
	
	also in `MainWindow/base_qml/qmldir`:
		Button ./button.qml
		LineEdit ./line_edit.qml

	The trouble is that i want the _base_qml_ to manage all the basic
	elements(for example, a *lineedit.qml* that used both in search_panel
	and view_panel), BUT as the structure illustrated above, i CANNOT
	use the `LineEdit` element defined in lineedit.qml.

	Do I miss something?

	Thank you.
