Shouldn't this be MTDEV2TUIO ?

The code of qtuio also suggests it requires GUI support in Qt, so I
guess some other dependencies are needed here.

This comment should be below the examples config option in order to
make sure that the examples config option gets "indented" under the
main qtuio config option.

Make this "qtuio examples".

Is mtdev2tuio really a build-time dependency? I don't think so. If it
isn't, then keep the select in the Config.in file, but remove the
build-time dependency here. Add a comment above the select in Config.in
that explicitly says that it is a runtime dependency only.

Mention the pong thing as a comment somewhere, only once, and don't
include the compile line if it isn't supported. Also, you could
simplify this as follows:

	for example in dials fingerpaint knobs pinchzoom ; do \
		(cd $(@D)/examples/$${examples} && $(QT_QMAKE)) ; \
	done

And indent the code with one tab.

> +endef

Indent with one tab.

Ditto: use a for loop + indent with one tab.

Normally, install -D requires the complete destination filename as
second argument. We usually use cp when multiple files need to be
copied at once.

Doesn't the qtuio package has a usable 'make install' ?
