I'm not doing anything too unusual for "installing" Qt. My recipes for
my Qt application simply inherit qt4e, and list qt4-embedded in
DEPENDS.

The only place where I deviated a bit from the norm is that I use a
qt4-embedded_4.8.3.bbappend to set up QT_CONFIG_FLAGS exactly as I
want them, and to rm ${D}/usr/bin/qtopia. Below's my bbappend. I'd be
interested to hear if there's a better way to clean out unneeded
directories from a rootfs (in my case ${D}/usr/bin/qtopia).

DEPENDS = "qt4-tools-native freetype jpeg libpng zlib"

# Override provided recipe and configure Qt4 to...
# - Disable irrelevant functionality and output
# - Disable SQL Plugins
# - Disable unused input/ouput
# - Have keyboard input and mouse input via /dev/input/mice
# - Have Linux framebuffer support
# - Use QML (so we need the declarative engine)
#
# Note, some of these might be extraneous, and this is a work in progress.
# (You've been warned!)

# Despite not building them, qt4.inc creates /usr/bin/qtopia/ with

    rm -rf ${D}/usr/bin/qtopia
