As another note: Since Qt 4.7 has pkgconfig support (and working well
from my Ubuntu 10.04 point of view), I have switched to using e.g.

PKG_CHECK_MODULES([QT], [QtCore QtGui Qt3D], [
])

along with small AC_PATH_PROGS([QT_MOC], ... checks for finding the
binaries.
This way the user just has to specify PKG_CONFIG_PATH (and
--with-Qt-bin) if Qt is hiding somewhere unusual.

This is not the most general solution (especially not for older Qt
version), but definitely convenient if latest features (in my case Qt3D)
is required anyway.


Kind regards,

Frederik
