Re: Locating/Linking against Qt

[Brian]

I believe this to be the relevant code from [1]. I am unclear as to where 
$PKG_CONFIG comes from. It's not an environment variable and not set by 
configure. [2] is the AutoQt macro for Qt 1-3. 

dnl Check for AWT related Qt4
  if test "x${COMPILE_QT_PEER}" = xyes; then
    PKG_CHECK_MODULES(QT, QtGui >= 4.0.1)
    dnl Check needed because in some cases the QtGui includedir
    dnl doesn't contain the subsystem dir.

    QT_INCLUDE_DIR=$($PKG_CONFIG --variable=includedir QtGui)
    EXTRA_QT_INCLUDE_DIR="$QT_INCLUDE_DIR/Qt"
    AC_CHECK_FILE([$QT_INCLUDE_DIR/QWidget],
                  AC_MSG_NOTICE([No extra QT_INCLUDE_DIR needed]),

                  AC_CHECK_FILE([$EXTRA_QT_INCLUDE_DIR/QWidget],
                        QT_CFLAGS="$QT_CFLAGS -I$EXTRA_QT_INCLUDE_DIR",
                        AC_MSG_WARN([QWidget not found])))
    AC_MSG_NOTICE([Set QT_CFLAGS... $QT_CFLAGS])
    AC_CHECK_PROG(MOC, [moc], [moc])

    AC_SUBST(QT_CFLAGS)
    AC_SUBST(QT_LIBS)
  fi
