dnl @synopsis BNV_HAVE_QT [--with-Qt-includes=DIR] [--with-Qt-dir=DIR]
dnl
dnl Search for Trolltech's Qt GUI framework.
dnl
dnl Searches common directories for Qt include files, libraries and the
dnl meta object compiler. If one of the options is given, the search is
dnl started in the given directory. If both options are given, no checks
dnl are performed and the cache is not consulted nor altered.
dnl
dnl The following shell variable is set to either "yes" or "no":
dnl
dnl have_qt
dnl
dnl Additionally, the following variables are exported:
dnl
dnl QT_CXXFLAGS
dnl QT_LIBS
dnl QT_MOC
dnl QT_DIR
dnl
dnl which contain an "-I" flag pointing to the Qt include directory, link flags
dnl necessary to link with Qt and X, the name of the meta object compiler
dnl with full path, and the variable QTDIR as Trolltech likes to see it
dnl defined, respectively.
dnl
dnl Example lines for Makefile.in:
dnl
dnl CXXFLAGS = @QT_CXXFLAGS@
dnl MOC = @QT_MOC@
dnl
dnl After the variables have been set, a trial compile and link is
dnl performed to check the correct functioning of the meta object compiler.
dnl If this test fails, a warning appears in the output of configure, but
dnl the variables remain defined.
dnl
dnl No common variables such as $LIBS or $CFLAGS are polluted.
dnl
dnl Options:
dnl
dnl --with-Qt-includes=DIR: DIR should point to where the Qt
dnl includes can be found, as in -IDIR.
dnl
dnl --with-Qt-dir=DIR: DIR should point to the "QTDIR", i.e.,
dnl libraries are in DIR/lib/.
dnl
dnl If at least one of the options "=no" or, equivalently,
dnl --without-Qt-includes and/or --without-Qt-dir is given, "have_qt" is set
dnl to "no" and the other variables are set to the empty string.
dnl
dnl Calls BNV_PATH_QT_DIRECT as a subroutine.
