dnl @synopsis BNV_HAVE_QT [--with-Qt-include-dir=DIR] [--with-Qt-bin-dir=DIR] [--with-Qt-lib-dir=DIR] [--with-Qt-lib=LIB]
dnl
dnl Search for Trolltech's Qt GUI framework.
dnl
dnl Searches common directories for Qt include files, libraries and Qt binary
dnl utilities. The macro supports several different versions of the Qt
dnl framework being installed on the same machine.
dnl Without options, the macro is designed to look for the latest library,
dnl i.e., the highest definition of QT_VERSION in qglobal.h.
dnl By use of one or more options a different library may be selected. There
dnl are two different sets of options.
dnl Both sets contain the option --with-Qt-lib=LIB which can be used to
dnl force the use of a particular version of the library file when more than
dnl one are available. LIB must be in the form as it would appear behind the
dnl "-l" option to the compiler. Examples for LIB would be "qt-mt" for the
dnl multi-threaded version and "qt" for the regular version.
dnl In addition to this, the first set consists of an option --with-Qt-dir=DIR
dnl which can be used when the installation conforms to Trolltech's standard
dnl installation, which means that header files are in DIR/include, binary
dnl utilities are in DIR/bin and the library is in DIR/lib.
dnl The second set of options can be used to indicate individual locations
dnl for the header files, the binary utilities and the library file, in
dnl addition to the specific version of the library file.
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_UIC
dnl QT_DIR
dnl
dnl which respectively contain an "-I" flag pointing to the Qt include
dnl directory, link flags necessary to link with Qt and X, the name of the
dnl meta object compiler and the user interface compiler both with full path,
dnl and finaly the variable QTDIR as Trolltech likes to see it defined (if
dnl possible).
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 This test may fail when the different detected elements stem from
dnl different releases of the Qt framework. In that case, an error message
dnl is emitted and configure stops.
dnl
dnl No common variables such as $LIBS or $CFLAGS are polluted.
dnl
dnl Options:
dnl
dnl --with-Qt-dir=DIR: DIR is equal to $QTDIR if you have followed the
dnl installation instructions of Trolltech. Header files are in DIR/include,
dnl binary utilities are in DIR/bin and the library is in DIR/lib.
dnl
dnl --with-Qt-include-dir=DIR: Qt header files are in DIR.
dnl
dnl --with-Qt-bin-dir=DIR: Qt utilities such as moc and uic are in DIR.
dnl
dnl --with-Qt-lib-dir=DIR: The Qt library is in DIR.
dnl
dnl --with-Qt-lib=LIB: Use -lLIB to link with the Qt library.
dnl
dnl If some option "=no" or, equivalently, a --without-Qt-* version is given
dnl in stead of a --with-Qt-*, "have_qt" is set to "no" and the other
dnl variables are set to the empty string.
dnl
dnl Calls BNV_PATH_QT_DIRECT as a subroutine.
