# =========================================================================== # https://www.gnu.org/software/autoconf-archive/ax_have_qt.html # =========================================================================== # # SYNOPSIS # # AX_HAVE_QT # # DESCRIPTION # # Searches $PATH and queries qmake for Qt include files, libraries and Qt # binary utilities. The macro only supports Qt5 or later. # # The following shell variable is set to either "yes" or "no": # # have_qt # # Additionally, the following variables are exported: # # QT_CXXFLAGS # QT_LIBS # QT_MOC # QT_UIC # QT_LRELEASE # QT_LUPDATE # QT_DIR # # which respectively contain an "-I" flag pointing to the Qt include # directory, link flags necessary to link with Qt and X, the full path to # the meta object compiler and the user interface compiler both, and # finally the variable QTDIR as Qt likes to see it defined. # # Example lines for Makefile.in: # # CXXFLAGS = @QT_CXXFLAGS@ # MOC = @QT_MOC@ # # After the variables have been set, a trial compile and link is performed # to check the correct functioning of the meta object compiler. This test # may fail when the different detected elements stem from different # releases of the Qt framework. In that case, an error message is emitted # and configure stops. # # No common variables such as $LIBS or $CFLAGS are polluted. # # LICENSE # # Copyright (c) 2008 Bastiaan Veelo # Copyright (c) 2014 Alex Henrie # # Copying and distribution of this file, with or without modification, are # permitted in any medium without royalty provided the copyright notice # and this notice are preserved.
