# SYNOPSIS
#
# Check if a module exists:
# AX_CHECK_QT([qt_prefix], [list-of-qt-modules], [optional-modules] [flags])
#
# Abort if a module does not exist:
# AX_REQUIRE_QT([qt_prefix], [list-of-qt-modules], [optional-modules] [flags])
#
# DESCRIPTIONS
#
# qt_prefix
#
# Each call to AX_CHECK_QT should have a different prefix
# value (with a few exceptions discussed later on). This value,
# usually provided in uppercase, is used as prefix to the
# variables holding the compiler flags and libraries reported by
# pkg-config.
#
# For instance, if your prefix was to be FOO you'll be provided
# two variables FOO_CFLAGS and FOO_LIBS.
#
# This will also be used as message during the configure checks:
# checking for FOO....
#
# list-of-modules
#
# A single call to the macro can check for the presence of one or
# more qt modules; you'll see later how to make good use of this
# feature. Each entry in the list can have a version comparison
# specifier, with the same syntax as the Requires keyword in the
# data files themselves.
#
# optional-modules
#
# Optional list of more, optional modules, e.g. modules that
# exist only in Qt5, but not in Qt4, such as QtWidgets or
# QtWebKitWidgets
#
# flags
#
# Optional flages, space separated from this list:
#
# manualflags
#
# CXXFLAGS, CPPFLAGS and LIBS variables are not
# automatically expanded, but you need to add the
# qt_prefix_CXXFLAGS, qt_prefix_CPPFLAGS and qt_prefix_LIBS
# variables manually where you need them. This is useful,
# if some build targets need a feature and some don't.
