# SYNOPSIS
#
# AX_CXX_CHECK_QT([qt_prefix], [list-of-qt-modules])
#
# DESCRIPTIONS
#
# qt_prefix
#
# Each call to AX_CXX_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.
