# 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. |
