Export tool config and target files for each relevant module CMake will now generate config and target files for each module that provides tools. As a result, namespaced global targets such as Qt5::moc or Qt5::rcc can be made available. Third party projects that require just these tools, and not the Qt modules themselves, should specify CMAKE_PREFIX_PATH pointing to the installed Qt location, and call find_package(Qt5CoreTools), find_package(Qt5GuiTools), etc. It is also possible to call find_package(Qt5Tools REQUIRED Core Widgets) where the last option is a list of modules whose tools should be imported. Note that all the tools are in the Qt5:: namespace and not in the Qt5CoreTools:: or Qt5WidgetsTools:: namespace. This commit also changes the behavior regarding when to build tools while building Qt itself. When cross compiling Qt (checked via CMAKE_CROSSCOMPILING) or when -DQT_FORCE_FIND_TOOLS=TRUE is passed, tools added by add_qt_tool will always be searched for and not built. In this case the user has to specify the CMake variable QT_HOST_PATH pointing to an installed host Qt location. When not cross compiling, tools added by add_qt_tool are built from source. When building leaf modules (like qtsvg) that require some tool that was built in qtbase (like moc), the module project should contain a find_package(Qt5ToolsCore) call and specify an appropriate CMAKE_PREFIX_PATH so that the tool package is found. Note that because HOST_QT_TOOLS_DIRECTORY was replaced by QT_HOST_PATH, the ensure syncqt code was changed to make it work properly with both qtbase and qtsvg. Here's a list of tools and their module associations: qmake, moc, rcc, tracegen, qfloat16-tables, qlalr -> CoreTools qvkgen -> GuiTools uic -> WidgetTools dbus related tools -> DBusTools Task-number: QTBUG-74134 Change-Id: Ie67d1e2f8de46102b48eca008f0b50caf4fbe3ed Reviewed-by: Tobias Hunger <tobias.hunger@qt.io>

CMake: Enable NEW policies by CMake version with a global default When a CMake release introduces a new policy that affects most Qt modules, it may be appropriate to make each module aware of that newer CMake version and use the NEW policy without raising the minimum CMake version requirement. To reduce the churn associated with making that change across all Qt modules individually, this change allows it to be updated in a central place (qtbase), but in a way that allows a Qt module to override it in its own .cmake.conf file if required (e.g. to address the issues identified by policy warnings at a later time). The policies are modified at the start of the call to qt_build_repo_begin(). For commands defined by the qtbase module, qtbase needs to be in control of the policy settings at the point where those commands are defined. The above mechanism should not affect the policy settings for these commands, so the various *Config.cmake.in files must not specify policy ranges in a way that a Qt module's .cmake.conf file could influence. Starting with CMake 3.12, policies can be specified as a version range with the cmake_minimum_required() and cmake_policy() commands. All policies introduced in CMake versions up to the upper limit of that range will be set to NEW. The actual version of CMake being used only has to be at least the lower limit of the specified version range. This change uses cmake_minimum_required() rather than cmake_policy() due to the latter not halting further processing upon failure.
