CMake: Bump the minimum required CMake version to build Qt to 3.18 Add a new function that returns the minimum CMake version required to build Qt. Pass that value to cmake_minimum_required() when building qtbase and its standalone tests. The minimum supported CMake version is read from qtbase/.cmake.conf and its value should be updated when the need arises. It's the main source of truth for all repos. Provide a way to lower the minimum CMake version at configure time by passing a value via QT_FORCE_MIN_CMAKE_VERSION. This is not an officially supported way of building Qt. If the specified version is lower than Qt's supported minimum, show a warning. Nevertheless the option is useful for testing how Qt builds with a different minimum CMake version due to different policies being enabled by default. Issue warnings for CMake versions that are higher than the minimum version but are known to cause issues when building Qt. A counterpart change is needed in qt5 to ensure the minimum CMake version is set at the proper time for top-level builds. Ideally we would use the same 'check the CMake minimum version` code in all our repositories, but that will cause lots of duplication because we can't really find_package() the code and doing something like include(../qtbase/foo.cmake) hardcodes assumptions about repo locations. So for now we don't bump the minimum version in child repo cmake_minimum_required calls (qtsvg, qtdeclarative, etc). Instead we record both the minimum supported version and the computed minimum version (in case a different version was forced) in QtBuildInternalsExtra.cmake. Then we require qtbase's computed min version in qt_build_repo_begin(). This won't set policies as cmake_minimum_required would, but at least it propagates what minimum CMake version should be used for child repos. We might still have to bump the versions in child repos at some point.

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.

CMake: Enforce minimum CMake version in user projects This change introduces new behavior to error out when configuring user projects if the CMake version used is too old for Qt to work with. The main motivator is the requirement of new CMake features to ensure object libraries are placed in the proper place on the link line in static builds. The minimum CMake version is computed based on whether Qt was configured as shared or static libraries. At the moment the required versions for building and using Qt are the same. The minimum versions are defined in qtbase/.cmake.conf in the following variables QT_SUPPORTED_MIN_CMAKE_VERSION_FOR_BUILDING_QT_SHARED QT_SUPPORTED_MIN_CMAKE_VERSION_FOR_BUILDING_QT_STATIC QT_SUPPORTED_MIN_CMAKE_VERSION_FOR_USING_QT_SHARED QT_SUPPORTED_MIN_CMAKE_VERSION_FOR_USING_QT_STATIC Qt Packagers can disable the version check when configuring Qt by setting QT_FORCE_MIN_CMAKE_VERSION_FOR_BUILDING_QT and QT_FORCE_MIN_CMAKE_VERSION_FOR_USING_QT. In this case it is the packagers responsibility to ensure such a Qt works correctly with the specified CMake version. User projects can also set QT_FORCE_MIN_CMAKE_VERSION_FOR_USING_QT to disable the version check. Then it's the project's developer responsibility to ensure such a Qt works correctly. No official support is provided for these cases. Implementation notes. The versions required to build Qt are stored in QtBuildInternalsExtra.cmake whereas the versions required to use Qt are stored in a new QtConfigExtras.cmake. Also the policy range variables stored in QtBuildInternalsExtra.cmake are now regular variables instead of cache variables, to properly allow overrides per-repository. Some renaming of functions and variables was done for a bit more clarity and easier grep-ability.

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>

Make standalone tests build via top level repo project Previously repo/tests/CMakeLists.txt was a standalone project on which CMake could be called. This was useful for Coin to be able to build and package only tests, but was a bit troublesome because that means having to specify the usual boilerplate like minimum CMake version, which packages to find in every tests.pro project. Instead of having a separate standalone project, modify the top level project and associated CMake code to allow passing a special QT_BUILD_STANDALONE_TESTS variable, which causes the top level project to build only tests, and find Qt in the previously installed qt location. This also means that when building a repo, we generate a ${repo_name}TestsConfig.cmake file which does find_package on all the modules that have been built as part of that repo. So that when standalone tests bare built for that repo, the modules are automatically found. qt_set_up_standalone_tests_build() is modified to be a no-op because it is not needed anymore. Its usage should be removed from all the other repos, and then removed from qtbase. Non-adjusted tests/CMakeLists.txt projects in other repositories should still be buildable with the current code, until they are updated to the new format. Adjust the Coin build instructions to build the standalone tests in a separate directory. Adjust pro2cmake to generate new structure for the tests/tests.pro projects. Adjust the qtbase tests project.
