CMake: Fix linking of qtsvg static plugins in standalone tests build Our QtPluginConfig.cmake.in files have code to skip loading plugins unless the repo is found in the QT_REPO_DEPENDENCIES variable or when building standalone parts. The problem is that QT_INTERNAL_BUILD_STANDALONE_PARTS is only assigned a value after all the find_package calls have executed, which is too late for the qtsvg standalone tests, because the svg icon config file would already be loaded and skipped. This code path checked for QT_BUILD_STANDALONE_TESTS, before the introduction of the QT_INTERNAL_BUILD_STANDALONE_PARTS variable. QT_BUILD_STANDALONE_TESTS is set by the qt-internal-configure-tests script, so it is always available. Restore the previous check for QT_BUILD_STANDALONE_TESTS, while keeping the new variable as well. This fixes the tst_qicon_svg test to pass in a static standalone tests build.

Fix error when re-configuring an already installed Qt repository When building and installing a Qt repo that provides plugins for a Qt module within a different repository (for example, qtimageformats providing imageformat plugins for QtGui), re-configuring that repository would result in configuration errors like "add_library cannot create ALIAS target "Qt6::QTgaPlugin" because another target with the same name already exists." This happened, because the find_package(Qt6 COMPONENTS Gui) calls pulled in the Qt6*PluginConfig.cmake files that create imported targets for the plugins we want to build. To fix this, when building Qt, we now load only plugins that are provided by repositories the currently building repository depends on. We read the repo dependencies from dependencies.yaml when the Qt6BuildInternals package is loaded, but only in static builds and only if we're currently building a Qt repository. To find out whether we're building a Qt repository, we check whether QT_REPO_MODULE_VERSION is defined. We cannot check QT_BUILDING_QT, because that variable is not available for the first find_package calls in the repository's top-level project file. In each Qt6*PluginConfig.cmake file, we bail out if the plugin's repository is not one of the ones in QT_REPO_DEPENDENCIES.

Avoid creating the installed test plugins when configuring standalone tests When configuring standalone tests with some installable plugins, these plugins land inside the actual build/install directory after build/installation. This makes imposible to configure the same standalone tests second time since the same plugin targets attempt to be created within the build tree, while they are already found by the respective find_package(<Qt Module>) call. This change introduces and uses the tests-wide qt_internal_configuring_tests variable to mark the plugins that are built within the tests build tree and disallows loading them by the find_package call when building standalone tests. The trick is simple: PluginConfig.cmake files skip plugin creation if the respective plugin is a test plugin and the standalone test project matches the plugin repo project. Also we now oblige module maintainers to mark such plugins using the TEST_PLUGIN argument of the qt_internal_add_plugin function. This is needed to prevent breakage when the exact test is build alone and the qt_internal_configuring_tests is not set. If plugin is not marked as TEST_PLUGIN and is built as part of test build tree the warning is displayed to remind the maintainer about the missing flag. Suggest to make this flag mandatory for all test plugins, and throw a FATAL_ERROR if the plugin is not marked respectively.

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: Prepare ground work for static Qml plugins importing For qt_import_qml_plugins to work, it needs to have access to the Qml plugin targets by the time find_package(Qt6Qml) is called. To do that, we modify the generation of Qml plugin Config, Targets and Dependencies files to go into a special 'QmlPlugins' subfolder of the Qml package. The Qml package will then GLOB include all the Config files in that folder, to make them available whenever find_package(Qt6Qml) is called. This is similar to how the Qt plugins were glob included in the CMake integration of Qt 5.15. In fact that glob including is missing in Qt 6 for regular Qt plugins, and should be implemented in a following change. Currently the Qt Plugins config files that are included are hardcoded to the list of known plugins at Qt configuration time. As a drive-by to make this all work, the naming of the various Config and Dependencies files has been normalized to include the Qt6 prefix. This is done for both regular Qt plugins and Qml plugins.

Avoid creating Plugin targets if the dependencies are missing The plugin lookup mechanism doesn't handle the situation, when the plugin is available but it's private dependency(static plugin case) is missing. In this case we currently silently bypass the dependency lookup and create targets. So users see the confusing message about missing linked target, like: Qt6QSQLiteDriverPluginTargets.cmake:61 (set_target_properties): The link interface of target "Qt6::QSQLiteDriverPlugin" contains: SQLite::SQLite3 but the target was not found. Possible reasons include: * There is a typo in the target name. * A find_package call is missing for an IMPORTED target. * An ALIAS target is missing. This indeed should be handled properly and we should omit creating targets especially if users don't really use the plugin directly. Also if dependencies are not satisfied it looks logically to set the <plugin>_FOUND to false as this will be yet another indicator for user that the plugin is not found.
