Use correct module include name across the project Module may have specific module include name that should be taken into account when specifying module include directories in different places. The INTERFACE_MODULE_INCLUDE_NAME module property name is aligned to the common naming rules and the property is used to preform include paths instead of the direct use of the module name. Add additional paths generated by qt_internal_module_info to keep them consistent across all cmake files.

Merge main and private targets of the internal modules In cmake, targets are used as an entity for modules. This causes a number of problems when we want to manipulate a module as a separate entity with properties associated with it. The _qt_internal_module_interface_name target property is introduced to represent the module entity. All modules write a name to this property, which will subsequently expand into the module name matched with the module name in qmake. The 'qt_internal_module_info' function is responsible for providing the correct values ​​for the module properties used when working with a module target. Unlike qmake, for internal modules in cmake it is expected that the Private suffix will be specified explicitly. In case the user wants to have a different module name, an additional argument MODULE_INTERFACE_NAME of the qt_internal_add_module function is introduced. This also changes the way how target dependencies are collected and resolved. Since the 'Private' suffix no longer means an unique identifier of the module 'Private' part, we look for the both Private and non-Private package names when resolving dependencies. TODO: This change doesn't affect the existing internal modules, so to keep compatibility with the existing code the existing internal modules create 'Private' aliases. The code that provides backward compatibility must be removed once all internal modules will get the proper names.

CMake: Make WrapVulkanHeaders target optional for QtGui consumers If Vulkan headers are present on the system when qtbase is configured, QtGui and QtOpenGL should be compiled with Vulkan support. If a user project uses a Qt built with Vulkan support, but their system is missing Vulkan headers, the project configuration needs to succeed. The project will get compilation errors if it uses Vulkan headers, but that's intended. This use case was broken when fixing Vulkan to be found when building Qt for Android. Fix the regression with a combination of things 1) Mark the WrapVulkanHeaders package as optional (already the case) 2) Use the include directories directly when compiling Gui and OpenGL 3) Propagate WrapVulkanHeaders::WrapVulkanHeaders link requirement to consumers only if the target exists. It won't exist if Vulkan include dirs are not found This also requires some changes in pri and prl file generation. For prl file generation, we don't want to link to the WrapVulkanHeaders target, so we filter out all dependencies that use TARGET_NAME_IF_EXISTS for anything that calls __qt_internal_walk_libs which includes qt_collect_libs. For pri files, we make sure to generate a uses=vulkan/nolink clause by inspecting a new _qt_is_nolink_target property on the target. We also don't add include dirs to the pri file if the new _qt_skip_include_dir_for_pri property is set. This is intended for Vulkan, because there is separate qmake logic to try and find the include dirs when configuring a user project. As a drive-by, fix nolink handling for WrapOpenSSLHeaders.

CMake: Make qt_internal_walk_libs available in public projects Needed for the upcoming static plugin mechanism, where we have to extract the list of Qt module dependencies of a target and then extract the plugins associated with those modules. To do that we need to recursively collect the dependencies of a given target. Rename the moved functions to contain the __qt_internal prefix. Also rename the existing QtPublicTargetsHelpers.cmake into QtPlatformTargetHelpers.cmake to avoid confusion with the newly introduced QtPublicTargetHelpers.cmake.

CMake: Export 3rdparty dependency find_package calls of private modules Consider a Qt module with a 3rdparty library target in PRIVATE_MODULE_INTERFACE, e.g. XKB::XKB in Qt6::GuiPrivate. Consumers of GuiPrivate automatically depend on XKB::XKB. In order to do that they must find_package(XKB ...). As all find_package calls for GuiPrivate are in the same place as the ones for Gui, this package must be marked as optional. Otherwise all consumers of Qt6::Gui would have to have the xkbcommon package installed too. This patch exports find_package calls for every 3rdparty public dependency of private modules and marks them as optional.

CMake: Fix Core -> Core dependency in static build Fix the overly strict regex in qt_internal_create_module_depends_file to allow for - and _ in module names. We had the above mentioned dependency cycle, because the module name Core_qobject was translated to just Core, creating a Core -> Core dependency. Amends da7609e7d0592b76ccb7cfb6c3136267172dc6bf.

CMake: Fix exclusion of QtFoo in QtBarDepends for 3rd party libs When configuring a static Qt with the -qt-zlib option and the build system creates a 3rd party header module QtZlib, syncqt does not generate a QtZlib header file that would include all its public headers. Then when the QtSvgDepends header is generated, it would add an #include <QtZlib> which would break compilation of the QtSvg PCH file (which compiles QtSvgDepends). We have logic to exclude addition of headers from regular 3rd party static libraries, but not header only 3rd party libraries. Adjust the code to handle header-only 3rd party libraries, as well as make sure it works across repos by exporting the relevant properties. As a drive-by, also rename and export some other informational properties.

Merge main and private targets of the internal modules In cmake, targets are used as an entity for modules. This causes a number of problems when we want to manipulate a module as a separate entity with properties associated with it. The _qt_internal_module_interface_name target property is introduced to represent the module entity. All modules write a name to this property, which will subsequently expand into the module name matched with the module name in qmake. The 'qt_internal_module_info' function is responsible for providing the correct values ​​for the module properties used when working with a module target. Unlike qmake, for internal modules in cmake it is expected that the Private suffix will be specified explicitly. In case the user wants to have a different module name, an additional argument MODULE_INTERFACE_NAME of the qt_internal_add_module function is introduced. This also changes the way how target dependencies are collected and resolved. Since the 'Private' suffix no longer means an unique identifier of the module 'Private' part, we look for the both Private and non-Private package names when resolving dependencies. TODO: This change doesn't affect the existing internal modules, so to keep compatibility with the existing code the existing internal modules create 'Private' aliases.

CMake: Export 3rdparty dependency find_package calls of private modules Consider a Qt module with a 3rdparty library target in PRIVATE_MODULE_INTERFACE, e.g. XKB::XKB in Qt6::GuiPrivate. Consumers of GuiPrivate automatically depend on XKB::XKB. In order to do that they must find_package(XKB ...). As all find_package calls for GuiPrivate are in the same place as the ones for Gui, this package must be marked as optional. Otherwise all consumers of Qt6::Gui would have to have the xkbcommon package installed too. This patch exports find_package calls for every 3rdparty public dependency of private modules and marks them as optional.

# Setup build and install paths
CMake: Fix QT_ADDITIONAL_PACKAGES_PREFIX_PATH for cross-builds The QT_ADDITIONAL_PACKAGES_PREFIX_PATH variable was introduced to allow specifying extra locations to find Qt packages. The reason it was introduced instead of just using CMAKE_PREFIX_PATH is because the Qt6 component find_package call uses NO_DEFAULT_PATH which means CMAKE_PREFIX_PATH is ignored. We use NO_DEFAULT_PATH to ensure we don't accidentally pick up system / distro Qt packages. The paths from QT_ADDITIONAL_PACKAGES_PREFIX_PATH are added to the find_package PATHS option in the Qt6 package, each ModuleDependencies.cmake file and some other places. Unfortunately that's not enough to make it work for cross-builds. Imagine the following scenario. host qtbase, qtdeclarative installed in /host_qt target qtbase installed in /target_qtbase target qtdeclarative installed in /target_qtdeclarative We want to cross-build qtlottie. We configure qtlottie as follows /target_qtbase/bin/qt-configure-module /qtlottie_src -- -DQT_ADDITIONAL_PACKAGES_PREFIX_PATH=/target_qtdeclarative We expect the target QtQuick package to be found, but it won't be. The reason is that QT_ADDITIONAL_PACKAGES_PREFIX_PATH is added to the PATHs option, but we don't adjust CMAKE_FIND_ROOT_PATH. Without adding the new paths in CMAKE_FIND_ROOT_PATH, CMake will re-root the passed PATHs under the existing CMAKE_FIND_ROOT_PATH, which is QT_TOOLCHAIN_RELOCATABLE_INSTALL_PREFIX, which evaluates to /target_qtbase. There is no QtQuick package there. To fix this, prepend the values of QT_ADDITIONAL_PACKAGES_PREFIX_PATH to CMAKE_FIND_ROOT_PATH. The location where we currently do CMAKE_FIND_ROOT_PATH manipulations is in the qt.toolchain.cmake file, so to be consistent, we prepend the new prefixes there as well. We need to adjust both CMAKE_FIND_ROOT_PATH and CMAKE_PREFIX_PATH, due the path re-rooting bug in CMake. See https://gitlab.kitware.com/cmake/cmake/-/issues/21937 as well as the existing comment in qt.toolchain.cmake marked with REROOT_PATH_ISSUE_MARKER. We also need to do a few more things to make the setup work Because Qt6Config uses NO_DEFAULT_PATH, the CMAKE_PREFIX_PATH adjustments we do in the toolchain file are not enough, so we still need to add the same prefixes to the Qt6Config find_package PATHS option. One would ask why do we need to adjust CMAKE_PREFIX_PATH at all then. It's for find_package(Qt6Foo) calls to work which don't go through the Qt6Config umbrella package. To make the CMake re-rooting behavior happy, we need to ensure the provided paths are absolute. So we iterate over the values of QT_ADDITIONAL_PACKAGES_PREFIX_PATH, to make them absolute. We do the same for the environment variable. We need to append lib/cmake to the prefixes which are added to CMAKE_PREFIX_PATH, otherwise the CMake re-rooting bug is hit. We need to specify the Qt6 package location (${_qt_cmake_dir}) to the PATHS option in the various Dependencies.cmake.in files, to ensure that dependency resolution can jump around between the Qt6 dir and the additional prefixes. Previously the dependency lookup code assumed that all dependencies would be within the same prefix. The same is needed for qt and qml plugin dependency lookup.

We need to adjust both CMAKE_FIND_ROOT_PATH and CMAKE_PREFIX_PATH, due the path re-rooting bug in CMake. See https://gitlab.kitware.com/cmake/cmake/-/issues/21937 as well as the existing comment in qt.toolchain.cmake marked with REROOT_PATH_ISSUE_MARKER. We also need to do a few more things to make the setup work Because Qt6Config uses NO_DEFAULT_PATH, the CMAKE_PREFIX_PATH adjustments we do in the toolchain file are not enough, so we still need to add the same prefixes to the Qt6Config find_package PATHS option. One would ask why do we need to adjust CMAKE_PREFIX_PATH at all then. It's for find_package(Qt6Foo) calls to work which don't go through the Qt6Config umbrella package. To make the CMake re-rooting behavior happy, we need to ensure the provided paths are absolute. So we iterate over the values of QT_ADDITIONAL_PACKAGES_PREFIX_PATH, to make them absolute. We do the same for the environment variable. We need to append lib/cmake to the prefixes which are added to CMAKE_PREFIX_PATH, otherwise the CMake re-rooting bug is hit. We need to specify the Qt6 package location (${_qt_cmake_dir}) to the PATHS option in the various Dependencies.cmake.in files, to ensure that dependency resolution can jump around between the Qt6 dir and the additional prefixes. Previously the dependency lookup code assumed that all dependencies would be within the same prefix. The same is needed for qt and qml plugin dependency lookup.

CMake: Export 3rdparty dependency find_package calls of private modules Consider a Qt module with a 3rdparty library target in PRIVATE_MODULE_INTERFACE, e.g. XKB::XKB in Qt6::GuiPrivate. Consumers of GuiPrivate automatically depend on XKB::XKB. In order to do that they must find_package(XKB ...). As all find_package calls for GuiPrivate are in the same place as the ones for Gui, this package must be marked as optional. Otherwise all consumers of Qt6::Gui would have to have the xkbcommon package installed too. This patch exports find_package calls for every 3rdparty public dependency of private modules and marks them as optional.

Fix loading of Qt6*Plugin.cmake files of per-repo builds When doing a per-repository build of Qt, as it is done for the installer packages, the build of qtbase has no knowledge of plugins that might be built and installed from other repositories. That means we must not write a fixed list of known plugins when exporting Qt modules of qtbase. In particular, qtsvg adds imageformat plugins that are supposed to be picked up by qtbase's QtGui module when linking a project against a statically linked Qt. ${install-prefix}/lib/cmake/Qt6Gui/Qt6GuiPlugins.cmake missed the include statements for qtsvg's plugin config files and operated on a fixed list of plugins, all from qtbase. Apart from that, the Qt6::Gui target's property QT_PLUGINS did only contain the qtbase plugins. This patch fixes the situation in the following way: 1. All Qt6*PluginConfig.cmake files in ${install-prefix}/lib/cmake/Qt6Gui are detected and included. 2. From those file names, the target names of the plugins are deduced. This is safe as the file name of those generated files is a direct result of the plugin's target name. 3. The QT_PLUGINS property of the module is updated with the detected plugin target names.

CMake: Fix building multi-arch universal macOS Qt Use the same approach we use for iOS, which is to set multiple CMAKE_OSX_ARCHITECTURES values and let the clang front end deal with lipo-ing the final libraries. For now, Qt can be configured to build universal macOS libraries by passing 2 architectures to CMake, either via: -DCMAKE_OSX_ARCHITECTURES="x86_64;arm64" or -DCMAKE_OSX_ARCHITECTURES="arm64;x86_64" Currently we recommend specifying the intel x86_64 arch as the first one, to get an intel slice configuration that is comparable to a non-universal intel build. Specifying the arm64 slice first could pessimize optimizations and reduce the feature set for the intel slice due to the limitation that we run configure tests only once. The first specified architecture is the one used to do all the configure tests. It 'mostly' defines the common feature set of both architecture slices, with the excepion of some special handling for sse2 and neon instructions. In the future we might want to run at least the Qt architecture config test for all specified architectures, so that we can extract all the supported sub-arches and instruction sets in a reliable way. For now, we use the same sse2 hack as for iOS simulator_and_device builds, otherwise QtGui fails to link due to missing qt_memfill32_sse2 and other symbols. The hack is somewhat augmented to ensure that reconfiguration still succeeds (same issue happened with iOS). Previously the sse2 feature condition was broken due to force setting the feature to be ON. Now the condition also checks for a special QT_FORCE_FEATURE_sse2 variable which we set internally. Note that we shouldn't build for arm64e, because the binaries get killed when running on AS with the following message: kernel: exec_mach_imgact: not running binary built against preview arm64e ABI. Aslo, by default, we disable the arm64 slice for qt sql plugins, mostly because the CI provisioned sql libraries that we depend on only contain x86_64 slices, and trying to build the sql plugins for both slices will fail with linker errors. This behavior can be disabled for all targets marked by qt_internal_force_macos_intel_arch, by setting the QT_FORCE_MACOS_ALL_ARCHES CMake option to ON. To disble it per-target one can set QT_FORCE_MACOS_ALL_ARCHES_${target} to ON.

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.

# Save minimum and policy-related CMake versions to ensure the same minimum is
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.

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.

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.

CMake: Fix exclusion of QtFoo in QtBarDepends for 3rd party libs When configuring a static Qt with the -qt-zlib option and the build system creates a 3rd party header module QtZlib, syncqt does not generate a QtZlib header file that would include all its public headers. Then when the QtSvgDepends header is generated, it would add an #include <QtZlib> which would break compilation of the QtSvg PCH file (which compiles QtSvgDepends). We have logic to exclude addition of headers from regular 3rd party static libraries, but not header only 3rd party libraries. Adjust the code to handle header-only 3rd party libraries, as well as make sure it works across repos by exporting the relevant properties. As a drive-by, also rename and export some other informational properties.

CMake: Move QtPostProcess functions into QtPostProcessHelpers.cmake The helpers can now be included manually in a project to call any required function. There was a use case for that in qttools, which was not possible because including QtPostProcess early would produce side effects.

Generate information about user-facing applications in build dir When packaging different Qt versions for Linux distributions (or any distribution with a common bin dir), Qt tools cannot be installed to /usr/bin, because the executable names of the different Qt versions clash. To solve this conflict, our recommendation is to install Qt's tools to /usr/lib/qt6/bin and to create versioned symlinks to user-facing tools in /usr/bin. User-facing tools are tools that are supposed to be started manually by the user. They are marked in Qt's build system. Distro package maintainers can now configure with -DCMAKE_INSTALL_PREFIX=/usr -DINSTALL_BINDIR=/usr/lib/qt6/bin -DINSTALL_PUBLICBINDIR=/usr/bin and will find a file called user_facing_tool_links.txt in the build directory after the cmake run. Nothing will be installed to INSTALL_PUBLICBINDIR. Each line of user_facing_tool_links.txt consists of the installation path of a user-facing application followed by a space and the versioned link name in INSTALL_PUBLICBINDIR. Example content: /usr/lib/qt6/bin/qmake /usr/bin/qmake6 To actually create the versioned symlinks, the content of this file can be fed to ln like this: xargs ln -s < build-dir/user_facing_tool_links.txt Or the package maintainer may decide to do something completely different as suits their needs. This patch adds the USER_FACING argument to qt_internal_add_tool to mark tools as user-facing. In addition, every Qt created by qt_internal_add_app is treated as user-facing. The only tool this patch marks as user-facing in qtbase is qmake.
