CMake: Allow finding Qt CMake packages in additional locations By default, when using the Qt6 CMake package to look for components, the find_package() calls for the components use NO_DEFAULT_PATH to ensure that CMake doesn't accidentally find system (distro) packages. Instead we limit the paths to one level up from where the Qt6 package is. Unfortunately that doesn't quite work for finding Qt packages that might have been installed into a different prefix than where the main Qt prefix is. This happens when Qt addons are built by Conan, and installed into a separate prefix. To allow calls like find_package(Qt6 COMPONENTS ConanAddon) to work in a scenario as described above, introduce a new variable called QT_ADDITIONAL_PACKAGES_PREFIX_PATH which can be used to specify additional paths where Qt CMake packages should be found. This is similar to previously introduced QT_EXAMPLES_CMAKE_PREFIX_PATH variable which was meant for a similar case, but only for examples. Additionally, allow disabling the NO_DEFAULT_PATH option by setting the QT_DISABLE_NO_DEFAULT_PATH_IN_QT_PACKAGES cache variable to TRUE. This would allow regular usage of CMAKE_PREFIX_PATH to work, at the risk that system Qt CMake packages might be found.

Write find_dependency() calls in Qt Module config files This change introduces a new function called qt_find_package() which can take an extra option called PROVIDED_TARGETS, which associates targets with the package that defines those targets. This is done by setting the INTERFACE_QT_PACKAGE_NAME and INTERFACE_QT_PACKAGE_VERSION properties on the imported targets. This information allows us to generate appropriate find_dependency() calls in a module's Config file for third party libraries. For example when an application links against QtCore, it should also link against zlib and atomic libraries. In order to do that, the library locations first have to be found by CMake. This is achieved by embedding find_dependency(ZLIB) and find_dependency(Atomic) in Qt5CoreDependencies.cmake which is included by Qt5CoreConfig.cmake. The latter is picked up when an application project contains find_package(Qt5Core), and thus all linking dependencies are resolved. The information 'which package provides which targets' is contained in the python json2cmake conversion script. The generated output of the script contains qt_find_package() calls that represent that information. The Qt5CoreDependencies.cmake file and which which dependencies it contains is generated at the QtPostProcess stop. Note that for non-static Qt builds, we only need to propagate public 3rd party libraries. For static builds, we need all third party libraries. In order for the INTERFACE_QT_PACKAGE_NAME property to be read in any scope, the targets on which the property is set, have to be GLOBAL. Also for applications and other modules to find all required third party libraries, we have to install all our custom Find modules, and make sure they define INTERFACE IMPORTED libraries, and not just IMPORTED libraries.

When storing the INTERFACE_QT_PACKAGE_COMPONENTS property, make sure to store the entire list of components, not just the first component -- by turning the semi-colon separated list into a space separated list. When processing the components at find_dependency time, we need to reverse that and pass COMPONENTS directly to ensure a correct parameter expansion.

Make module package depend on its own tool package Also make the tool package depend on all tool packages that correspond to the qt module dependencies. So find_package(Qt5Widgets) implicitly calls find_package(Qt5WidgetTools). And find_package(Qt5WidgetsTools) will call find_package for Qt5GuiTools, and Qt5CoreTools. This enhances the user experience, so that in modules like qtsvg, you don't have to specify both find_package(Qt5Widgets) and find_package(Qt5WidgetsTools), but only the former. Or when cross building, you only need to specify Qt5WidgetTools, to get both Core and Gui tools. Change-Id: Ib1c5173a5b97584a52e144c22e38e90a712f727a Reviewed-by: Tobias Hunger <tobias.hunger@qt.io>

Fix tools dependencies lookup when cross-compiling When the host system uses 64-bits for pointers and the target 32-bits, then locating the tools dependencies would fail due to the mismatch.

CMake: Fix handling of CMAKE_FIND_ROOT_PATH and CMAKE_PREFIX_PATH While trying to implement the 'host artifact reuse' Coin instructions change, a bug surfaced where the qemu configurations didn't find the host tools and instead tried to use the cross-compiled tools while building qtbase, which failed due to not finding the runtime linker (another unsolved issue). Before the host artifact reuse change, the host tools were found successfully. The difference that caused the issue is that the target install prefix was a direct subfolder of the host prefix. host - /home/qt/work/qt/install target - /home/qt/work/qt/install/target Before the host reuse change the install prefixes were as follows host - /home/qt/work/qt/install/host target - /home/qt/work/qt/install/target While looking for the Qt6CoreTools package, we temporarily set CMAKE_FIND_ROOT_PATH and CMAKE_PREFIX_PATH to contain first '/home/qt/work/qt/install' and then '/home/qt/work/qt/install/target'. CMake then reroots the CMAKE_PREFIX_PATH values onto values in CMAKE_FIND_ROOT_PATH, making an MxN list of prefixes to search. Rerooting essentially means concatenating 2 paths, unless the considered prefix is a subfolder of the root path. What happened was that the first considered value was '/home/qt/work/qt/install/home/qt/work/qt/install', a non-existent location that gets discarded. The second considered value was '/home/qt/work/qt/install/target. The second value is the result of seeing that '/home/qt/work/qt/install/target' is a subfolder of '/home/qt/work/qt/install' and thus the root path is stripped. All of this is done in cmFindPackageCommand::FindConfig() -> cmFindCommon::RerootPaths. The behavior above caused the target tools be found instead of the host ones. Before the host reuse change, both of the initial constructed prefixes were discared due to them not existing, e.g. '/home/qt/work/qt/install/target/home/qt/work/qt/install/target' and '/home/qt/work/qt/install/host/home/qt/work/qt/install/host' One of the later prefixes combined CMAKE_FIND_ROOT_PATH == '/home/qt/work/qt/install/host' + CMAKE_PREFIX_PATH == '/' resulting in '/home/qt/work/qt/install/host/' and this accidentally found the host tools package. We actually stumbled upon this issue a while ago when implementing Qt 5.14 Android CMake support in 52c799ed4425076df4353c02950ea1444fe5f102 That commit message mentions the fix is to add a "lib/cmake" suffix to the PATHS option of find_package(). This would cause the subfolder => strip root behavior mentioned above. So finally the fix. First, make sure not to append QT_HOST_PATH in the toolchain file, there shouldn't be any need to do that, give that we temporarily set it when looking for Tools packages. Second, recreate the subdir scenario in the Qt toolchain file by setting CMAKE_FIND_ROOT_PATH to the current (relocated) install prefix as usual, but also setting CMAKE_PREFIX_PATH to a new value poining to the CMake directory. Aka '/home/alex/qt' and '/home/alex/qt/lib/cmake'. Third, when a QT_HOST_PATH is given, save 2 paths in the generated Qt toolchain: QT_HOST_PATH and QT_HOST_PATH_CMAKE_DIR. There are the host equivalents of the target ones above. Use these values when looking for host tools in Qt6CoreModuleDependencies.cmake, again facilitaing the subdir behavior. Note these are currently absolute paths and are not relocatable. We'll have to figure out if it's even possible to make the host path relocatable. Finally as a cleanup, look for the Qt6HostInfo package in QtSetup strictly in the given QT_HOST_PATH, so CMake doesn't accidentally find a system Qt package.

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: Allow finding Qt CMake packages in additional locations By default, when using the Qt6 CMake package to look for components, the find_package() calls for the components use NO_DEFAULT_PATH to ensure that CMake doesn't accidentally find system (distro) packages. Instead we limit the paths to one level up from where the Qt6 package is. Unfortunately that doesn't quite work for finding Qt packages that might have been installed into a different prefix than where the main Qt prefix is. This happens when Qt addons are built by Conan, and installed into a separate prefix. To allow calls like find_package(Qt6 COMPONENTS ConanAddon) to work in a scenario as described above, introduce a new variable called QT_ADDITIONAL_PACKAGES_PREFIX_PATH which can be used to specify additional paths where Qt CMake packages should be found. This is similar to previously introduced QT_EXAMPLES_CMAKE_PREFIX_PATH variable which was meant for a similar case, but only for examples. Additionally, allow disabling the NO_DEFAULT_PATH option by setting the QT_DISABLE_NO_DEFAULT_PATH_IN_QT_PACKAGES cache variable to TRUE. This would allow regular usage of CMAKE_PREFIX_PATH to work, at the risk that system Qt CMake packages might be found.

CMake: Provide old style CMake variables for target info This change provides the following per-module variables Qt6Widgets_LIBRARIES, Qt6Widgets_INCLUDE_DIRS, Qt6Widgets_DEFINITIONS, Qt6Widgets_COMPILE_DEFINITIONS, Qt6Widgets_PRIVATE_INCLUDE_DIRS. These are deprecated and are only intended for easier porting from Qt5 to Qt6. Qt consumers should instead rely on the Qt module targets e.g target_link_libraries(app PRIVATE Qt6::Widgets) Note that the variable contents includes transitive values for everything except the _LIBRARIES variant. So Qt6Widgets_INCLUDE_DIRS will contain values for Widgets, Gui and Core. Qt6Widgets_LIBRARIES only contains a value like Qt6::Widgets, and when that is used in target_link_libraries(), CMake will take care of the transitivity.
