## Add some paths to check for cmake modules:

"${CMAKE_CURRENT_SOURCE_DIR}/cmake"
"${CMAKE_CURRENT_SOURCE_DIR}/cmake/3rdparty/extra-cmake-modules/find-modules"
"${CMAKE_CURRENT_SOURCE_DIR}/cmake/3rdparty/kwin"

## Find the build internals package.
set(QT_BUILD_INTERNALS_SKIP_CMAKE_MODULE_PATH_ADDITION TRUE)
list(PREPEND CMAKE_PREFIX_PATH
"${CMAKE_CURRENT_SOURCE_DIR}/cmake"

## QtBase specific configure tests:
include(QtBaseConfigureTests)
## Build System tests:
include(QtBaseCMakeTesting)
## Targets for global features, etc.:
include(QtBaseGlobalTargets)
## Should this Qt be static or dynamically linked?
option(BUILD_SHARED_LIBS "Build Qt statically or dynamically" ON)
set(QT_BUILD_SHARED_LIBS ${BUILD_SHARED_LIBS})
## Should this Qt be built with Werror?
option(WARNINGS_ARE_ERRORS "Build Qt with warnings as errors" ${FEATURE_developer_build})
## Should Qt be built using PCH?
option(BUILD_WITH_PCH "Build Qt using precompiled headers?" ON)
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>
