5a779a4ad3 CMake: Make it possible to build tools when cross-compiling
This patch allows tools to be built for the target platform when the
QT_BUILD_TOOLS_WHEN_CROSSCOMPILING parameter is set at configuration
time.

To avoid naming conflicts, the target tools are suffixed with "_native".
The qt_get_tool_target_name() function can be used to get the tool name
for both scenarios (cross and non-cross compilation).

Extend pro2cmake to refer to the right target name for tools.
The relevant write_XXX functions have a new target_ref parameter that
will be "${target_name}" for tools and literally the target name for
everything else.

Fixes: QTBUG-81901

0ceef4cb54 Always append extra cmake modules to CMAKE_MODULE_PATH in Qt6Config
During a static build we need to use the find modules
in 3rdparty/extra-cmake-modules/find-modules when generating a
ModuleDependencies file, so that the generated find_dependency()
calls succeed. This means that the files have to be shipped with
Qt6 package, making them pseudo public API.

There is also a need to use these files when building QtWayland.

Instead of setting / unsetting CMAKE_MODULE_PATH only in module
and plugin Dependencies cmake files, just set them once when finding
Qt6.

This will allow QtWayland and QtX11Extras to easily find the required
third party packages, without having to hardcode the paths in multiple
repos.

ffe0889413 Fix examples find_package calls to work in prefix builds
To build examples as part of a non-installed Qt prefix build,
not-yet-installed Config files need to be found by find_package()
calls inside example projects.

Facilitate that by propagating the CMAKE_PREFIX_PATH and
QT_EXAMPLES_CMAKE_PREFIX_PATH paths in all relevant find_package()
calls where NO_DEFAULT_PATH is used.

Also adjust the inclusion of the QtFeature.cmake file to be relative
to the qt6 directory, rather than the current list directory.
This is needed to successfully find the file when parsing a Config
file from a non-installed build directory.

6290efc4eb Fix building against an installed static Qt
For ICU we have multiple components, and ICU becomes a public dependency
to QtCore.

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.

03aa74e40d 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.
Since the tools dependencies don't create linkable targets but merely
import executables, we can skip this check like in commit
914b367c7f.

fe3bd212fc Merge remote-tracking branch 'origin/wip/qt6' into wip/cmake
This changes many different CMake places to mention Qt6 instead of
Qt5.

Note that some old qt5 cmake config files in corelib are probably not
needed anymore, but I still renamed and kept them for now.

fecd9d90da Fix static usage requirements for XcbQpa
In particular, Qt targets extended with other qt targets
(eg. Qt::VulkanSupport or Qt::LinuxAccessibilitySupport)
after the first add_qt_module were not taken into account when generating
Depends files.

Note that this patch updates the minimum required version
to CMake 3.15

bcfc3dca5d 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.

9b0b464e82 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.
