Depending on CMake version suggest usage of either
--debug-find-pkg or CMAKE_FIND_DEBUG_MODE to help troubleshoot
why dependent packages are not found.
To achieve that, append the hint message to the _NOT_FOUND_MESSAGE.
To ensure it works for qt dependencies, and not only tool and 3rd
party dependencies, _qt_internal_find_qt_dependencies
is modified to set variable names infixed by the target name, so the
name is consistent with the other dependency lookup functions.
The check and message are also added when a Qt6 component is not
found.

Aside from moving the code to reduce duplication, the only changes in

with variable names to avoid macro expansion issues and replacing

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.

separators, so that they can be used similar to CMAKE_PREFIX_PATH.

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.

Every public dependency of a Qt module results in a find_package call in
the consuming project. But not all public dependencies are mandatory.
For example, vulkan is only needed if the user project actually uses Qt
classes that pull in vulkan headers.
This patch adds the option MARK_OPTIONAL to qt_find_package.
Dependencies that are marked as optional will not produce an error on
find failure.

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.

Generated plugin CMake files should always try to call
find_dependency, especially in static builds.
pkg_check_modules sets a cache value for foo_FOUND instead of
a directory scope foo_FOUND, which means that find_dependency
will not be called in another scope, and thus fail to create
needed imported targets.
Note this makes the code be the same as in
ModuleDependencies.cmake.in.

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.

To build examples as part of a non-installed Qt prefix build,

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.

When processing the components at find_dependency time, we need to
