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.

At the moment our examples require a minimum of 3.14 due to changes
in upstream CMake's Autogen functionatlity to support Qt 6. Anything
lower would simply not work with Qt 6.
It's not clear yet if we actually want to require 3.14, or something
higher. At the very least there were many significant changes to
support iOS in CMake 3.15.
But for now just bump the version checked by Qt6Config.cmake to be
consistent with what's in our examples.

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.

mkspecs/features/qt.prf adds a dependency on the system threading
library if the Qt Core thread feature is enabled. Because qt.prf is
loaded by any public or internal Qt project, it's essentially a public
dependency for any Qt consumer.
To mimic that in CMake, we check if the thread feature is enabled, and
and set the Threads::Threads library as a dependency of Qt6::Platform,
which is a public target used by all Qt modules and plugins and Qt
consumers.
We also need to create a Qt6Dependencies.cmake file so we
find_package(Threads) every time find_package(Qt6) is called.
For the .prl files to be usable, we have to filter out some
CMake implementation specific directory separator tokens
'CMAKE_DIRECTORY_ID_SEP' aka '::@', which are added because we call
target_link_libraries() with a target created in a different scope
(I think).
As a result of this change, we shouldn't have to hardcode
Threads::Threads in other projects, because it's now a global public
dependency.

The default Info.plist shipped with CMake lacks an NSPrincipalClass
entry, which is crucial for making macOS apps run in full resolution
on retina screens.
We make sure the file is only picked up on macOS, not iOS and friends,
since those platforms require another principal class. If needed we can
extract the value out as a CMake variable and use the same file for all
Apple platforms. Doing so would assume all keys are single-platform
only, so if that's not the case we need platform-specific files.
We should probably extract the package type out as a variable too,
so that the file can be used for both apps, plugins, and frameworks,
but doing so requires setting up that variable somewhere based on
the target type, which CMake doesn't allow in an easy way.
The file itself is based on the file CMake ships, combined with
keys inherited from Qt's existing plist templates for qmake, and
adjusted to match what Xcode generates by default these days.

During a static build we need to use the find modules

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

In order for the macros to work, extract some of the variables

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
