cf96836018 Update start of cmake/README.md
Make the document reflect the current status of the port.

Also link to https://doc.qt.io/qt-6/build-sources.html  and
https://wiki.qt.io/Building_Qt_6_from_Git as official sources
on how to build Qt. This document should IMO rather
concentrate on documenting the build system internals.

fb21a5ce1a CMake: Name QT_NO_MAKE_*/BUILD_* variables consistently
For consistency, apply the following renamings:
QT_NO_MAKE_EXAMPLES -> QT_BUILD_EXAMPLES_BY_DEFAULT
QT_NO_MAKE_TESTS    -> QT_BUILD_TESTS_BY_DEFAULT
QT_NO_MAKE_TOOLS    -> QT_BUILD_TOOLS_BY_DEFAULT
BUILD_EXAMPLES      -> QT_BUILD_EXAMPLES
BUILD_TESTING       -> QT_BUILD_TESTS

This should help to better convey the difference between "BUILD" and
"NO_MAKE".

To configure tests, but not to build them by default, pass the
following to CMake:
-DQT_BUILD_TESTS=ON -DQT_BUILD_TESTS_BY_DEFAULT=OFF

Analoguous for examples:
-DQT_BUILD_EXAMPLES=ON -DQT_BUILD_EXAMPLES_BY_DEFAULT=OFF

Tools can be excluded from the default build with:
-DBUILD_TOOLS_BY_DEFAULT=OFF

The variable BUILD_TESTING is still available and initialized with the
value of QT_BUILD_TESTS.

557d2adbe8 CMake: Autodetect Android toolchain file and NDK
The Android toolchain file is now autodetected from the location of the
NDK. The NDK location can be specified by setting the CMake variable
ANDROID_NDK_ROOT. Auto-detection of the Android toolchain file is the
only purpose of this variable.

In recent Android SDK installations the path to the NDK is well-known
and can be auto-detected too. If only ANDROID_SDK_ROOT is given, we try
to detect ANDROID_NDK_ROOT first and from that the Android toolchain
file.

Adjust the build instructions in cmake/README.md, and remove the part
where we suggest to set some environment variables that are only used to
create the cmake call.

55a15a1c1b Add initial support for cross-building to iOS
Tested locally with the following configurations:
- iOS device builds (arm64)
- iOS simulator builds (x86_64)
- iOS simulator_and_device builds (fat arm64 and x86_64 archives)

All iOS builds currently require a custom vcpkg fork which contains
fixes for building the required 3rd party libraries.

qtsvg, qtdeclarative, qtgraphicaleffects and qtquickcontrols2
have also been tested to build successfully.

simulator_and_device builds are also supported, but require an umerged
patch in upstream CMake as well as further patches to vcpkg.

152b22a7b0 Android: Generate deployment-settings.json
Generate the android deployment settings json for android apk
targets. QtPlatformAndroid is now also deployed as a public
build dependency of QtCore. Some minor refactoring has been
performed to the naming of variables and functions to
better match the public facing apis.

Extra settings for the file can be configured using the
following target properties:

set_target_properties(Core
    PROPERTIES QT_ANDROID_DEPLOYMENT_DEPENDENCIES "foo;bar"
    QT_ANDROID_EXTRA_LIBS "foo;bar"
    QT_ANDROID_EXTRA_PLUGINS "foo;bar"
    QT_ANDROID_PACKAGE_SOURCE_DIR "/foo/bar/"
    )

The file is generated using the function
qt_android_generate_depoyment_settings().

We need to install the android template files and jar
files during the android build as the androiddeployqt tool
wont work if parts of it are split between the host
install and the android install.

Added QT_BUILD_QT variable to check whether we are building
Qt from source.

Finally, we also force the stdlib to shared via cmake
configuration with -DANDROID_STL="c++_shared"

42d3b21c92 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
