7e7f41e40c Pick the latest available C/C++ standard when compiling Qt
This maps the behavior of mkspecs/features/qt_common.prf and enables the
use of C++17 for example in Android, where the toolchain supports it
anyway.

981cfe7d79 Include QtPlatformSupport as part of find_package(Qt6BuildInternals)
This is needed because the ported over requires() clauses from qmake
to CMake are executed before qt_repo_build(), which means that all the
custom platform variables that we set (like LINUX, APPLE_OSX) need
to be available immediately after finding BuildInternals.

fbddf745e9 Create module tools packages (config files) automatically
Previously you had to make sure to use DISABLE_TOOLS_EXPORT
in an add_qt_module call if the tools are built after the module,
as well as to manually call qt_export_tools after all associated
tools are built.

This was needlessly complex, especially for people that are porting
a repo with tools for the first time.

The tools package creation is now automatically done at QtPostProcess
step, so there is no need to use either DISABLE_TOOLS_EXPORT or
qt_export_tools() manually.

DISABLE_TOOLS_EXPORT is now a no-op, and will be removed once all repos
are updated not to use it.

2cf0ba1fba Use pre-compiled headers when building Qt with cmake
Some modules define their own manually-maintained lists, and we can rely
on the headers generated by each module to include in the pch as well
e.g. QtCore/QtCore.

There's also e.g. QtWidgetDepends for QtWidgets, but this only
works for modules, not for tools, examples or other applications.
For now we'll use the Qt<Module>/Qt<Module> headers for the
modules we depend on.

Building with PCH can be disabled with -DBUILD_WITH_PCH=NO, and it only
works for versions of CMake newer than 3.15.20190829.

bf899ba53b Propagate BUILD_TESTING and BUILD_EXAMPLES
As with qmake, you configure with or without -nomake tests -nomake
examples, and the choice is propagated to other repositories.

Do the same for CMake. It's still possible to opt out to build one
or the other by passing -DBUILD_TESTING=OFF -DBUILD_EXAMPLES=OFF
on the command line, which takes precedence over the value saved to
QtBuildInternalsExtra.

f54881f73a Fix exporting of Core tools
It should happen after qmake is built, to make sure that the target is
made global, otherwise when cross-building qtbase in another build tree,
the configuration phase will fail due to not finding qmake.

qmake was accidentally exported before if you configured qtbase twice,
because the tool was kept around in a cache variable, the second
configuration actually recreated the CoreToolsConfig.cmake file to
contain qmake as well.

6732fa3a29 Fix linking of examples
Provide add_qt_gui_executable() as function in our public API that takes
care of automaticWinMain linkage. We can use this in the future to
encapsulate similarplatform-specific behavior and adjustments, such as
module generation onAndroid.

In order for the examples to see the function in Qt5CoreMacros, three more
additional fixes were required:

    * Do the build_repo_end() call _before_ attempting to build the
      examples, as we need the build_repo_end() to include QtPostProcess
      and complete the creation of all the target config files.
      Otherwise the find_package() calls in the examples see something
      incomplete.

    * Add more QT_NO_CREATE_TARGET guards

    * Always call find_dependency on the dependencies, regardless of the
      target creation mode. This way a find_package(Qt5 COMPONENTS
      Widgets) will still load Qt5CoreMacros.

c965137448 Fix build against sysroots

packages for cross-compiling, we need to temporarily change the mode to
BOTH to locate our build internals.

9542e78525 Use the qt_build_repo() macros for building qtbase as well
To implement this, create a new Qt5BuildInternals package.

All child Qt modules like qtsvg should use
find_package(Qt5BuildInternals) or
find_package(Qt5 COMPONENTS BuildInternals) in the their
top level CMakeLists.txt.
This will make the qt_build_repo() macros available.

For qtbase we slightly cheat, and specify a CMAKE_PREFIX_PATH
pointing to the source folder that contains the BuildInternals
package.

For the other modules we actually use a configured and installed
package Config file.

This change moves variables that used to be written into the
QtCore Config file into the BuildInternals package. This way
things that are relevant only for building additional Qt modules
does not pollute the QtCore package.

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

e0b4144486 Force feature_summary to fail when a required package is not found
Apparently calling set_package_properties with TYPE REQUIRED and
then calling feature_summary with FATAL_ON_MISSING_REQUIRED_PACKAGES
and PACKAGES_NOT_FOUND is not enough to make CMake fail when not
finding a required package.

You have to explicitly set REQUIRED_PACKAGES_NOT_FOUND to force
feature_summary to fail when a package is not found.

Do this, and also explicitly add the rest of the NOT FOUND cases,
to get a slightly clearer overview what kind of packages were not
found.
