ce9799e4c4 MSVC: Fix the CET parameters
To enable CET for MSVC, only passing "/CETCOMPAT" to
the linker should be sufficient.

Enabling generation of EH Continuation (EHCONT) metadata
is additional protection and should not be necessary.
It also requires all the dependencies to be re-compiled
with EHCONT enabled, otherwise the linker will refuse
to link the obj files. However, this is rather hard
to achieve if your application depends on many 3rd-party
libraries, so to let people enable CET more freely,
we don't enable EHCONT guard by default.

dcc691c77d Add qt.pointer.dispatch debug message for tablet->mouse synth
We have one for touch->mouse synthesis, so perhaps it's a good idea here
too; then we can confirm that it's missing on Windows, because Windows
normally does the synthesis (setPlatformSynthesizesMouse(false) is not
called on this platform, so the default is true, meaning we expect that
it does that). The cross-platform synthesis (and ability for a platform
plugin to disable) began with f931e5e72d

d6b38be3df Port qt_repeatCount() to qsizetype
While it's true that the typical user of the function won't expect
more than half a dozen repeats, this function is fed with
user-supplied input, so it could be asked to return in excess of
INT_MAX matches. The truncation then means we're misreporting the
number mod INT_MAX, which is as good as a random number and leads to
false positive matches in users of the function.

Just return the true result instead of a truncated one.

Most defines are not needed, either, because clang based qdoc

Q_CLANG_QDOC is actually set by qdoc itself.

What's left is Q_GUI_LIB, Q_WIDGETS_LIB, which is used in headers
modules to make some API conditionally available. Finally, there's
QT_KEYPAD_NAVIGATION, which seems to be a Qt 3 thing, but still
some documentation depending on it ;)

749b2df889 QCollator: port compare(ptr, n, ptr, n) to qsizetype
While the function is inline, the class is exported wholesale, so the
function forms part of the ABI on Windows (but not Unix), so we must
overload, can't replace.

To avoid ambiguities where users pass different integer types as the
lengths of the LHS and RHS strings, QT_REMOVED_SINCE the old overload.

Since the removed function has an inline definition, it suffices to
just include the header into the corresponding QT_REMOVED_SINCE
section of the removed_api.cpp file, to elegantly solve the BiC
problem only for those platforms (MSVC) where it matters.

0a3ff69738 Long live QT6_{DECL,IMPL,CALL}_NEW_OVERLOAD!
We have in the past found ourselves in need of disambiguating new
overloads from older, QT_REMOVED_SINCE'ed ones, which we usually did
by adding a defaulted int argument, cf. e.g. QMetaType::id().

The problem with a defaulted int argument is twofold: First, an int is
a valid argument type, and users may get confused as to its meaning
when presented with the signature in the IDEs auto-completion popup,
and a lot of things implicitly convert to an int, so any errornous
parameter passing may stay unnoticed until we remove these fake
arguments come Qt 7.

Second, this way of doing things requires a lot of ifdef'ery to keep
the additional argument out of both the docs and future Qt 7 builds.

The solution presented in this patch is to create a tag type,
QDisambiguated_t, which a) more clearly communicates its purpose and
b) doesn't implicitly convert from anything.

To help with the invariably ugly ifdef'ery, provide a set of macros
that hide this stuff from qdoc and Qt 7 builds.

Use the macros to replace the fake int arguments that were added for
6.4.

5ea7e3a811 Windows: better handling of darkmode support
43ef22045c turned dark mode support on for
both styling and window frames. However, the default palette and style
support in Qt is too incomplete, resulting in unreadable UIs when using
certain styles (e.g. fusion). Also the vista style is not supporting
dark mode.

If we don't turn on dark style support, then dark frame support doesn't
look good either. However, many application developers have implement a
dark theme themselves, and we should have a dark frame for those
applications.

So partially revert 43ef22045c so that
dark style support is disabled by default, and leave dark frame support
on. However, only activate dark frames if the palette is dark, i.e. if
the window background color in the default palette is darker than the
text color (or if DarkModeStyle is explicitly turned on by running the
application with -platform windows:darkmode=2).

This way, dark-themed applications get a dark frame on dark Windows, and
a light frame on light Windows; and light-themed applications (including
default Qt applications) get a light frame all the time.

0d91f85f6c CMake: Introduce QT_DEBUG_FIND_PACKAGE for troubleshooting
When a Qt component or dependency is not found, we will now show a
message that the user can reconfigure the project with
-DQT_DEBUG_FIND_PACKAGE=ON.

If the option is enabled, various variables that find_package uses to
find packages (like CMAKE_PREFIX_PATH, CMAKE_FIND_ROOT_PATH) will be
recorded before each find_package / find_dependency call that is
executed in any of the Qt package files.

If any find_package call fails (a package has its _FOUND variable set
to 0), the values of all those recorded variables will be shown.

This is useful to troubleshoot issues, especially when
cross-compiling, without having to manually modify the various
Config files.

50d0296ed4 CMake: Suggest hints on how to debug missing packages
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.

0e2b385c5b CMake: Allow setting Qt6_DIR to find packages when not cross-compiling
So far we always recommended that developers set CMAKE_PREFIX_PATH to
point to the location of the Qt installation so that Qt packages are
found by CMake.

In Qt5 one could also set the Qt5_DIR variable to $qt/lib/cmake/Qt5
to allow the following signature to work:
 find_package(Qt5 COMPONENTS Core)

This was not sufficient in Qt6 because the CoreTools dependency would
not be found.

Fix this by also looking into the parent folder of
CMAKE_CURRENT_LIST_DIR as well as _qt_cmake_dir, like we already do
for regular non-Tools packages in _qt_internal_find_dependencies.

Note that setting Qt6_DIR is not sufficient for cross-compilation if
the qt.toolchain.cmake file is not used.
Aside from platform specific options that would have to be passed
manually to CMake (like -DCMAKE_SYSTEM_NAME=iOS for iOS) and
passing a QT_HOST_PATH value, the code would also need to be
adapted to do the necessary CMAKE_FIND_ROOT_PATH manipulations
to ensure that dependent packages are found.

f0c3cfb067 CMake: Display reason when a Qt*Tools package is not found
When a package's tools dependency is not found (e.g. Core's CoreTools)
set the _NOT_FOUND_MESSAGE variable the same way that find_dependency
does.
We can't use find_dependency directly because that returns immediately
without allowing us to reset the prefix paths vars.

db07310c51 CMake: Don't propagate REQUIRED to find_dependency / find_package
If find_package(Qt6 REQUIRED COMPONENTS Core) is called, don't
propagate the REQUIRED option to all the dependencies of Core,
regardless if it's a 3rd party library, tool or another Qt package
dependency.

Propagating REQUIRED causes the find_dependency -> find_package call
to exit the calling file immediately when the package is not found,
not giving an opportunity for find_dependency to set the
_NOT_FOUND_MESSAGE variable.

Instead force all find_dependency / find_package calls
to be optional, set the calling _FOUND variable to FALSE if the
dependency is not found, also set the _NOT_FOUND_MESSAGE variable.
Then the find_package call that loaded FooModuleConfig.cmake file
will show that message as the reason for the package not being
found.

ecfc0df9b2 CMake: Don't search for next Qt component if a required one is missing
If a project calls find_package(Qt6 COMPONENTS Gui Network) and Gui is
not found, there's no reason to look for Network, because the
COMPONENTS option implies that it is a required component. Failing to
find a component sets Qt6_FOUND to false, so we can break early.

If a project calls find_package(Qt6 OPTIONAL_COMPONENTS Gui Network)
then Network will still be looked for if Gui is not found.

6a2358e20f CMake: Remove custom Qt6 3rd party dependency implementation
Use _qt_internal_find_third_party_dependencies instead.
We rely on the inner find_dependency call to set the
Qt6_NOT_FOUND_MESSAGE message when a dependency is not found.
This implies removing the custom FATAL_ERROR handling
and relying on the parent find_package to display the
Qt6_NOT_FOUND_MESSAGE message.

We also clear Qt6_FIND_COMPONENTS if a dependency is not found.
No need to look for Qt packages if the Qt6 dependency was not met.
This reduces the amount of recursive error messages.
