6ec21881dd CMake: Override simulator architecture to x86_64 for Xcode generator
The simulator build of Qt for iOS is currently x86_64 only, instead
of universal builds with an arm64 slice as well, since we don't
support xcframeworks. This means we can't rely on Xcode's default
simulator arch settings, which on an Apple Silicon Mac will be
arm64.

Instead we override the simulator arch, like we do for qmake.

effd6f63f1 CMake: Fix single standalone tests to use same Qt C++ language std
When using qt-cmake-standalone-test, we didn't tell CMake to use the
same C++ language standard that Qt used when it was configured.

We did tell CMake to do that when configuring tests with
qt-internal-configure-tests via the qt_build_tests macro.

To ensure the proper standard is set, we also need to
find_package(Qt6Core), because the std flag is derived from the
QT_FEATURE_cxxyz flag which is set by Core.

15117f84bb CMake: Relax constraint on not having feature values change
Previously if qtbase was built with feature A set to ON, then building
qtsvg, then rebuilding qtbase with feature A set to OFF, trying to
build qtsvg would fail with an error message at configure time saying
that the feature value has changed.

This check was added quite early in the Qt CMake port, presumably to
catch accidental reconfigures that might cause long rebuilds.

This has dubious benefit though. We constantly had people telling us
they get the error without knowing what to do. The usual advice was to
remove CMakeCache.txt and reconfigure.

Instead of forcing people to suffer this dance, relax the constraint
by issuing a warning instead of an error, and make it more clear why
a rebuild might happen (a changed feature value might change
the generated module C++ header file which in turn might be included
by various project sources).

ea8645d846 CMake: Deprecate _add_app/executable/test/tool PUBLIC_LIBRARIES option
Warn projects not to use it because PUBLIC_LIBRARIES don't make
sense for executable targets and it also led to some issues in the
internal functions where some of them did not expect to receive
PUBLIC_LIBRARIES.

To ensure builds don't needlessly break, treat PUBLIC_LIBRARIES values
as regular LIBRARIES. In the future we might add an error instead.

Using PUBLIC_LIBRARIES in qt_internal_add_app, etc, accidentally
worked because the option name and the values following it were
parsed as values of the "previous" option, like SOURCES or
INCLUDE_DIRECTORIES or LIBRARIES, and when those got
passed through to qt_internal_extend_target, things magically worked.

We have a lot of projects using PUBLIC_LIBRARIES, mostly due to the
way qmake pro files were written and how pro2cmake converted them.
We'll have to clean up each repo.

0e0352ab4d CMake: Fix install destination of in-tree examples
Previously we called _qt_internal_override_example_install_dir_to_dot
in Qt6CoreConfigExtras.cmake as part of a
find_package(Qt6 COMPONENTS Core) call, and we assumed that the
Extras file would always be included in each example project.

But our package dependencies handling code skips calling
find_package(Qt6Core) if Qt6Core_FOUND is already set to TRUE,
which will definitely happen due to root-scope find_package
calls when configuring other repos.
That means we wouldn't override INSTALL_EXAMPLEDIR to "."
and the install destination would end up being something like
${CMAKE_INSTALL_PREFIX}/example_relative_path/example_relative_path
aka a double nested path.

Make sure we call the
_qt_internal_override_example_install_dir_to_dot function
in Qt6ConfigConfig.cmake in addition to Qt6CoreConfig.cmake.

That way, even if Qt6Core is skipped during dependency resolution,
it's still handled by the Qt6 package itself.

Because the function is defined in the Core package, guard the call
with an if(COMMAND) and only call the function if it wasn't previously
called within the current or ancestor scopes.

578f4ba00c CMake: Add per-target support for iOS launch screens
To support per-target iOS launch screens we need a way to specify
custom Info.plist entries without using cache variables, which we were
forced to use due to the implicit configure_file done for
MACOSX_BUNDLE_INFO_PLIST.

We now introduce an extra configure_file call done in a finalizer,
before we hand off the Info.plist file to MACOSX_BUNDLE_INFO_PLIST.

This extra configure_file call allows us to insert / substitute
additional Info.plist entries that CMake does not allow setting.

If a custom Info.plist file is provided, the finalizer will simply
skip the logic for creating a new one.

dffcc2370e CMake: Record the precise package name where Private modules live
Previously if a target depended on CorePrivate, we would write a
_qt_internal_find_qt_dependencies(... Qt6CorePrivate) call into a
FooDependencies.cmake file.
That find_qt_deps call would remove the 'Private' suffix and would run
find_dependency with NAMES set to both the altered and non-altered
names.
This would find the relevant package but it would set the wrong
_FOUND variable name, e.g it would set Qt6CorePrivate_FOUND instead
of Qt6Core_FOUND.
This in turn could cause multiple lookups of the Qt6Core package
during dependency handling because the correct _FOUND var would not be
set.

Instead of always looking for the Qt6CorePrivate package, make sure
we look for an appropriately named package for all Privates modules,
because we have the necessary info to determine the correct name.

Note that INTERNAL modules will still be looked up via a Private
suffixed package name because that's how the package name is chosen
for them.

Remove the code that accounted for Private modules in
qt_internal_remove_qt_dependency_duplicates because it's not needed
anymore.

Warn when a package name can't be queried from a target's property
because the target might not exist yet.

Add a TODO comment for the code that searches with two NAMES.
We can't remove it right now, because it might break user projects
that use stale Dependencies.cmake files.

The dbus subdirectory is added before the tools subdirectory
to ensure that the new package name extraction does not error out, due
to trying to access a target that does not yet exist.

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.

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.

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.
