2148e1f0e6 wasm: increase default initial memory
Some apps may need more initial memory when linking, emscripten will
fail with:
wasm-ld: error: initial memory too small

This increases the default initial memory form 16MB to 20MB.

Larger apps might still get this error, in which case
QT_WASM_INITIAL_MEMORY can be set.

6d039a5e76 wasm: enable event dispatcher asyncify support
Misc. fixes, including:

Fix a couple of typos in the JavaScript code. Also, macros-
within-macros don’t work, (without resorting to preprocessor
token pasting), so remove the debug output for now.

Limit the exec() “simulateInfiniteLoop” workaround to
top-level application exec() only. This way, asyncify
can be used for nested QEventLoop::exec() calls. (Emscripten
supports one level of suspend only, so we don’t want
to use that for the top-level exec(), but instead use it
for dialogs and such).

Use the new QEventLoop::ProcessEventsFlag::ApplicationExec
enum value to detect the exec() call type.

63acb0d9fe Move qt_finalize_framework_headers_copy to the scope finalizer
The qt_finalize_framework_headers_copy function uses the module
QT_COPIED_FRAMEWORK_HEADERS property to generate the dependency list
for the ${target}_framework_headers target. In a common case elements
can be added to the QT_COPIED_FRAMEWORK_HEADERS property after the
qt_internal_add_module command call, that's why we need to make sure
that qt_finalize_framework_headers_copy is called after collecting all
headers assigned to the module.

f04dbdfc97 CMake: Don't create targets if dependencies are not found
If one of the dependencies in QtFooModuleDependencies.cmake is not
found, QtFoo_FOUND will be set to False by find_dependency.

In that case, we should not create imported targets that belong to
that package.
It would be misleading for projects that do target existence checks
instead of package_FOUND checks as well as generally being
incorrect. The created imported targets might be referencing other
targets that would not exist.

b04a0f0c04 CMake: Allow enabling/disabling QT_HOST_PATH checks via variable
One can now pass -DQT_REQUIRE_HOST_PATH_CHECK=OFF or
-DQT_REQUIRE_HOST_PATH_CHECK=ON to force disable or enable
the QT_HOST_PATH and QT_HOST_CMAKE_DIR_PATH validity checks.

One potential use case is if a project wants to manually find
QtFooTools packages by manipulating CMAKE_FIND_ROOT_PATH and such,
in which case they might not want to pass a QT_HOST_PATH.

Another potential use case is cross-building Qt with
-DQT_BUILD_TOOLS_WHEN_CROSSCOMPILING=ON and allowing the same
generated toolchain file to be used on the device image.

By default the generated toolchain file would require a host path
because it expects that it's still being used for cross-compiling.
But once the toolchain file is deployed to the device there's no need
to use the host tools anymore.

Another use case is building a desktop Qt using the host tools of
another desktop Qt. The new desktop Qt can use its newly built tools
just fine and wouldn't need the original desktop Qt tools.

QT_REQUIRE_HOST_PATH_CHECK needs to be added the list of vars to pass
through to try_compile calls.

f917df2752 CMake: Fix _QT_TOOLCHAIN_VARS_INITIALIZED check in toolchain file
The environment variable check to set extra env vars
was using invalid syntax. The condition always resolved to TRUE
which means the env vars were constantly re-assigned inside each
try_compile project.

To check for undefined-ness, one can use if(NOT DEFINED ENV{...})
To check for false-ness, one can use if(NOT "$ENV{...}")
To check for string emptiness, one can use
  if(NOT "$ENV{...}" STREQUAL "")

In this particular case checking for false-ness is good enough.
The extra re-assigning had no visible effect, so this is just cleanup.

As a drive-by, clarify one comment.

102c1cff72 CMake: Clean up and improve QT_HOST_PATH_CMAKE_DIR computation
Previously when one wanted to use a cross-compiled Qt with a host Qt
installed in a non-default location, they'd have to provide both
QT_HOST_PATH and QT_HOST_PATH_CMAKE_DIR.

This change will now try to first check if ${QT_HOST_PATH}/lib/cmake
is a valid path on disk and use that. This is nicer to the user
because they don't need to specify 2 paths anymore.

Furthermore the path computation and sanity checks are now done after
any extra toolchain cmake files are loaded, to give an opportunity
to the files to set the paths first.

Finally, both variables need to be added to
__qt_toolchain_used_variables so they are passed along to try_compile
calls if the variables are specified manually.
Otherwise when the toolchain file is loaded by a try_compile project,
it will error out saying no host path found (as long as the initial
paths embedded in the toolchain are invalid).

9ed274a48d CMake: Enforce lookup of host Tools packages in qt_internal_add_tool
When cross-building, qt_internal_add_tool would accidentally find device
QtFooTools CMake packages as a result of calling find_package. It should
have found host Tools packages instead.

The reason was due to a combination of setting
CMAKE_FIND_ROOT_PATH_MODE_PACKAGE to BOTH, find_package preferring
the lookup of packages in CMAKE_FIND_ROOT_PATH before CMAKE_PREFIX_PATH
and there being a Tools package in the device sysroot.

Because qt_internal_add_tool didn't adjust CMAKE_FIND_ROOT_PATH to
contain the host path, the device package was picked up.

Change the implementation not to set CMAKE_FIND_ROOT_PATH_MODE_PACKAGE
and instead modify both CMAKE_FIND_ROOT_PATH and CMAKE_PREFIX_PATH
to prefer the host packages instead.

This aligns to the behavior that was introduced in
ec90f9013b
which is used in QtModuleDependencies when looking for Tools packages.

5ffc744b79 CMake: Allow disabling package version check
When building Qt repos, all find_package(Qt6) calls request a
PROJECT_VERSION version which is set in .cmake.conf via
QT_REPO_MODULE_VERSION.

This means trying to configure qtsvg from a 6.3 branch using a
6.2 qtbase won't work, because qtsvg will call find_package(Qt6 6.3)
and no such Qt6 package version exists.

There are certain scenarios where it might be useful to try to do
that though.
One of them is doing Qt development while locally mixing branches.
Another is building a 6.4 QtWebEngine against a 6.2 Qt.

Allow to opt out of the version check by configuring each Qt repo
with -DQT_NO_PACKAGE_VERSION_CHECK=TRUE. This setting is not
recorded and will have to be set again when configuring another
repo.

The version check will also be disabled by default when configuring
with the -developer-build feature. This will be recorded and embedded
into each ConfigVersion file.

If the version check is disabled, a warning will be shown mentioning
the incompatible version of a package that was found but that package
will still be accepted.
The warning will show both when building Qt or using Qt in a user
project.
The warnings can be disabled by passing
-DQT_NO_PACKAGE_VERSION_INCOMPATIBLE_WARNING=TRUE

Furthermore when building a Qt repo, another warning will show when an
incompatible package version is detected, to suggest to the Qt builder
whether they want to use the incompatible version by disabling the
version check.

Note that there are no compatibility promises when using mixed
non-matching versions. Things might not work. These options are only
provided for convenience and their users know what they are doing.

87215c70c0 CMake: Fix rpath-link dependencies when cross-compiling
Private Qt module dependencies of a Qt module are recorded
in the IMPORTED_LINK_DEPENDENT_LIBRARIES property of a Qt module.
This property is used to compute the runtime dependency dir path
to be passed to the linker via the -rpath-link option.

If the referenced target does not exist in the scope where it's
used, no -rpath-link will be generated (or at least that specific
dir path won't be passed).
The linking operation will either fail saying the library is not found,
or a different version of the library might be silently picked up in
the sysroot or other implicit lib dir.

Make sure that QtFooModuleDependencies.cmake calls find_package() for
all Qt module private dependencies (or other Qt provided 3rd party
libs in the Qt6:: namespace) so that the targets are in scope and
IMPORTED_LINK_DEPENDENT_LIBRARIES does its job.

qmake also records the INTERFACE_LINK_LIBRARIES of a private Qt module
as the runtime dependencies of the module.
It's not clear why it does that. A private Qt module is an
INTERFACE_LIBRARY so it shouldn't add any new runtime dependencies.

Nevertheless, the find_package part of that has been recently addressed
in 2b6500cd15 for a different reason.

This change is basically the CMake equivalent of
326b91ea78

b6cbd9c43a QList: deprecate iterator<->pointer implicit conversions (2/3)
The constructor from a raw pointer should be
1) constexpr,
2) explicit, and
3) *private*.

We can do 1) without too much trouble.

2) is a (easy to fix) SIC in case of implicit conversions accidentally
relied upon from somewhere.

3) cannot be "easily" fixed by user code (they have to refactor), and
also, it's a BIC on Windows which encodes class members' access in
symbols. Someone may have been exporting some QList subclass, in turn
exporting the iterator classes, and therefore that someone now has the
constructors' symbols with a given access.

So, don't do 2+3 _just yet_ for user code, but set a deadline: Qt 6.5 is
the last that will support this. On Qt 6.6, we switch. All of this on
non-Windows, againt to avoid an ABI break. One can opt-in at any time
via a suitable define.

Given we have this define, use it to guard the other way around as well:
conversions from an iterator to a raw pointer should never be explicit
(there's std::to_address for this).

[ChangeLog][QtCore][QList] Converting a QList's iterator from and to a
raw pointer is deprecated, and will get removed in Qt 6.6. User code can
prepare for the change by defining QT_STRICT_QLIST_ITERATORS.

aad4158959 CMake: Postpone target existence check for qml plugin targets
Each included qml Qt6FooPluginTargets.cmake file checks whether
all the dependency targets that are referenced in the file already
exist by the time the file is included.

If one of the referenced targets is missing, the file sets
${CMAKE_FIND_PACKAGE_NAME}_NOT_FOUND_MESSAGE with a message mentioning
which targets are missing and also sets
${CMAKE_FIND_PACKAGE_NAME}_FOUND to FALSE.

All our qml package Config.cmake and Targets.cmake files are
include()d by Qt6QmlPlugins.cmake using a file(GLOB) which means the
order in which the files are loaded is implementation-defined.

Furthermore we didn't check the above set variables after each
inclusion, which means the values are overridden and the last plugin
to be loaded determines whether the Qml package is found or not.
If the last included file sets no error, it effectively silences any
previously set error.

Ever since we added dependencies between the qml plugin targets
themselves, we hit the above situation and depending on the platform,
no error was shown because the last file overrode any errors.

But we finally got a specific platform (wasm) which unearthed the
problem (QTBUG-97478). This can happen for any static Qt build though.

To fix this properly, we will most likely have to rewrite the whole
inclusion mechanism to use find_package() so that dependencies
can be resolved recursively as needed. This is a non-trivial change
that will have to be addressed in both qtbase and qtdeclarative.

In the mean time, a stop-gap solution that this change implements is
to include all the files while ignoring any error messages.
Then include the files one more time and check for error message after
each included file.

All qml plugin targets should have been brought into scope with the
first round of inclusions, thus circumventing "missing referenced
target" errors, while still catching any other possible errors.

cb0ea39895 CMake: remove support for building Qt with the old Intel compiler
This hasn't worked for some time. It's not in our CI and I don't think
it was working at all. When I tried to build it, I ran into several
problems with C++17 and an Internal Compiler Error I did not have any
interest in working around.

After discussing with the Intel compiler team, it was decided that
fixing those issues in the old compiler is not going to happen. Instead,
their recommendation is to adopt the new LLVM-based compiler, which
the last commit added support for.

This commit does not remove qmake support for the old ICC. It's possible
someone is using qmake with a non-Qt6 project and ICC.

326b91ea78 Fix missing QT.<module>.run_depends entries in module .pri files
The .pri files for public Qt modules were missing run_depends entries.
Those entries are used by qmake when linking plugins of a static Qt
build.  In shared builds, run_depends entries are used to decide whether
to add the -rpath-link argument to the linker.  In that matter,
run_depends entries serve a similar purpose as CMake's
IMPORTED_LINK_DEPENDENT_LIBRARIES.

In Qt5, run_depends entries consist of the qmake values QT_PRIVATE and
QT_FOR_PRIVATE.

QT_PRIVATE contains the Qt modules that are privately linked to the
public module, and QT_FOR_PRIVATE are the dependencies of the private
module.  That loosely translates to LINK_LIBRARIES of the public module
and INTERFACE_LINK_LIBRARIES of the private module.

Private modules whose public counterparts are already public
dependencies don't have to be added to run_depends.

f19668ce65 Don't use libs in /usr/local for configure tests by default on macOS
Since commit f3c7d22dd0 we do not use
libraries from /usr/local and other non-system locations on macOS.  But
our configure tests still did.  This led to discrepancies between
find_package calls in configure tests and the Qt project itself.

Mentioned commit removed /usr/local and friends from
CMAKE_SYSTEM_PREFIX_PATH.  But we can't pass this variable to the
configure tests, because CMake sets it up and overwrites our value.

Pass CMAKE_SYSTEM_PREFIX_PATH and CMAKE_SYSTEM_FRAMEWORK_PATH as
QT_CONFIGURE_TEST_CMAKE_SYSTEM_{PREFIX|FRAMEWORK}_PATH variables to
tests.

Tests with separate project files that call find_package() must add code
like this after the project() command:

if(DEFINED QT_CONFIGURE_TEST_CMAKE_SYSTEM_PREFIX_PATH)
    set(CMAKE_SYSTEM_PREFIX_PATH
        "${QT_CONFIGURE_TEST_CMAKE_SYSTEM_PREFIX_PATH}")
endif()
if(DEFINED QT_CONFIGURE_TEST_CMAKE_SYSTEM_FRAMEWORK_PATH)
    set(CMAKE_SYSTEM_FRAMEWORK_PATH
        "${QT_CONFIGURE_TEST_CMAKE_SYSTEM_FRAMEWORK_PATH}")
endif()

Adjust pro2cmake accordingly.

165e01d5d5 CMake: Ensure that UNIX is set for INTEGRITY
Certain platform-related variables, in this case UNIX, must be set in a
platform module, because they get cleared after the toolchain file is
loaded.  Such platform modules live in upstream CMake, but there is none
yet for INTEGRITY.  This manifests in an undefined UNIX variable and
"System is unknown to CMake" warnings for the project and every
configure test.

Add the CMake module "Platform/Integrity" in the cmake/platforms
directory.  Add this directory to CMAKE_MODULE_PATH to let CMake load
Platform/Integrity when the toolchain file set CMAKE_SYSTEM_NAME to
"Integrity".

CMake's module directory takes precedence, when loading platform
modules.  This is special for platform modules and different from the
documented behavior of CMAKE_MODULE_PATH and include().

In case the user wants to provide their own platform modules via
CMAKE_MODULE_PATH, they can instruct Qt to not add its path by setting
QT_AVOID_CUSTOM_PLATFORM_MODULES to ON.

Make sure that configure tests with project files also load the custom
platform module.

99899dd299 Revert "CMake: Warn if cmake_minimum_required has an unsupported low version"
This reverts commit 657525965b.

The change relied on reading the last value of the
CMAKE_MINIMUM_REQUIRED_VERSION variable before one of the Qt packages
is found to use it for the version check.

Even if a user project has a cmake_minimum_required() right at
the beginning of the project with a supported version specified,
the first project() call which loads a CMake toolchain file could
contain another cmake_minimum_required() call with a lower
(unsupported) version and that version would be used for the check,
failing the project configuration.

The Android NDK ships such a toolchain file, which requires version
'3.6'.

Thus, relying on the last value of CMAKE_MINIMUM_REQUIRED_VERSION is
not robust enough.

657525965b CMake: Warn if cmake_minimum_required has an unsupported low version
Qt6Config.cmake calls cmake_minimum_required to ensure a recent enough
CMake version is used in projects.

That call does not set policies in the calling subdirectory scope,
because find_package introduces a new policy scope.

If a project using Qt has a 'cmake_minimum_required(VERSION 3.1)'
call and is configured with a recent CMake, many policies will
still be set to OLD.

One such policy is CMP0071 (Run AUTOMOC on GENERATED files). The
policy value is queried at generation time rather than at target
definition time, which means we can't influence the policy value
(e.g. inside the implementation of qt_add_executable for example)

The inability to influence the policy value for targets created by our
own CMake functions is unfortunate and can lead to issues (in the case
of the above policy to compilation / linker issues).

Record the version of the last cmake_minimum_required call before
the Qt packages are found and error out if the version is lower than
the minimum supported one.

A project can reduce the error into a warning by specifying a
-DQT_FORCE_MIN_CMAKE_VERSION_FOR_USING_QT_IN_CMAKE_MIN_REQUIRED=3.xyz
option when configuring the project.
If the option is used and build issues arise, no official support is
given.

All the CMake example projects shipped with Qt specify a minimum
version of 3.16 already (which is the minimum for shared Qt builds),
so it shouldn't be an issue to require that in other user projects as
well.

Implementation wise, we follow the existing pattern to record
what the minimum and computed versions for static and shared Qt
builds are at qtbase configure time.
These are then checked before the Qt6 or QtFoo packages are
find_package'd.

Drop the -installdir if QT_BUILD_ONLINE_DOCS was set. This behavior matches
the 'build_online_docs' scope that was used for qmake documentation
targets, and is useful for documentation projects that are not part of
Qt but want to link to Qt docs simply by loading the index files of Qt's
modules.

5d840f0f7a CMake: Get toolchain file path from EMSDK env for Wasm user projects
Try to to chainload the emscripten CMake toolchain file from the
EMSDK env var if it is set, instead of requiring the user to explicitly
specify a path to the file via QT_CHAINLOAD_TOOLCHAIN_FILE.

The order in which the toolchain file is chainloaded becomes is as
follows:

1) The initial toolchain file path that was specified when configuring
   qtbase is set written as the initial value of
   __qt_chainload_toolchain_file in qt.toolchain.cmake
2) If EMSDK env var is set, it overrides the value from 1)
3) If QT_CHAINLOAD_TOOLCHAIN_FILE cache var is supplied it overrides
   the value from 2)

Whichever value ends up in __qt_chainload_toolchain_file is
checked too see if the file exists.
If it exists it gets included, if it doesn't, a warning is issued.

This checking logic is a bit crude and should be improved and unified
with the Android chainload checking, but the current change already
improves the behavior for users of Qt.
