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.

QDoc modifies its linking behavior depending on whether the -installdir
command line option was set or not; Without -installdir, QDoc will
use 'https://<url>' to link to targets loaded from external
documentation modules, instead of using relative paths.

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.

d470497d9a CMake: Make standalone tests TestsConfig file repo-target-set specific
Conan CI builds can built a qt repository in a repo-target-set
configuration. An example of that is qtscxml.

When building standalone tests, qt_build_tests includes a repo
specific TestsConfig.cmake file to call find_package on the modules
that were built as part of that repo.

That doesn't quite work with a repo-target-set build which is enabled
when the repo is built with a QT_BUILD_SINGLE_REPO_TARGET_SET value.

The TestsConfig.cmake file would be overridden with different contents
on each configuration.

Fix that by including the QT_BUILD_SINGLE_REPO_TARGET_SET value as
part of the TestsConfig.cmake file to be generated and included.

This means that when configuring the standalone tests, the same
QT_BUILD_SINGLE_REPO_TARGET_SET value should be passed, so that the
correct packages are found.

Add some debug statements to allow checking which TestsConfig.cmake
file is loaded when the standalone tests are configured with
--log-level=DEBUG.

c8dbb177f0 CMake: Allow opting out of building examples as ExternalProjects
We default to configuring examples as separate ExternalProjects when
using a developer / non-prefix Qt build.

This ensures we test that the examples configure successfully without
the pollution of the main Qt build (e.g. already found packages).

One down-side of this is that a developer's IDE doesn't see these
example targets, unless each project is loaded into the IDE
separately. This is cumbersome to do when refactoring or renaming
code across multiple example projects.

Allow configuring the example projects as part of the main Qt build
by setting QT_BUILD_EXAMPLES_AS_EXTERNAL to FALSE when configuring Qt.

Save the value of the variable in QtBuildInternalsExtra.cmake.in
so it's propagated to leaf repositories as well.

60f36007a3 CMake: Don't cache QT_SYNCQT across builds
There is no need for this variable to be stored in CMake's cache.  We
don't perform expensive operations to set up QT_SYNCQT, and we even
unset the cache variable to ensure it gets recomputed on
reconfiguration.

We still store QT_SYNCQT in a global property, because the function
qt_ensure_sync_qt is called in different directory scopes, and we want
to avoid re-calculations for every subdir.

It's now possible for the user to set QT_SYNCQT (see QTBUG-88088 for
motivation).  Also, in a non-prefix build, changes to syncqt.pl in the
source dir are reflected upon re-configuration in the build
tree (because qt_copy_or_install is called on every configure).

e1fe816d46 Implement generating of private cpp exports
Add the generating of private cpp exports for Qt modules.

Add the GENERATE_PRIVATE_CPP_EXPORTS option to qt_internal_add_module
that is the manual switch for private exports generator. Existing
modules in qtbase doesn't follow any strict convention of using
private cpp export. So there is no clue how to detect if generating of
the private exports is required or not for the module.

Use autogenerated private cpp exports in QtNetwork module.

CPP_EXPORT_HEADER_NAME argument of the qt_internal_add_module function
is replaced by the CPP_EXPORT_HEADER_BASE_NAME and has a different
meaning. The provided name is used as a base name for the private and
non-private headers that contains cpp exports. Header files suffixes
are constant: .h and _p.h for the non-private and private header files
accordingly.

3c1125d9fe CMake: Create plugin initializers for static user plugins
Previously we only created object library static plugin initializers
for Qt plugins only, not user-project plugins.

The reason was that if a user tried to install the plugin target via
an export set, CMake would error out saying that the _init library is
not part of the same export set.

Introduce an OUTPUT_TARGETS option that would allow projects to get
the name of the generated _init target, so they can install it if
needed.
This was already done for qt6_add_qml_module, so we just introduce the
same option for qt6_add_plugin.

Now user static plugins will have an _init target created, which will
be propagated to consumers whenever the consumers link against the
plugin itself.

We also need an internal option to disable this propagation, because
it's handled a bit differently for Qt plugins which can be linked
either via finalizers or via usage requirements.

Amends 91c65dd80c

As a result of the implementation change, cleanup example projects
to ensure that they build successfully (the important part is
specifying the CLASS_NAME).

Only plugandpaint works properly with both shared and static Qt
builds.

echoplugin works with a shared Qt build, but not a static one due to
some assumptions in the C++ code about shared plugins.

styleplugin doesn't seem to work properly neither with shared Qt
builds nor static Qt builds, at least on macOS. But it builds fine.
For some reason even if the plugin is found, the style is not applied.

Internally, we called

which was supposed to separate the arguments and write them into
config.opt.

However, passing arbitrary arguments after "-P script.cmake" only worked
by accident and is not supported.  As soon as arguments are passed that
are valid CMake arguments, like -help or -G, the CMake call would fail.

Now, we let configure.bat and qt-configure-module.bat write the
arguments as is into config.opt.in and let QtWriteArgsFile.cmake read
this file, separate the arguments and write config.opt.
