4cef4f1c1b Make configure -no-pkg-config actually work
Turning off pkg-config with the configure flag -no-pkg-config did not
work.  There are different defaults for FEATURE_pkg_config on different
platforms (e.g. Linux: ON, Windows: OFF).  The existing code that
calculated the initial FEATURE_pkg_config value assumed that the default
is OFF and never turned the feature off.

f3483e6b96 CMake: Allow no install + custom on-device prefix for desktop builds
Allow such a combination
- staging prefix (CMAKE_STAGING_PREFIX / -extprefix) set to the
  qtbase build dir
- install prefix (CMAKE_INSTALL_PREFIX / -prefix / on-device prefix) set
  to some custom location
even for non-cross builds.

An example would be
    configure -prefix    /usr \
              -extprefix ~/qt/qtbase_build_dir

CMake will put the Qt libraries in the qtbase build dir, ninja install
will not be required, but ultimately in order to run applications,
the Qt libraries are expected to be in /usr.

Support for this scenario was originally added for cross-builds in
062318feb2 , but not desktop builds.

Such a build is useful when you want to have install rpaths different
from where Qt is initially installed to (the staging prefix).

This case doesn't really happen often when targeting desktop
platforms, it's mostly used for cross-compilation (e.g yocto).

Being able to have the same setup with a desktop build is nevertheless
useful for faster iteration on build system issues in such a scenario.

9a18facc66 CMake: Allow specifying custom install dir for non-EP examples
Originally, QT_INTERNAL_EXAMPLES_INSTALL_PREFIX was added to
control the installation of examples when they are built as
ExternalProjects, and was not considered for the non-EP case because
we hoped to switch entirely to EP-based building.

Due to some unsolved issues regarding using EP builds in CI, add the
ability to control the installation of non-EP examples.

This will be used in the CI to allow removing the hacky
INSTALL_EXAMPLEDIR and INSTALL_EXAMPLESDIR assignments in example
projects.

It is also likely that we will not deprecate the non-EP based
building, because it is useful for IDE integration (EP targets
are not as developer-friendly to work with in an IDE in regards
to rebuilding).

939a8281e6 CMake: Fix picking of the binary_for_strip project location
Fix binary_for_strip project not being found when the following
conditions were met:
- building a repo other than qtbase
- qtbase sources are not available on the machine
(usually happens in CI where only the current repo sources are
available).

The issue was that QT_CMAKE_DIR would always be defined, regardless of
which repo was being built and the system would incorrectly assume
the location of the project files.

The fix is to always pick up the sources from qtbase's source dir if
they are available (this time done with an appropriate check),
otherwise use the installed files.

Note that the behavior of always using the qtbase sources if available
is not exactly the best, but it is a more general issue that affects
other code too.
In the name of consistency, make it so for the binary_for_strip
project as well, but add TODOs in code to address the situation
in a separate change.

39f657032b CMake: Generate and use a wrapper script for stripping binaries
MinGW 11.2.0 comes with a strip.exe that strips the ".gnu_debuglink"
section in binaries, a section that is needed for the separate debug
information feature.

binutils version 2.34 mentions the feature for the first time:
https://sourceware.org/binutils/docs-2.34/binutils/strip.html#strip

To ensure the debuglink section is preserved, generate a shell wrapper
that calls the original strip binary with an extra option to keep the
required section.

To determine if the option is supported, we build a real shared library
on which strip will be called with the --keep-section option.
If the option is not supported, a wrapper is not generated and the
stock strip binary is used.

This logic only applies when targeting Linux and MinGW + a shared
library Qt. For other targets, the stock strip binary is used.

Developers can opt out of this logic by passing
-DQT_NO_STRIP_WRAPPER=TRUE when configuring each Qt repo.

c89da21249 CMake: Fix cross-building examples in prefix builds as ExternalProjects
For examples to successfully find not yet installed Config files in a
prefix cross-build, both CMAKE_FIND_ROOT_PATH and CMAKE_PREFIX_PATH
need to be adjusted when toolchain files set
CMAKE_FIND_ROOT_PATH_MODE_PACKAGE to ONLY.

Before this change, we lacked two things.

1) If the chain-loaded toolchain file sets CMAKE_FIND_ROOT_PATH
(instead of appending), then the initial value of CMAKE_FIND_ROOT_PATH
that was passed by ExternalProject's initial cache would be
overridden.

2) The prefixes we passed via QT_EXAMPLES_CMAKE_PREFIX_PATH did not
end in lib/cmake, to work around the path re-rooting problem in CMake.

We can handle both of these points by using
QT_ADDITIONAL_PACKAGES_PREFIX_PATH which was introduced for Conan
usage.

Each value assigned to QT_ADDITIONAL_PACKAGES_PREFIX_PATH
gets prepended to CMAKE_FIND_ROOT_PATH by qt.toolchain.cmake AFTER the
original toolchain file is chain-loaded.

And each value also gets lib/cmake appended and assigned to
both CMAKE_PREFIX_PATH and _qt_additional_packages_prefix_paths (used
by Qt6Config.cmake.in to work with find_package + NO_DEFAULT_PATH).

This is exactly what we need to ensure examples build.

98c89c8cc1 CMake: Build examples as ExternalProjects in prefix builds
Change prefix builds to use ExternalProjects to build examples
by default. This will affect our CI which only does prefix builds.

To make it work, we have to do a few adjustments:
- look for Config files in the build-tree (before Qt is installed)
- build only one examples with only a single config,
   even if Qt is a multi-config build
- install examples as part of main make install step, rather than
  as part of the make step (which is the default for EPs)
- adjust CXX flags when building with MSVC to ensure we can still
  use sccache and separate debug info
- derive the correct install prefix for each example and pass it
  to the ExternalProject

As a drive-by, add TODOs to address tidiness of the code and corner
cases that likely don't work (Conan).

ac4a913f33 CMake: Deduce install prefix of example in qt_internal_add_example
We want to get rid of the INSTALL_EXAMPLEDIR and INSTALL_EXAMPLESDIR
code in each example project.

This was an internal workaround to ensure examples are installed into
a relative path somewhere under $qt_prefix/examples and not in
$qt_prefix/bin or similar.

To achieve that we do two things.

First, deduce the install prefix for each example in the
implementation of qt_internal_add_example (our add_subdirectory
wrapper) and assign it to CMAKE_INSTALL_PREFIX before calling
add_subdirectory. We need to make sure to remove the default
value of CMAKE_INSTALL_PREFIX in the generated
cmake_install.cmake file.

Second, we set an internal variable called
QT_INTERNAL_SET_EXAMPLE_INSTALL_DIR_TO_DOT before the add_subdirectory
call, which will be checked whenever find_package(Qt6Core) is called
in an example project. If the variable is set, the
INSTALL_EXAMPLEDIR var is set to "." in the scope of where Qt6Core
is found.

This ensures that the hardcoded INSTALL_EXAMPLEDIR values in our
example projects are changed to ".".

With both changes, our example project install(TARGET DESTINATION)
calls will now install to
"${CMAKE_INSTALL_PREFIX}/examples/${example_relative_dir}/."

Once all repositories are updated to use qt_internal_add_example
instead of add_subdirectory, we can get rid of the
QT_INTERNAL_SET_EXAMPLE_INSTALL_DIR_TO_DOT workaround.

For repositories that still don't use qt_internal_add_example,
the install prefix rewriting will not happen, but the examples will
still be installed to the proper place because they use their own
hardcoded INSTALL_EXAMPLEDIR value.

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.

42970e490a CMake: Bump min required CMake version for shared Qt builds to 3.16
Building a shared library Qt configuration already required a minimum
CMake version of 3.16, because we depend on CMake's Autogen.json files
which are used for metatype.json file generation.

If a lower version was used, a FATAL_ERROR was issued in
qt6_extract_metatypes.

This change is essentially moving the check to happen earlier in the
qtbase configure process.

User projects will now /also/ officially require a minimum of 3.16
(up from 3.14).

As a consequence, the min/max version policy range that is set in
the public QtFooConfig.cmake files is changed
from 3.14..3.19
to   3.16..3.20

The upper bound is raised because building and using Qt works fine
with all CMake 3.20 policies set to NEW.

[ChangeLog][CMake] Building Qt as shared libraries now requires
CMake version 3.16 or later. Building user projects with CMake using
that Qt installation also requires a CMake version of 3.16 or later.

e80b010795 Use target_link_options to propagate object libraries
target_link_options are placed by CMake at the beginning of a linker
line. This gives us an opportunity to use the function to propagate
object libraries. This change adds one more check in the root
Config.cmake file. If CMP0099 policy is enabled, CMake enables
propagating of the linking options when linking two static libraries
using the PRIVATE linking visibility, so we can rely on the correct
linking order and expect object libraries to be propagated.

Note that on the platforms where cmake version is higher than 3.16
Qt uses CMP0099 NEW in functions like qt_add_executable. This means
that at the moment of creating an executable target the TARGET_POLICY
genex will also be NEW, so we do not take into the account the user
defined CMP0099.

If the CMP0099 policy is not available for a certain CMake version
we skip the TARGET_POLICY check and simply disable propagation of
the object libraries using target_link_options for both user and Qt
libraries. This is applicable for the CMake versions 3.16 and less.

Linking approaches have the following priorities(from higher to lower)
after this change:
  - target_link_libraries - works if link order matters not or CMake
    version greater equal 3.21.
  - target_link_options - works if CMP0099 is set to NEW by user or
    if the CMake version is greater than or equal to 3.17 and an
    executable is created using Qt functions.
  - object library finalizer - works if CMake version is greater equal
    3.19 or qt6_finalize_target is called explicitly.
  - target_sources - is used when all the other approaches could not
    be used.

5fb99e3860 Check the impact of static link order for user projects
For user projects we run the static link order check once
'find_package(Qt6 ...)' is called.

If linker can resolve circular dependencies between static libraries
and object files we set the _qt_link_order_matters property of the
Qt::Platform target. This indicates the use of finalizers is not
required and we may rely on CMake-base propagation of resource
libraries and resource object files.

If linker could not resolve circular dependencies depending on
the _qt_resource_objects_finalizer_mode value:
  - Finalizer will be called and collected resource objects will be
    linked to the target directly.
  - Finalizer will be omitted and resource objects will be linked
    using the target_sources function implicitly. This only
    propagates resource one level up if consumer links the static
    library PUBLICly, but all symbols will be resolved correctly
    since object files are placed in the beginning of the linker line.

In the CMake version 3.21 we expect that CMake will take care about
the order of the resource object files in a linker line, it's
expected that all object files are located at the beginning of the
linker line.

TODO: Need to confirm that the CMake 3.21 meets the expectations.

d97fd7af2b Build examples in isolated sub-builds using ExternalProject
Examples are intended to show how to build against an installed Qt.
Building them as part of the main build means the way the Qt targets
are defined and created are not representative of an end user's build.
By building them as separate projects using ExternalProject, we can
more closely replicate the intended audience's environment. This
should allow us to catch more problems earlier.

Having examples built as part of the main build also creates problems
with some static builds where a tool built by the main build is needed
during configure time. This happens with other repos like qtdeclarative
but not (currently) with qtbase. Converting the examples in qtbase to
be built using ExternalProject is intended as a demonstrator for how
other repos can do similar. Until other repos are converted, they will
continue to work as they did before, with examples as part of the main
build for non-static builds only.

The new build-externally behavior is only supported for non-prefix
builds with this change. Prefix builds will continue to use the old
non-external method. Support for building examples externally in
prefix builds will be a separate change.

4b09522c23 Add support for building and installing repo target sets

targets within a Qt module repository.

In a Qt repository, a repo target set 'qtfoo' can be defined in the
top-level project file with
    qt_internal_define_repo_target_set(qtfoo DEPENDS Bar Baz)

The DEPENDS argument specifies Qt components that need to be
find_package'd when building the targets that belong to qtfoo.

In subdirectory project files, use
qt_internal_include_in_repo_target_set(qtfoo) to mark the file as
belonging to the repo target set.

To build and install a single repo target set, specify
QT_BUILD_SINGLE_REPO_TARGET_SET=qtfoo when configuring the Qt
repository.

98e8180e56 Fix error when re-configuring an already installed Qt repository
When building and installing a Qt repo that provides plugins for a Qt
module within a different repository (for example, qtimageformats
providing imageformat plugins for QtGui), re-configuring that repository
would result in configuration errors like

"add_library cannot create ALIAS target "Qt6::QTgaPlugin" because
another target with the same name already exists."

This happened, because the find_package(Qt6 COMPONENTS Gui) calls pulled
in the Qt6*PluginConfig.cmake files that create imported targets for the
plugins we want to build.

To fix this, when building Qt, we now load only plugins that are
provided by repositories the currently building repository depends on.

We read the repo dependencies from dependencies.yaml when the
Qt6BuildInternals package is loaded, but only in static builds and only
if we're currently building a Qt repository.

To find out whether we're building a Qt repository, we check whether
QT_REPO_MODULE_VERSION is defined. We cannot check QT_BUILDING_QT,
because that variable is not available for the first find_package calls
in the repository's top-level project file.

In each Qt6*PluginConfig.cmake file, we bail out if the plugin's
repository is not one of the ones in QT_REPO_DEPENDENCIES.
