In Qt 5 times, if Qt was configured with -make examples, running
make install would not only build and install the example binaries,
but would also install the example sources into the prefix.
Installation of example sources was not implemented when the Qt 6
build system has switched to using CMake.
There is still a use case for it though, mainly for Qt Creator, which
only shows the examples of a Qt kit if the sources are available.
In contrast to Qt 5, in Qt 6 we will not install example sources
by default. It will be opt in.
To enable installation of examples sources, configure with
configure -make examples -install-examples-sources
or
cmake -DQT_BUILD_EXAMPLES=ON -DQT_INSTALL_EXAMPLES_SOURCES=ON
The -make examples part is required, otherwise
-install-examples-sources has no effect.
All example sources can be installed by calling
cmake --install . --component examples_sources
in the qt repo build directory.
In a top-level build, per-repo installation can be done using
cmake --install . --component examples_sources_<repo_name>
where repo_name could be 'qtbase'.
A single example's source can be installed by calling
cmake --install . --component examples_sources_<subdir_name>
where subdir_name is the subdirectory name of the example, e.g.
'gallery'.
Implement installation of example sources by hooking into the
qt_internal_add_example command.
This means that all examples in all repos need to be added via
qt_internal_add_example instead of add_subdirectory, to ensure the
sources are installed. The majority of repos already use it.
For testing purposes one can configure with
-DQT_BUILD_EXAMPLES=ON -DQT_INSTALL_EXAMPLES_SOURCES=ON
-DQT_INTERNAL_NO_CONFIGURE_EXAMPLES=ON to allow testing installation
of examples sources without building them.
Take into account an additional variable called
QT_INTERNAL_EXAMPLES_SOURCES_INSTALL_PREFIX to allow installation of
example sources into a location different from the example binaries.
As a cleanup, the NAME option that could previously be passed to
qt_internal_add_example_external_project has been removed.
That's because it's never used anywhere and could not have worked
anyway because qt_internal_add_example_in_tree never handled it.

A regression was introduced in
48841c34d2
when configuring qtshadertools with -prefix -debug and
no -developer-build.
qtbase would have been built as Debug, but qtshadertools as release.
This caused qsb.exe to link to a debug c++ runtime via QtCore, and a
release one via QtShaderTools libraries and thus cause heap corruption
crashes during runtime due to the mismatch.
This happened because the check in cmake/QtSetup.cmake thought Debug
was the default build type (nothing was specified on the command line)
without knowing it was explicitly set BuildInternals.
Set a variable when BuildInternals sets CMAKE_BUILD_TYPE and make
sure QtSetup does not override it then.

The syncqt tool was originally designed to run at build time, as a
part of dependency chain of Qt modules. This works well unless we need
the code model of the Qt project in IDE, since Qt source code actively
uses header aliases, and creating them at build time breaks the code
model until the initial build is done. So we made syncqt the configure
time tool to not break the developer experience.
It's more likely that developers build Qt using command line or don't
need the code model before the first build. So running the tool at
configure time should be optional.
QT_SYNC_HEADERS_AT_CONFIGURE_TIME switches the "mode" of the syncqt
tool from build time tool to the configure time tool. Without the
option enabled build procedure runs all the syncing targets at build
time only. The exception are the developer builds, if the
'-developer-build' option is enabled, QT_SYNC_HEADERS_AT_CONFIGURE_TIME
is set to TRUE by default. This gives better development experience for
the developers that don't use the code model in their IDE or don't
require it before the first build is finished. Also this build time
mode is preferred for the CI or similar build procedures where code
model is not required at all.
By default, the option initialized from the
QT_INTERNAL_CONFIGURE_FROM_IDE CMake variable.
TODO: The option is forced to TRUE for the static Ninja Multi-Config
builds. See QTBUG-113974 for details.

Before this change, we had the following behaviors.
On platforms other than Windows-MSVC:
- when no build type was specified, we defaulted to Release
- when -developer-build was specified, we defaulted to Debug
- regardless of platform, unless the option was explicitly specified,
we never defaulted to -debug-and-release.
On Windows-MSVC, we always defaulted to Debug. Which is inconsistent
with the rules above.
The difference happens because CMake always sets CMAKE_BUILD_TYPE to
Debug during the first project() call when targeting the Windows-MSVC
platform.
We interpreted that as the user setting the build type, and thus we
didn't want to override what the user specified.
After this change, if we detect that it's cmake setting the build
type, we assign a build type that follows the non-Windows-MSVC rules.
This change unifies the behavior across all platforms.

An approach of test batching (joining multiple tests into a single
binary) has been taken, due to long linking times/binary size on certain
platforms, including WASM. This change adds a new feature
'batch_test_support' in Qt testlib. Based on the value of the feature,
test batching may become enabled with the -batch-tests switch.
Batching works for every target added via qt_internal_add_test. When
first such target is being processed, a new combined target for all of
the future test sources is created under the name of 'test_batch'.
CMake attempts to merge the parameters of each of the tests, and some
basic checks are run for parameter differences that are impossible to
reconcile.
On the C++ level, convenience macros instantiating the tests are
redefined when batch_tests is on. The new, changed behavior triggered
by the changes in the macros registers the tests in a central test
registry, where they are available for execution based solely on their
test name. The test name is interoperable with the names CMake is aware
of, so CTest is able to run the tests one by one in the combined binary.

This is quite confusing behavior, in more than one way.

Previously it was possible to achieve the same by specifying

In non-prefix builds, we want to prevent users from accidentally running
"cmake --install". We did that by replacing cmake_install.cmake with an
empty file.
The responsible target remove_cmake_install is visible in IDEs, appears
in the build output, and the approach is hacky.
It's cleaner and easier to add bail out code at the top of
cmake_install.cmake. This is now done when calling qt_build_repo_begin.
As a bonus, print an informative message on installation.

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.

Before, we would just issue a warning which is likely to get overlooked
in CMake's output. Also, the configure summary would report "Using
ccache ... yes" but CMAKE_<LANG>_COMPILER_LAUNCHER stays unset, which is
inconsistent.
Make QT_USE_CCACHE=ON and missing ccache a hard error.

Change the default installation prefix to C:/Qt/Qt-${version} on Windows
and /usr/local/Qt-${version} elsewhere.
This is what's expected by users coming from Qt5, and setting the
installation prefix to "/usr/local" manually is easier than setting the
versioned variant "/usr/local/Qt-6.2.0".
[ChangeLog][Build System] The installation prefix now defaults to
/usr/local/Qt-${version} and C:/Qt/Qt-${version} like it did in Qt 5.

Ensure that Qt user projects build with sanitizer flags if Qt was
configured with any of the sanitizers enabled.
To compile Qt with sanitizer support enable any of Qt sanitizer
features.
Passing -DECM_ENABLE_SANITIZERS=address to CMake is NOT supported
anymore.
When configuring Qt using CMake directly, pass
-DFEATURE_sanitizer_address=ON
-DFEATURE_sanitizer_undefined=ON
instead of
-DECM_ENABLE_SANITIZERS=address;undefined
When configuring Qt with the configure script pass
-sanitize address -sanitize undefined
as usual.
QtConfig.cmake now records the sanitizer options that should be
enabled for all consuming projects based on the enabled Qt features.
This applies to internal Qt builds as well as well as tests an
examples.
The recorded sanitizer options are assigned to the ECM_ENABLE_SANITIZERS
variable in the directory scope where find_package(Qt6) is called.
The ECMEnableSanitizers module is included to add the necessary flags to
all targets in that directory scope or its children.
This behavior can be opted out by setting the
QT_NO_ADD_SANITIZER_OPTIONS variable in projects that use Qt and might
be handling sanitizer options differently.

Add new configure option -make minimal-static-tests and CMake option
QT_BUILD_MINIMAL_STATIC_TESTS. In conjunction with QT_BUILD_TESTS
it will enable building a minimal subset of tests when targeting
a static desktop Qt build.
In qtbase the minimal subset includes all the auto tests of testlib,
tools, corelib and cmake. In particular this will also do cmake build
tests and qmake build tests (tst_qmake)
Adjust CI instructions to enable building a minimal subset of static
tests when a platform configuration is tagged with the
MinimalStaticTests feature.

In QtSetup.cmake the PROJECT_VERSION_MAJOR variable was used to
identify prefix of 'Qt<version>HostInfoConfig.cmake'.
Qt<version>HostInfo is not found, if project version differs
from qtbase version.
Move the 'INSTALL_CMAKE_NAMESPACE' and 'QT_CMAKE_EXPORT_NAMESPACE'
variables to 'QtBuildInternalsConfig.cmake'. In this case
variables will be exposed for a wider list of internal routines.
Use the 'INSTALL_CMAKE_NAMESPACE' variable as prefix to find

Unset all QT_FEATURE_foo values for every build.
If any of FEATURE_foo is different of QT_FEATURE_foo, mark whole Qt
build as dirty. Reset FEATURE_foo for dirty builds to the calculated
value if it doesn't meet its condition.
Set Qt module as NOT FOUND if its target was not created during
configuration.
Main issue with this approach are generated files, that became trash
once the related features are disabled. This especially affects features
that enable/disable Qt modules. FooConfig.cmake files are created and
generate lots of warnings if feature was disabled. We may introduce a
module cleanup procedure at some point.
