Standalone test projects have the following condition in the
beginning of their project:
if(NOT QT_BUILD_STANDALONE_TESTS AND NOT QT_BUILDING_QT)
find_package(Qt6BuildInternals COMPONENT STANDALONE_TEST)
endif()
When configuring the project the first time, QT_BUILDING_QT is not
set, find_package is called, configuration succeeds.
But because standalone projects implicitly include QtSetup.cmake,
that file sets the QT_BUILDING_QT cache var to true, and upon test
reconfiguration, cmake errors out with:
Unknown CMake command "qt_internal_add_test"
or similar.
This happens because QT_BUILDING_QT is true on the second
reconfiguration and the find_package mentioned above is not executed
anymore, leading to unknown internal command errors.
Set a new QT_INTERNAL_IS_STANDALONE_TEST variable when we detect
a standalone test and check for its value in QtSetup so we don't
set QT_BUILDING_QT to TRUE anymore.
Adjust a few code locations where QT_BUILDING_QT being false might
trigger different behavior for standalone tests.

The check_language macro spawns a new cmake subprocess to detect
availability of a language. We use that to detect availability of
the Objective-C/C++ languages when targeting Apple platforms.
That's problematic because the parent process CFLAGS / LDFLAGS env
vars influences the result of the subprocess compiler detection,
and in some cases that can fail the detection.
An example of that is passing iOS specific flags which then get
mixed with the default macOS flags added by CMake, resulting in
a linker failure.
Instead of using check_language, explicitly enable the Objective-C
and C++ languages when targeting Apple platforms because we know
that we need them for compiling Qt.
This avoids the issue because enable_language is not spawning a
separate cmake sub-process and thus passes more information to the
underlying try_compile project to ensure a successful check.
The change also means that CMake will error out earlier in case if the
Objective-C compiler is not found, which was not the case before.

When configuring Qt the second time it might be situation that
the set of qt_find_package calls is changed. One of the scenarios
is the changing of the submodule list that needs to be built in
top-level builds. It's also applicable for Qt features that lead to
extra package lookup in the unlocked subdirectories. Current approach
collects packages that were found at the previous run and skips
search of the packages that are missing. The problem is that
it also skips packages even if qt_find_package was not called at
previous run. QT_INTERNAL_PREVIOUSLY_SEARCHED_PACKAGES collects
all packages that were actually searched at the previous run
to make sure that qt_find_package don't skip packages that
appeared at second run only.

Until cmake is fixed, we can work around the issue by not adding
designer as a dependency when building EP examples, because no example
tries to use the app.
We can't exclude all apps from example dependencies because some
modules use qt_internal_add_app for tools as well, which are called
from public CMake API and also examples.
An example of this is qtapplicationmanager.
Given that we can't exclude all apps, introduce a function to
allow skipping single targets when building EP examples.
This will allow excluding designer specifically.
The examples will now depend on a new ${repo}_src_for_examples target
rather than ${repo}_src, which will exclude skipped targets.

Instead of constantly trying to find packages by calling

found during initial configuration. Then on a second reconfiguration,
skip looking for packages that were not found on the initial
configuration.
This speeds up reconfiguration on certain platforms and repos.

Note this is a behavior change from how find_package is used in most
CMake projects, where if a package was previously missing, the
developer can just install the package and reconfigure to pick it up.
With this change, they will first have to remove their CMakeCache.txt
file and configure from scratch, or remove the
QT_INTERNAL_PREVIOUSLY_FOUND_PACKAGES cache variable and reconfigure.
For this reason, we enable this behavior by default only in
-developer-builds.
Builders can also opt in or out by setting the
QT_INTERNAL_SAVE_PREVIOUSLY_FOUND_PACKAGES variable to either ON or
OFF.
Note this behavior does not apply to user projects, or direct
find_package calls (as opposed to qt_find_package).

syncqt.pl adds an extra dependency on perl when building Qt. Modern C++
provides the convenient cross-platform way to access a filesystem and
to use regular expressions, so we may replace the perl script with C++
application. The syncqt executable is built at configure time and
installed as QtCore tool. It's running at configure time to deliver the
required header files for IDE to build a consistent code model and at
the build time to keep tracking changes in header files and generate
the missing aliases without reconfiguring. 'syncqt' only parses header
files from a CMake build tree, so the resulting Qt installation only
contains interfacing headers that belong to the platform that Qt is
built for. 'sync.profile' files are not used as the 'source of truth'
for sync qt procedure anymore, all the necessary information is taken
from either CMake files at configure time or from the module header
files while parsing them.
syncqt.pl is still in place since it's required as fallback solution
for a smooth transition to the new syncqt implementation for all qt
repositories.
This patchset only enables the C++ based syncqt for 'qtbase'
repository.
From the performance perspective C++ version works faster then perl
script, also the configure time is reduced significally on subsequent
reconfigurations - up x2 times faster when re-configuring repository,
but it also takes time to compile the tool itself the first time.
Numbers for qtbase:
syncqt.pl syncqt.cpp
initial: 0m16,035s 0m20,413s
reconfig: 0m6,819s 0m3,725s
The syncing procedure can be run separately for each module using
<ModuleName>_sync_headers targets. The 'sync_headers' target can be
used to sync all the modules at once.

When building qtsvg examples as external projects on Windows

fail with an error message like:
ninja: error:
'C:/Users/qt/work/qt/qtsvg/lib/Qt6SvgWidgets.lib', needed by

This can be reproduced locally on Windows if one calls
'ninja svgviewer' instead of just 'ninja'. I wasn't able to reproduce
it on macOS, although I have seen some peculiarities in the
dependencies there as well.
External project examples depend on the ${repo_name}_src custom
target to ensure all Qt modules are built, so one would expect that
dependency to be sufficient.
While trying to figure out what's going wrong, I noticed that running
'ninja -t query qtsvg_src:Debug' showed dependencies on Release
libraries, which should not happen. The :Release target looked fine
though.
I'm still not quite sure why the Release libraries are not built
on the first ninja run, despite the example having a proper dependency
on qtsvg:Release.
Running 'ninja svgviewer' a few more times ends up succeeding at one
point, because the SvgWidgets Release library does get built in
parallel with the failing example, and the next rebuild would
succeed.
While trying to fix the :Debug target to have proper dependencies, I
noticed that we add dependencies to the ${repo_name}_src custom target
via the DEPENDS option of add_custom_target(). That is incorrect,
that option should only be used for file level dependencies.
For target dependencies, add_dependencies should be used.
Doing that fixed both the :Debug dependencies as well as the Windows
issue, which is good enough for me.

When recording which package version to look for in
QtFooModuleDependencies.cmake and other files like it,
instead of using PROJECT_VERSION, use the version of the
package that contains the dependency.
For example if we're hypothetically building the qtdeclarative repo
from the 6.4 branch, against an installed 6.2 qtbase, then
the Qt6QmlModuleDependencies.cmake file will have a
find_package(Qt6Core 6.2) call because qtdeclarative's
find_package(Qt6Core) call found a 6.2 Core when it was configured.
This allows switching the versioning scheme of specific Qt modules
that might not want to follow the general Qt versioning scheme.
The first candidate would be QtWebEngine which might want to
follow the Chromium versioning scheme, something like
Qt 6.94.0 where 94 is the Chromium major version.
Implementation notes.
We now record the package version of a target in a property
called _qt_package_version. We do it for qt modules, plugins,
3rd party libraries, tools and the Platform target.
When we try to look up which version to write into the
QtFooModuleDependencies.cmake file (or the equivalent Plugins and
Tools file), we try to find the version
from a few sources: the property mentioned above, then the
Qt6{target}_VERSION variable, and finally PROJECT_VERSION.
In the latter case, we issue a warning because technically that should
never have to happen, and it's a bug or an unforeseen case if it does.
A few more places also need adjustments:
- package versions to look for when configuring standalone
tests and generating standalone tests Config files
- handling of tools packages
- The main Qt6 package lookup in each Dependencies.cmake files
Note that there are some requirements and consequences in case a
module wants to use a different versioning scheme like 6.94.0.
Requirements.
- The root CMakeLists.txt file needs to call find_package with a
version different from the usual PROJECT_VERSION. Ideally it
should look for a few different Qt versions which are known to be
compatible, for example the last stable and LTS versions, or just
the lowest supported Qt version, e.g. 6.2.6 or whenever this change
would land in the 6.2 branch.
- If the repository has multiple modules, some of which need to
follow the Qt versioning scheme and some not,
project(VERSION x.y.z) calls need to be carefully placed in
subdirectory scopes with appropriate version numbers, so that
qt_internal_add_module / _tool / _plugin pick up the correct
version.
Consequences.
- The .so / .dylib names will contain the new version, e.g. .so.6.94
- Linux ELF symbols will contain the new versions
- syncqt private headers will now exist under a
include/QtFoo/6.94.0/QtFoo/private folder
- pri and prl files will also contain the new version numbers
- pkg-config .pc files contain the new version numbers
- It won't be possible to write
find_package(Qt6 6.94 COMPONENTS WebEngineWidgets) in user code.
One would have to write find_package(Qt6WebEngineWidgets 6.94)
otherwise CMake will try to look for Qt6Config 6.94 which won't
exist.
- Similarly, a
find_package(Qt6 6.4 COMPONENTS Widgets WebEngineWidgets) call
would always find any kind of WebEngine package that is higher than
6.4, which might be 6.94, 6.95, etc.
- In the future, if we fix Qt6Config to pass EXACT to its
subcomponent find_package calls,
a find_package(Qt6 6.5.0 EXACT COMPONENTS Widgets WebEngineWidgets)
would fail to find WebEngineWidgets, because its 6.94.0 version
will not be equal to 6.5.0. Currently we don't pass through EXACT,
so it's not an issue.

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).

By default when building ExternalProjects, even if the main ninja
invocation has -v passed, that won't be passed to the nested ninja
calls.
When building examples in the CI, we want to see the full command line
invocations.
Allow passing -v to the nested EP ninja calls by configuring Qt with
-DQT_INTERNAL_VERBOSE_EXAMPLES=ON, which we will use in our CI.
We don't want to add -v by default because if the main ninja does not
have one, the nested calls will still be verbose.

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.

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.

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.

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).

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.

Instead of nesting the external project build dir under the current
binary dir, place the EP build dir where it would usually be when we
use add_subdirectory.
Shorten the name of the external project to just ${subdir} instead
of using the relative current binary dir path.
Place the EP prefix and stamp dirs under a new ${subdir}-ep folder
next to the example build dir.
Overall this places example executables where you'd usually expect
them to be, as well as shortens a bunch of build paths to circumvent
path limit issues when building on Windows.
