When CMake generates compilation rules, it extracts the values from
INTERFACE_INCLUDE_DIRECTORIES and checks if any of the values
are framework paths.
If they are, instead of adding an -I ./lib/My.framework to the
compilation rules, it adds -iframework ./lib or -F ./lib.
The same transformation does not happen when AUTOMOC passes include
paths to moc, nor during a headersclean check. The values there
are passed verbatim, with an -I prepended.
This causes issues when the include file name is the same as the
framework name.
E.g. #include <QtQml> + -I ./lib/QtQml.framework because moc
then ends up silently including the shared library
./lib/QtQml.framework/QtQml
instead of the header
./lib/QtQml.framework/Headers/QtQml
This can lead to a variety of silent issues during moc generation,
because all the definitions of QtQml will be missing.
Unfortunately, there does not seem to be a clean way to fix this in
the build system due to CMake semantics.
See https://gitlab.kitware.com/cmake/cmake/-/issues/23337 for details.
We can mitigate the issue by ensuring that
-I ./lib/QtQml.framework/Headers
comes before
-I ./lib/QtQml.framework
by manipulating the order of values in INTERFACE_INCLUDE_DIRECTORIES.
We might want to consider implementing an additional mitigation in
AUTOMOC, so that it filters out include paths like
-I ./lib/QtQml.framework, thus ensuring that a newer CMake version
will not exhibit the same issue when used with an older Qt.
We could consider doing the same in moc. The advantage of doing it
in moc is that that moc will consider fewer invalid include paths
when searching for headers.

The -mno-direct-extern-access tells the compiler and linker that
references to symbols outside this ELF module mustn't be direct and must
instead always go through the GOT or PLT (the PLT can additionally be
disabled with -fno-plt). The ELF protected visibility tells the compiler
and linker that this symbol is present in the dynamic symbol table as an
export, but it cannot be interposed by another ELF module.
This option is required for user code to link properly to Qt, otherwise
they will get linker errors (assuming GNU binutils >= 2.39) or runtime
failures (glibc >= 2.35). Both versions of glibc and binutils are older
than GCC 12, so it's a safe assumption they are in use and downgrading
the toolchain or libc is not supported. Adding this option to the
compilation is assured for CMake and qmake-based projects.
For example, all accessess to QCoreApplication::self in QtCore, after
this change and with GCC 12 are relocation-free and direct:
000000000013ebf0 <QCoreApplicationPrivate::checkInstance(char const*)>:
13ebf0: cmpq $0x0,0x4f73d0(%rip) # 635fc8 <QCoreApplication::self>
13ebf8: setne %al
13ebfb: je a90fe <QCoreApplicationPrivate::checkInstance(char const*) [clone .cold]>
13ec01: ret
Meanwhile, accesses to the same variable in other modules are indirect
via the GOT:
66650: mov 0x876e1(%rip),%rax # edd38 <QCoreApplication::self@Qt_6>
66657: cmpq $0x0,(%rax)
This replaces the -Bsymbolic and -Bsymbolic-functions (broken)
functionality that Qt has been using or attempting to use since ~2006.

After the update to the CMake based build system the ability to
generate pkgconfig files, like it was with QMake, was lost.
This patch adds pkgconfig generation again via a new internal command
named qt_internal_export_pkg_config_file.
The functionality of this command consists in checking if the target
is internal. Then gets the compile definitions. It performs a search
for dependencies that is somewhat similar to
qt_get_direct_module_dependencies, although it won't recurse down for
more deps. Each dependency is then again, checked if it's internal or
has a public interface. Later these deps get deduplicated and lastly
a pkgconfig file is filled.
The resulting pkgconfig files of many of the Qt6 packages were
validated via invocations of `pkg-config --validate` and
`pkg-config --simulate` commands and later used to build local
projects plus tests that use the pkg-config provided details at
compilation time.
Although it has some limitations, with qt_internal_add_qml_module if
it specifies non-public deps these won't be listed and with non-Qt
requirements, notably in static builds, not being appended to the
PkgConfig file.

When configuring a static Qt with the -qt-zlib option and the build
system creates a 3rd party header module QtZlib, syncqt
does not generate a QtZlib header file that would include all its
public headers.
Then when the QtSvgDepends header is generated, it would add an
#include <QtZlib> which would break compilation of the QtSvg PCH
file (which compiles QtSvgDepends).
We have logic to exclude addition of headers from regular 3rd party
static libraries, but not header only 3rd party libraries.

make sure it works across repos by exporting the relevant properties.

target_sources(qt_module INTERFACE $<TARGET_OBJECTS:plugin_init>)
so that they are linked into the final executable or shared library
via qt module usage requirement propagation.
This reduces the build times of user projects.
The link line placement of the object files should be correct for all
linux-y linkers because the only dependency for the object files is
Core and the Gui -> plugin -> Gui -> Core cycle does not hamper that
from empirical observations.
As a consequence of the recent change not to link plugin initialization
object files into static libraries, as well not having to compile the
files in user projects, we can get rid of the
_qt_internal_disable_static_default_plugins calls in various places.
A side note.
Consider a user static library (L) that links to a Qt static library
(Gui) which provides plugins (platform plugins).
If there is an executable (E) that links to (L), with no direct
dependency to any other Qt module and the intention is that the
executable will automatically get the platform plugin linked,
then (L) needs to link PUBLIC-ly to (Gui) so that the plugin usage
requirements are propagated successfully.
This is a limitation of using
target_sources(qt_module INTERFACE $<TARGET_OBJECTS:plugin_init>)
which will propagate object files across static libraries only if
qt_module is linked publicly.
One could try to use
target_link_libraries(qt_module
INTERFACE $<TARGET_OBJECTS:plugin_init>)
which preserves the linker arguments across static libs even if
qt_module is linked privately, but unfortunately CMake will lose
dependency information on Core, which means the object files might be
placed in the wrong place on the link line.
As far as I know this is a limitation of CMake that can't be worked
around at the moment.
Note this behavior was present before this change as well.

In commit 013abe3206, I add

to suppress MSVC warnings like:
warning C4996: 'strncpy': This function or variable may be unsafe.
However, when compiling some internal tools, such as qmake and qdoc,
such warnings also exist. To suppress this kind of warning entirely,
_CRT_SECURE_NO_WARNINGS definition should be added for all Qt internal
targets when using MSVC compiler.

Remove code duplication by calling qt6_add_plugin() from

Separate out the public and internal arguments for the

Provide them via commands instead for greater robustness.
This separation allows other Qt repos to access the appropriate
set of keywords where they define commands that forward
on to *_add_plugin() in their implementations. Retain
the old variables for now to simplify the integration
steps for updating other repos. The old variables can

In static builds, we cannot allow any part of the main build to make a
call to find_package(Qt6...) where such a call may load a
Qt6*Plugins.cmake file. That would add additional dependencies to the
main module targets, setting up a circular dependency in the set of
*Config.cmake files which cannot be resolved. This scenario would be
triggered by per-repo builds or user projects.
But Qt's tools and other executables still need to load some plugins
in static builds. Sometimes a platform plugin may be enough, other
times we may want all supportable plugins (e.g. Qt Designer).
Therefore, add all plugins we can identify as relevant for an
executable that is part of the Qt build, but add them directly to the
executable without affecting the linking relationships between the
main module libraries.
Also remove the now unnecessary check for QT_BUILD_PROJECT_NAME in
top level builds because there should be no difference between per-repo
and top level builds any more (as far as linking static plugins is
concerned).
Examples that build as part of the main build will still build
successfully after this change, but they will not run if they require
a platform plugin. Examples need to be moved out to a separate build
where they can call find_package(Qt6) without QT_NO_CREATE_TARGETS
set to TRUE to be runnable (see QTBUG-90820).

To be able to link a Release user project against a RelWithDebInfo Qt we
set several IMPORTED_*_RELEASE properties in
the *AdditionalTargetInfo.cmake file of each Qt module.
The EntryPoint module however is a bit special as it is an
INTERFACE_LIBRARY linking publicly against a static
library (EntryPointimplementation). Its *AdditionalTargetInfo.cmake file
was almost empty, because qt_internal_export_additional_targets_file was
called before EntryPointImplementation was set up. Also,
qt_internal_add_module, which calls
qt_internal_export_additional_targets_file, does not know that we want
to export the EntryPointImplementation target.
We fix this by telling qt_internal_add_module(EntryPoint) to not
generate the *AdditionalTargetInfo.cmake file and call
qt_internal_export_additional_targets_file later to take the targets
EntryPoint and EntryPointImplementation into consideration.
qt_internal_add_module learned the option NO_ADDITIONAL_TARGET_INFO to
turn off the generation of *AdditionalTargetInfo.cmake files.

When a CMake release introduces a new policy that affects most Qt
modules, it may be appropriate to make each module aware of that newer
CMake version and use the NEW policy without raising the minimum CMake
version requirement. To reduce the churn associated with making that
change across all Qt modules individually, this change allows it to be
updated in a central place (qtbase), but in a way that allows a Qt
module to override it in its own .cmake.conf file if required (e.g. to
address the issues identified by policy warnings at a later time). The
policies are modified at the start of the call to
qt_build_repo_begin().
For commands defined by the qtbase module, qtbase needs to be in
control of the policy settings at the point where those commands are
defined. The above mechanism should not affect the policy settings for
these commands, so the various *Config.cmake.in files must not specify
policy ranges in a way that a Qt module's .cmake.conf file could
influence.
Starting with CMake 3.12, policies can be specified as a version range
with the cmake_minimum_required() and cmake_policy() commands. All
policies introduced in CMake versions up to the upper limit of that
range will be set to NEW. The actual version of CMake being used only
has to be at least the lower limit of the specified version range.
This change uses cmake_minimum_required() rather than cmake_policy()
due to the latter not halting further processing upon failure.
