CMake has logic to rewrite build rpaths that contain
CMAKE_STAGING_PREFIX to instead point to CMAKE_INSTALL_PREFIX.
This breaks running executables from the build directory, because
their build rpath will point to a location where the libraries might
not exist yet (we didn't install Qt yet).
Work around this by setting CMAKE_STAGING_PREFIX to a fake path, so
that CMake does not do the rewriting anymore.
CMAKE_STAGING_PREFIX needs to be set at subdirectory scope, not
function scope, which is why
qt_internal_apply_staging_prefix_build_rpath_workaround() is a macro
that is called from within each Qt internal function that creates
a target.
The workaround can be disabled by configuring with
-DQT_NO_STAGING_PREFIX_BUILD_RPATH_WORKAROUND=ON
The downside of this workaround is that it breaks per-subdirectory
install rules like 'ninja src/gui/install'.
Regular global installation like 'ninja install' works fine.
This is similar to what we do for tests in
qt_set_up_fake_standalone_tests_install_prefix()
introduced by 20292250d4
The reason it's not as good for other target types is because in
contrast to tests, we do want to install them.
In case if someone does call `ninja src/gui/install' they will most
likely get a permission error, telling them it's not possible to
install into

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.

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.

HEADER_MODULEs use the INTERFACE visibility to link libraries. This
causes a transitional propagating of the Qt-internal compile definitions
and options to the user targets.
This commit avoids an implicit adding of the Qt::PlatformModuleInternal
library to the HEADER_MODULEs and stops propagation of the Qt-internal
compile definitions and options. If module wants the transitional
propagation of some properties, this needs to be done explicitly.

In cmake, targets are used as an entity for modules. This causes a
number of problems when we want to manipulate a module as a separate
entity with properties associated with it.
The _qt_internal_module_interface_name target property is introduced to
represent the module entity. All modules write a name to this property,
which will subsequently expand into the module name matched with
the module name in qmake.
The 'qt_internal_module_info' function is responsible for providing the
correct values for the module properties used when working with a module
target.
Unlike qmake, for internal modules in cmake it is expected that the
Private suffix will be specified explicitly. In case the user wants to
have a different module name, an additional argument
MODULE_INTERFACE_NAME of the qt_internal_add_module function is
introduced.
This also changes the way how target dependencies are collected and
resolved. Since the 'Private' suffix no longer means an unique
identifier of the module 'Private' part, we look for the both Private
and non-Private package names when resolving dependencies.
TODO: This change doesn't affect the existing internal modules, so to
keep compatibility with the existing code the existing internal modules
create 'Private' aliases. The code that provides backward compatibility
must be removed once all internal modules will get the proper names.

Instead of compiling the plugin initializers as part of a user
project, pre-compile them as object libraries while building Qt.
The installed object libraries can then be used with
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

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

Remove code duplication by calling qt6_add_plugin() from
qt_internal_add_plugin().
Separate out the public and internal arguments for the
variables defined in QtBuild.cmake for these functions.
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
be removed once there are no more references left to
them in any repo.

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.
