The mold linker is a new linker for Linux that provides faster link
times compared to BFD ld, ld.gold and lld.
It can be found at https://github.com/rui314/mold
To build Qt with mold, ensure that the binary in your PATH and then
configure Qt with with either
cmake /path/to/qtbase -DINPUT_linker=mold
or
/path/to/qtbase/configure --linker mold
The change was tested with gcc 9, clang 10, clang 12, mold
1.0.0. Only qtbase and qtdeclarative (and dependencies) were tested.

Xcode allows building a project targeting either the device or
simulator sysroot in one single build dir, but for the sysroot
switching to work there should be no linker or compiler flags
referencing absolute paths of a specific sysroot.
During CMake configuration of a project targeting iOS, all found
system libraries will be within one single sysroot, either the device
one or the simulator one, whichever one was passed to
CMAKE_OSX_SYSROOT. CMake will then generate the Xcode project
and pass those absolute paths, which makes sysroot switching within
Xcode not work.
To avoid that, the CMake documentation recommends passing linker and
framework flags of the form '-lfoo' and '-framework bar' instead of
absolute paths. Xcode then takes care of setting the correct framework
search path.
Zlib is one of the libraries found in the iOS sysroot and thus passed
as absolute path.
To avoid that, create a new FindWrapZLIB find script. The target it
creates will pass the absolute path to the library on non Apple
platforms and an -lz linker flag on Apple platforms (macOS and iOS).
To avoid issues with target global promotion when system PNG package
is found, ensure that a found ZLIB::ZLIB target is promoted to global
manually in src/gui/configure.cmake.

Use the same approach we use for iOS, which is to set multiple
CMAKE_OSX_ARCHITECTURES values and let the clang front end
deal with lipo-ing the final libraries.
For now, Qt can be configured to build universal macOS libraries by
passing 2 architectures to CMake, either via:
-DCMAKE_OSX_ARCHITECTURES="x86_64;arm64"
or
-DCMAKE_OSX_ARCHITECTURES="arm64;x86_64"
Currently we recommend specifying the intel x86_64 arch as the first
one, to get an intel slice configuration that is comparable to a
non-universal intel build.
Specifying the arm64 slice first could pessimize optimizations and
reduce the feature set for the intel slice due to the limitation
that we run configure tests only once.
The first specified architecture is the one used to do all the
configure tests.
It 'mostly' defines the common feature set of both architecture
slices, with the excepion of some special handling for sse2 and
neon instructions.
In the future we might want to run at least the Qt architecture config
test for all specified architectures, so that we can extract all the
supported sub-arches and instruction sets in a reliable way.
For now, we use the same sse2 hack as for iOS simulator_and_device
builds, otherwise QtGui fails to link due to missing
qt_memfill32_sse2 and other symbols.
The hack is somewhat augmented to ensure that reconfiguration
still succeeds (same issue happened with iOS). Previously the sse2
feature condition was broken due to force setting the feature
to be ON. Now the condition also checks for a special
QT_FORCE_FEATURE_sse2 variable which we set internally.
Note that we shouldn't build for arm64e, because the binaries
get killed when running on AS with the following message:
kernel: exec_mach_imgact: not running binary built against
preview arm64e ABI.
Aslo, by default, we disable the arm64 slice for qt sql plugins,
mostly because the CI provisioned sql libraries that we depend on only
contain x86_64 slices, and trying to build the sql plugins for both
slices will fail with linker errors.
This behavior can be disabled for all targets marked by
qt_internal_force_macos_intel_arch, by setting the
QT_FORCE_MACOS_ALL_ARCHES CMake option to ON.
To disble it per-target one can set
QT_FORCE_MACOS_ALL_ARCHES_${target} to ON.

Introduce a new feature called 'FEATURE_msvc_obj_debug_info' which
should allow usage of sccache for Windows MSVC configs.
Enabling the feature will replace the default '/Zi' compile flag
that CMake sets in Windows-MSVC.cmake with '/Z7'.
This ensures that the debug info is placed into the compiled object
file instead of placing it in the compilation .pdb file via
mspdbsrv.exe.
The final pdb file will still be created for shared libraries and
executables due to the linker '/debug' flag.
Static libraries will not have a .pdb file, instead the debug info
being embeeded in the .lib file.
The downsides of using '/Z7' are more disk space usage, slower
link times, more memory used for linking because the linker needs
to deal with more symbols.
The upside is that caching each indepedent cl.exe call is possible.
This is what Chromium uses with goma, and Firefox with sccache.
We're not enabling the feature by default to allow easier
testing (and switching it off) in the CI if it proves not to be
feasible.
It will probably have to be disabled at least for building
qtwebengine due to high memory requirements.

Instead of using CMAKE_INSTALL_RPATH to embed an absolute path
to prefix/libdir into all targets, use the more sophisticated aproach
that qmake does.
For certain targets (modules, plugins, tools) use relative rpaths.
Otherwise embed absolute paths (examples, regular binaries).
Installed tests currently have no rpaths.
On certain platforms rpaths are not used (Windows, Android,
iOS / uikit).
Frameworks, app bundles and shallow bundles should also be handled
correctly.
Additional rpaths can be provided via QT_EXTRA_RPATHS variable
(similar to the -R option that configure takes).
Automatic embedding can be disabled either via QT_FEATURE_rpath=OFF
or QT_DISABLE_RPATH=ON.
Note that installed examples are not relocatable at the moment (due
to always having an absolute path rpath), so this is a missing feature
compared to qmake. This is due to missing information on where
examples will be installed, so a relative rpath can not be computed.
By default a Qt installation is relocatable, so there is no need to
pass -DQT_EXTRA_RPATHS=. like Coin used to do with qmake e.g. -R .
Relative rpaths will have the appropriate 'relative base' prefixed
to them (e.g $ORIGIN on linux and @loader_path on darwin platforms).
There is currently no support for other platforms that might have a
different 'relative base' than the ones mentioned above.
Any extra rpaths are saved to BuildInternalsExtra which are re-used
when building other repositories.
configurejson2cmake modified to include correct conditions for the
rpath feature.
It's very likely that we will need a new qt_add_internal_app()
function for gui apps that are to be installed to prefix/bin.
For example for Assistant from qttools. Currently such apps
use qt_add_executable().
The distinction is necessary to make sure that relative rpaths are
embedded into apps, but not executables (which tests are part of).

A few things are needed to accomplish that:
- the python scripts do not ignore certain system_foo features anymore
(it is a hardcoded list for now just to be safe)
- configurejson2cmake now outputs
qt_find_package(WrapSystemFoo) calls for bundled libraries
(see below)
- the harfbuzz .pro file is modified to accommodate pro2cmake
not being able to correctly parse some conditional scopes
- the freetype .pro file is modified to make sure linking of the
library succeeds without duplicate symbol errors, which qmake
doesn't encounter due to magical exclusion of cpp files that are
included in other cpp files (presumably for include moc_foo.cpp
support)
- feature evaluation for Core, Gui, Network now happens in the
qtbase/src directory, so that bundled libraries can be conditionally
built
- for each bundled library there are now two FindWrap scripts:
- FindWrapSystemFoo which finds an installed library in the system
- FindWrapFoo which either uses the system installed library or
the built bundled one depending on a condition
- projects that intend to use bundled libraries need to link against
WrapFoo::WrapFoo instead of WrapSystemFoo::WrapSystemFoo targets
(this is handled by pro2cmake).
Unfortunately manually added qt_find_package(WrapFoo) calls might
still be needed as is the case for WrapFreetype and others.
- a new cmake/QtFindWrapHelper.cmake file is added that provides
a macro to simplify creation of WrapFoo targets that link against
a bundled or system library. The implementation is fairly ugly
due to CMake macro constraints, but it was deemed better than
copy-pasting a bunch of almost identical code across all
FindWrapFoo.cmake files.
- a qtzlib header-only module is now created when using bundled
zlib, to provide public syncqt created headers for consumers
that need them. These are projects that have
'QT_PRIVATE += zlib-private' in their .pro files
(e.g. qtimageformats, qtlocation, qt3d, etc.)
This is unfortunately needed due to QtNetwork using zlib
types in its private C++ API.
The change includes support for building the following bundled
libraries:
- zlib
- libpng
- libjpeg
- Freetype
- Harfbuzz-ng
- PCRE2
The following 3rd party libraries are still using an old
implementation within the CMake build system, and should be migrated
to the new one in the near future:
- double-conversion
- Old harfbuzz
The are a few libraries that are not yet ported:
- system-sqlite
- systemxcb
- maybe others
Among other things, this change allows building qtbase on Windows
without requiring vcpkg.

When a feature generates a private feature, we should not just repeat
the condition but also make it depend on the original feature. In qmake
features had different outputs, while we have a 1:1 mapping. For example
the developer_build feature had "private_tests" as an output feature.
There's no condition attached to the feature and auto-detect is off, so
we'd generate
qt_feature("developer_build" AUTODETECT OFF)
qt_feature("private_tests" AUTODETECT OFF)
and that's wrong, because when the user enables the visible feature
(developer_build) we want it to propagate to the private_tests feature.

This change introduces a new function called qt_find_package()
which can take an extra option called PROVIDED_TARGETS, which
associates targets with the package that defines those targets.
This is done by setting the INTERFACE_QT_PACKAGE_NAME and
INTERFACE_QT_PACKAGE_VERSION properties on the imported targets.
This information allows us to generate appropriate find_dependency()
calls in a module's Config file for third party libraries.
For example when an application links against QtCore, it should also
link against zlib and atomic libraries. In order to do that, the
library locations first have to be found by CMake. This is achieved by
embedding find_dependency(ZLIB) and find_dependency(Atomic) in
Qt5CoreDependencies.cmake which is included by Qt5CoreConfig.cmake.
The latter is picked up when an application project contains
find_package(Qt5Core), and thus all linking dependencies are resolved.
The information 'which package provides which targets' is contained
in the python json2cmake conversion script. The generated output of
the script contains qt_find_package() calls that represent that
information.
The Qt5CoreDependencies.cmake file and which which dependencies it
contains is generated at the QtPostProcess stop.
Note that for non-static Qt builds, we only need to propagate public
3rd party libraries. For static builds, we need all third party
libraries.
In order for the INTERFACE_QT_PACKAGE_NAME property to be read in any
scope, the targets on which the property is set, have to be GLOBAL.
Also for applications and other modules to find all required third
party libraries, we have to install all our custom Find modules, and
make sure they define INTERFACE IMPORTED libraries, and not just
IMPORTED libraries.
