b99321b78b CMake: Port the 'force_debug_info' feature
This feature is read-only and is ON if CMAKE_BUILD_TYPE is RelWithDebInfo
or if that value is in CMAKE_CONFIGURATION_TYPES.
It mainly exists for the qmake support.

26059d1b9b CMake: Allow building bundled 3rd party libraries in qtbase
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.

55a15a1c1b Add initial support for cross-building to iOS
Tested locally with the following configurations:
- iOS device builds (arm64)
- iOS simulator builds (x86_64)
- iOS simulator_and_device builds (fat arm64 and x86_64 archives)

All iOS builds currently require a custom vcpkg fork which contains
fixes for building the required 3rd party libraries.

qtsvg, qtdeclarative, qtgraphicaleffects and qtquickcontrols2
have also been tested to build successfully.

simulator_and_device builds are also supported, but require an umerged
patch in upstream CMake as well as further patches to vcpkg.

2fa23e46c0 Fix C++ standard detection
We cannot use a generator expression in an if statement, it does not
work. Instead, we could inspect the CMAKE_C/CXX_COMPILE_FEATURES list,
but unfortunately that's not reliable. For example it detects that ICPC
supports C++17 when in fact that depends on the installed libstdc++.
Therefore this patch revives our own configure tests.

fecefdd369 Fix mapping of features to private features
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.

400f94109d CMake: Wrap DBus1 find_package call to fix xproto not being picked up
DBus1 (1.12) configuration file breaks PKG_CONFIG environment
variables and will thus prevent other libraries to be picked up
by pkgconfig. Main sympthom is that xproto is not getting picked
up anymore, which results in hundreds of lines of warnings about
this being printed.

Work around that by wrapping the call to find_package(DBus1) and
restoring the environment.

9b0b464e82 Write find_dependency() calls in Qt Module config files
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.

ba7c62eed5 Fix sub-architecture (instruction sets / SIMD) handling
In qmake there are at least 2 things to know regarding
sub-architectures and instruction sets.

Which instruction sets does the compiler know to compile for,
represented by the various config.tests and features in
qtbase/configure.json.

And which instructions sets are enabled by the compiler by default,
represented by the configure.json "architecture" test and accessed
via QT_CPU_FEATURES.$$arch qmake argument.

Before this patch there was some mishandling of the above concepts
in CMake code.

The former can now be checked in CMake with via TEST_subarch_foo and
QT_FEATURE_foo (where foo is sse2, etc).

The latter can now be checked by
TEST_arch_${TEST_architecture_arch}_subarch_foo
(where foo is sse2, etc and the main arch is dynamyicall evaluated).

The configurejson2cmake script was adjusted to take care of the above
changes, and the cmake files were regenerated as well.
