Our only way to detect whether the user requests an Android build of Qt
was to peek into the CMake toolchain file if it is specified. If the
toolchain file contains a certain magic string, we decide that we're
building for Android.
This approach is fragile and bound to break should the Android toolchain
file's magic string ever change.
Now, we assume an Android build if any of our ANDROID_* cache variables
is set. In that case, we do not peek into the toolchain file.

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.

QtAutoDetect.cmake did read the (possibly detected) toolchain file and
looked for the string "The Android Open Source Project" to deduce that
we want to build for Android. This has been done, because we're
autodetecting the platform before the first project comment, i.e. before
the toolchain file is loaded.
This magic string detection is a bit fragile, and we need a similar
approach for WebAssembly. A more robust approach would be to fetch the
value of CMAKE_SYSTEM_NAME from the toolchain file without actually
loading it.
Now, we run a CMake script that includes the toolchain file and prints
variables were interested in. The calling code reads these variables and
stores them in prefixed variables in the current scope.

Three different people have encountered the issue that calling
calling qt-cmake on a project prints 1000 inclusion lines of the same
qt toolchain file, and then CMake bails out saying can't find the
CMAKE_MAKE_PROGRAM Ninja.
This happened because people accidentally called qt-cmake to configure
qtbase (instead of just cmake), which created a toolchain file that
chainloads itself recursively.
Error out when configuring qtbase, and when using the generated
toolchain file in the case when it would try to include itself.
The solution is to remove the qtbase CMakeCache.txt file, and
configure qtbase again, so it generates a proper qt.toolchain.cmake
file.
If somebody feels enthusiastic, they can move the check into the
qt-cmake and qt-cmake-private shell scripts, and error out before the
qtbase/CMakeCache.txt is polluted with the wrong toolchain file.
That is left for people that feel more comfortable with bash and batch
scripting.

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).

To build all targets of a certain configuration use "ninja all:Release"

is used by AUTOMOC.
When configured with -DCMAKE_CONFIGURATION_TYPES="Debug;Release"
the debug version of moc is used by AUTOMOC.
Framework builds and Ninja Multi-Config don't currently work together

which packages to find in every tests.pro project.
Instead of having a separate standalone project, modify the top level
project and associated CMake code to allow passing a special
QT_BUILD_STANDALONE_TESTS variable, which causes the top level project

location.
This also means that when building a repo, we generate a
${repo_name}TestsConfig.cmake file which does find_package on all the
