f4417bf7e8 Check whether CMake was built with zstd support
CMake 3.18 introduced the file(ARCHIVE_CREATE) API that we use with
COMPRESSION Zstd for compressing corelib's mimedatabase.

It's possible to build CMake without proper zstd support, and we have
encountered such builds in the wild where the file(ARCHIVE_CREATE) call
crashes.

Add a configure test to determine whether CMake properly supports the
Zstd compression method.

659817e287 CMake: Fix building multi-arch universal macOS Qt
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.

2354274f39 CMake: Allow embedding debug info in object files with MSVC
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.

Some of the Find modules are rewritten to take the  specified version

This involves moving around the code for creating a target, after

759da6742a CMake: Generate information about 3rdparty libs in module .pri files
For modules that are not yet ported to CMake and that use
   QMAKE_USE += libfoo
we need to provide the information about libfoo in the qt_lib_XXX.pri
files.

Also, we now generate qt_ext_XXX.pri files for bundled 3rdparty libs.

4545eadd3e CMake: Port the 'static_runtime' feature
This feature is Windows-only and must be turned on manually.
For MSVC it sets the MSVC_RUNTIME_LIBRARY target property.
For MinGW it adds the -static linker flag.

67ee92f4d8 CMake: Handle automatic rpath embedding correctly
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).
