Previously if qtbase was built with feature A set to ON, then building
qtsvg, then rebuilding qtbase with feature A set to OFF, trying to
build qtsvg would fail with an error message at configure time saying
that the feature value has changed.
This check was added quite early in the Qt CMake port, presumably to
catch accidental reconfigures that might cause long rebuilds.
This has dubious benefit though. We constantly had people telling us
they get the error without knowing what to do. The usual advice was to
remove CMakeCache.txt and reconfigure.
Instead of forcing people to suffer this dance, relax the constraint
by issuing a warning instead of an error, and make it more clear why
a rebuild might happen (a changed feature value might change
the generated module C++ header file which in turn might be included
by various project sources).

Certain platform-related variables, in this case UNIX, must be set in a
platform module, because they get cleared after the toolchain file is
loaded. Such platform modules live in upstream CMake, but there is none
yet for INTEGRITY. This manifests in an undefined UNIX variable and
"System is unknown to CMake" warnings for the project and every
configure test.
Add the CMake module "Platform/Integrity" in the cmake/platforms
directory. Add this directory to CMAKE_MODULE_PATH to let CMake load
Platform/Integrity when the toolchain file set CMAKE_SYSTEM_NAME to
"Integrity".
CMake's module directory takes precedence, when loading platform
modules. This is special for platform modules and different from the
documented behavior of CMAKE_MODULE_PATH and include().
In case the user wants to provide their own platform modules via
CMAKE_MODULE_PATH, they can instruct Qt to not add its path by setting
QT_AVOID_CUSTOM_PLATFORM_MODULES to ON.

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.

Consider a negated feature config value like the following:

If this feature was disabled, it would turn up in both,
enabled_features and disabled_features of module .pri files.
Also, QT_CONFIG would contain foo.
Expected however is that QT_CONFIG contains no-foo, and only
disabled_features contains foo.
Fix this by prepending a "no_" prefix to the value, similar to the
"no-" prefix in the qmake build. The qt_correct_config function was
adjusted to recognize "no_foo" and translate it to the qmakeish
"no-foo" config value.
Config values that start with "no_" but do not correspond to a feature
