bd4726fa5d CMake: Pass CMAKE_OSX_ARCHITECTURES to try_compile on macOS
There was an inconsistency where configuring qtbase on Apple Silicon
with the following command line produced different results rom the
second variant.

$ cmake ../qtbase -DCMAKE_OSX_ARCHITECTURES=arm64
vs
$ CMAKE_OSX_ARCHITECTURES=arm64 cmake ../qtbase

That happened because the CMAKE_OSX_ARCHITECTURES variables was not
passed to project-based try_compile calls. This resulted in compile
tests like SIMD avx to succeeded on Apple silicon, which shouldn't.

To address that, always pass the architecture on macOS if it's
specified.

054b66a657 CMake: Provide old style CMake variables for target info
This change provides the following per-module variables
Qt6Widgets_LIBRARIES, Qt6Widgets_INCLUDE_DIRS, Qt6Widgets_DEFINITIONS,
Qt6Widgets_COMPILE_DEFINITIONS, Qt6Widgets_PRIVATE_INCLUDE_DIRS.

These are deprecated and are only intended for easier porting from
Qt5 to Qt6. Qt consumers should instead rely on the Qt module targets
e.g target_link_libraries(app PRIVATE Qt6::Widgets)

Note that the variable contents includes transitive values for
everything except the _LIBRARIES variant. So Qt6Widgets_INCLUDE_DIRS
will contain values for Widgets, Gui and Core.

Qt6Widgets_LIBRARIES only contains a value like Qt6::Widgets, and when
that is used in target_link_libraries(), CMake will take care of the
transitivity.

3ac054d6a8 CMake: Re-work configure flags for CMake generators
Remove the -cmake-makefiles configure argument as its meaning was in
essence "do not pass a -G argument to CMake".
Instead, we add the following arguments:
    -cmake-generator <name> to pass -G <name> to CMake
    -cmake-use-default-generator to pass no -G argument to CMake

If none of those arguments is given, we try to autodetect the
generator. If a ninja executable is found, we prefer the Ninja
generator. On Unix we fall back to "Unix Makefiles".
On Windows, we do a poor man's compiler detection and select one of
"NMake Makefiles", "NMake Makefiles JOM" and "MinGW Makefiles".

While we're at it, implement some more translations than the sh

1048d83fc2 Limit OpenGL deprecation silencing on Apple platform to Qt itself
Apple deprecated the entire OpenGL API in favor of Metal, which
we are aware of, so we don't need to see the warnings when building
Qt.

Instead of applying the silencing globally for all Qt consumers,
both internal and external, we now limit the silencing to Qt itself.
That means user code that explicitly uses any of the deprecated APIs
will see the warnings. Note that this does not apply to merely using
any of the Qt OpenGL APIs. The user has to explicitly use the platform
APIs that have been deprecated.

The warnings need to be disabled on a build system level, so that
that they are passed as -D flags on the command line. If the defines
were done in Qt headers (qguiglobal.h e.g.), they would require the
user to always include this header before any of the Apple headers.

389c772fd4 CMake: Fix qconfig.cpp for cross-builds
This patch modifies the two preprocessor definitions
QT_CONFIGURE_HOSTBINDIR_TO_HOSTPREFIX_PATH and
QT_CONFIGURE_HOSTBINDIR_TO_EXTPREFIX_PATH which are exclusively used
by qmake (and not QtCore's QLibraryInfo) to determine the ext prefix
and the host prefix.

In the qmake build of Qt, qmake considers the host prefix as "location
where qmake is installed". This is usually the same as the ext prefix
but can be modified by the user at configure time.

In the CMake build, we don't build tools for the host but always for
the target platform. The QT_HOST_PATH is an external prefix we never
install to. That means, the qmake we build is always installed into
the ext prefix (CMAKE_STAGING_PREFIX or CMAKE_INSTALL_PREFIX).
Therefore, we can calculate the path of <ext_prefix>/bin relative to
<ext_prefix> and use this value for both,
QT_CONFIGURE_HOSTBINDIR_TO_HOSTPREFIX_PATH and
QT_CONFIGURE_HOSTBINDIR_TO_EXTPREFIX_PATH.

The "path of <ext_prefix>/bin relative to <ext_prefix>" is equivalent to
just the "path <prefix>/bin relative to <prefix>", meaning we can
safely use <prefix>, which is just CMAKE_INSTALL_PREFIX.

1685b0540d CMake: Fix top-level .prl file generation
Promotes qt_find_package()'d targets and their transitive dependency
targets to global scope. This will allow .prl file generation to
access targets in a sibling repo scope.

Retrofits qt_collect_libs() to be a bit more general, so it can be
reused both for prl lib collection, and traversing of dependencies
of qt_find_package() provided targets.

Removes the bail out checks for top-level static builds.

e932a898a5 CMake: Adjust some status messages about syncqt and file generation
Show a status message when we run syncqt for a module (gives a bit
more insight into why the configuration seems to stall for a moment).

Remove some uninformative messages about generating config.h files
and Depends headers, etc.

f3c7d22dd0 CMake: Don't use libraries in /usr/local by default on macOS
qmake builds of Qt don't use libraries in /usr/local because the
path is not considered a system path. Only the SDK path should be
used as a source of system libraries.

We should do the same for the CMake builds, which involves a couple of
things.

Tell CMake not to consider /usr/local (and a bunch of other
paths) as system prefix paths.

Disable pkg-config usage which by default is not used in qmake
Windows and macOS builds.

If a user wishes to use libraries located in /usr/local on macOS, they
can explicitly enable the behavior via -DFEATURE_pkg_config=ON.

In addition to enabling pkg-config, that will also disable the system
prefix modification described above.

Implementation notes

To disable pkg-config usage, we set an empty path for
PKG_CONFIG_EXECUTABLE, because there is no other good way. The
downside to this is that a lot of warning messages will be printed
that the pkg-config package can not be found.

The pkg-config feature needs to be computed in QtBuildInternals before
qtbase/src/configure.cmake, because it's too late to do it in that
file where a few qt_find_package calls already exist.
The feature value is also saved to QtBuildInternalsExtra, to make sure
that pkg-config is disabled whenever building another repo.

System prefix adjustment is done by removing paths from
CMAKE_SYSTEM_PREFIX_PATH.
Ideally we would remove also /usr as a path, to match what qmake does,
but that breaks find_program() calls for perl, python, etc.

We have to make sure that qt_find_package does not look in
PATH when looking for packages, which is the default behavior, because
PATH on macOS most likely contains /usr/local.

One last curiosity for future generations is that CMake 3.18+ has
merged a change to prioritise SDK locations over regular /usr/lib.

943340222e CMake: Generate qdevice.pri when cross-building
This adds the CMake equivalent to the classical -device-option key=value
configure argument:
-DQT_QMAKE_DEVICE_OPTIONS=key1=value1[;keyN=valueN]
The keys and values get dumped verbatim into qdevice.pri.

This patch also ports the machineTuple configure test. Its result is
written into qdevice.pri as value for the GCC_MACHINE_DUMP variable.

2299b61d0c CMake: Write gcc sysroot flags to qconfig.pri
For a cross-built, gcc-built Qt, the qmake build writes code into
qconfig.pri that adds the --sysroot flag to compiler and linker flags.
Follow suit in the CMake build.

To keep the diff small between the qmake-generated and CMake-generated
qconfig.pri files, the sysroot code is added at the top of
qconfig.pri, which is the reason for the new 'content' string variable.

projects can be cross-built against the cross-built Qt.

We also create wrapper scripts for the host qmake to save the user from
passing the -qtconf argument.
