ce9efcf4a9 CMake: Fix QT_STAGING_PREFIX for repos other than qtbase
For repositories other than qtbase the QT_STAGING_PREFIX was empty,
because it was only determined in qtbase.

Also, we save the CMAKE_STAGING_PREFIX in the Qt6BuildInternals package
and set this variable if it's not explicitly set by the user.
As with CMAKE_INSTALL_PREFIX this behavior can be prevented by defining
QT_BUILD_INTERNALS_NO_FORCE_SET_STAGING_PREFIX=ON.

60d72b7ab6 CMake: Fix incorrect SIMD arch_haswell and avx profile conditions
Fix the conditions in qt_add_simd_part for arch_haswell and the
avx512 profiles to mimic what simd.prf does.

Add missing SIMD flags in QtCompilerOptimization for arch_haswell.

Compute the compile flags for the avx512 profiles from the
profile dependencies.

Remove the special case in Gui that hardcoded the compilation of
qdrawhelper_avx2.cpp to be conditional on avx2 being enabled
instead of arch_haswell. The Gui project already has another
qt_add_simd_part that is enabled if arch_haswell is enabled, which
will now work correctly due to the fixes in qt_add_simd_part.

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.

062318feb2 CMake: Fix non-prefix build detection when CMAKE_STAGING_PREFIX is set
It wasn't possible to create a cross, non-prefix build with
CMAKE_INSTALL_PREFIX set to something else but the qtbase build dir
and CMAKE_STAGING_PREFIX set to the qtbase build dir.
This would be equivalent to
    configure -prefix /usr \
              -extprefix ~/my/qtbase/build/dir

Fix this by comparing the qtbase build dir against
CMAKE_STAGING_PREFIX if it is set. We also have to adjust the
QT_BUILD_DIR variable in a similar way.

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.

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.

3ef14c8943 CMake: Fix framework handling for .pri files
Rather than embedding the full absolute path to the framework, we
should instead write a -framework Foo flag.

qmake seems to do this by specifying QMAKE_LIBS_FOO in the mkspec.
We'll try to get away with just deriving the name of the framework
from the path, to avoid having to introduce a mkspec equivalent
mapping for CMake.

This doesn't currently handle framework include paths, which qmake
also handled by harcoding QMAKE_INCDIR_FOO in the mkspec, and then
sysrootifying it via mkspecs/common/mac/sdk.prf.
Hopefully that's not really needed, given that -framework flag
should imply include paths as well.

d7efb2a419 CMake: Fix include paths for AUTOMOC when using frameworks
The qml app was crashing when used by qtdeclarative auto tests. It
complained about unregistered QML types. qmltyperegistrar didn't
create registration info for these types. moc didn't output class info
about these types because the build system didn't provide the proper
include paths.

In qmake land, moc was given 2 sets of paths when building a module:
the non-installed framework dirs as -F flags, and also the
$repo_build_dir/include paths as regular -I flags.

In CMake land we only gave include paths to the non-installed
framework dirs as -I flags, not -F flags.
That's because AUTOMOC checks for a specific pattern in the include
paths to transform them into framework include paths
(existence of Foo.Framework/Headers symlink),
and we didn't pass such an include path.

Make sure to mimic what qmake does, and pass -I flags to
$repo_build_dir/include as public include paths, but only via
BUILD_INTERFACE aka when building Qt itself.

Also pass -F flags by specifying framework include paths in the
pattern that AUTOMOC expects.

06557312d2 CMake: Improve .prl dependency tracking
Previously .prl files were created via add_custom_command with a
POST_BUILD command. This means they were only created after linking
the libraries, and that whenever a relinking happened, dependees had
to rebuild many parts of their target.

Ideally we would use generator expressions in the OUTPUT argument, but
versions up-to CMake 3.18 don't support doing that.

A workaround is to create and depend on a .prl file name without
generator expressions, and as a side effect also create a .prl file
that does use generator expressions, but don't specify it as an
OUTPUT.

This seems to work well, and improves the dependency tracking issue,
at the cost of one more file copy per .prl file whenever it changes.

d2a04cf165 CMake: Fix .prl generation and installation for plugins
The referenced Qt libraries had paths to the build directory, instead
of the $$[QT_INSTALL_LIBS]/ prefix. The reason was two-fold:

1. QT_BUILD_LIBDIR had the wrong value, namely
"${QT_BUILD_DIR}/platforms/qfoo".

2. The QtFinishPrlFile.cmake script was called with a wrong OUT_FILE
parameter, placing the final .prl file in the build lib dir.

As drive-by change, surround arguments for QtFinishPrlFile.cmake that
can contain spaces with double quotes.
This amends 8c8c0f65e3.

4ab5432081 CMake: Write object libs of Qt resources to .prl files
Since commit e343affd63 we're creating object libraries for Qt
resources in static libraries. Those must be reflected in the
generated .prl files for static builds of Qt.

In qt_add_resource, we now calculate the install locations of the
object files of rcc-generated C++ files and save them in the target
property QT_RCC_OBJECTS. This property is then passed to
QtFinishPrlFile to write the object file paths to the .prl file.

f626c73b28 CMake: Fix many failing qtdeclarative MinGW tests
A lot of qtdeclarative tests fail due to not finding the
QtTest qml plugin in ${prefix}/qml. This is just the symptom, the
problem is that the combination of CMake + MinGW + Qt relocatability
behaves incorrectly.

The value returned by
QLibraryInfo::location(QLibraryInfo::Qml2ImportsPath) for the
qmltestrunner executable is ${prefix}/bin/qml which is incorrect.

This happens due to a combination of things. The
c33916a279 change in qtbase introduced
checks to figure out whether an application is a windeployqt-ed app
to adjust the prefix path.

This check tries to find the import library libQt6Core.a in the lib
subfolder whenever the executed app dir path is equal to the
computed prefix path.

If it's found, the code assumes we are running a tool in
${prefix}/bin. If it's not found, the code assumes it's a
windeployqt'ed app, where the Qt .dlls are next to the executable.

Currently when QtCore is built with CMake targeting MinGW, we actually
create a libQt6Core.dll file instead of a Qt6Core.dll file, and also
an import library called libQt6Core.dll.a, instead of libQt6Core.a.

The prefix check code actually prepends an additional "lib", thus
trying to find the liblibQt6Core.a import library.

This fails, the code assumes a windeployqt'ed app, and returns the
currently executed app path dir as the prefix aka ${prefix}/bin in
the case of qmltestrunner, and thus none of the qml plugins are found.

To fix this, generated the shared library and the import library names
as qmake expects them, aka Qt6Core.dll and libQt6Core.a.

Some of this renaming was done for MinGW plugins and shared libraries,
but not for modules in 9b0e23ef8a.

Extract the duplicate code and apply it to all shared libraries built
by Qt on Windows. Adjust the prefix and suffix accordingly, depending
on whether we use MinGW or not.
