b3b1e47378 CMake: Introduce qt_internal_add_app
This new function is meant to be used where load(qt_app) is used.

It delegates functionality to qt_add_executable, while handling
some additional behavior via a finalization function (mostly handling
of macOS Info.plist files and icons, as well as Windows icons and
resource files)

It uses a new PlatformAppInternal interface target.

9d55d6b45b CMake: Fix building debug apps with qmake on Windows
Our CMake build system only generated working .prl files for
the Release configuration in debug_and_release.

This caused a linking failure when building a Widgets example that
links against qtmain, specifically

qtmaind.lib(qtmain_win.cpp.obj) : error LNK2019: unresolved external
symbol __imp_CommandLineToArgvW referenced in function WinMain

The symbol is located in shell32.dll, which was not linked in, because
there was no qtmaind.prl file.

The fix to generate per config prl files is a bit complicated, because
add_custom_command does not support generator expressions in OUTPUT
and DEPENDS.

Instead we pre-generate 2 files per config, one with the preliminary
prl file content and another file that contains the final prl file
path (via generator expression).

Then we iterate over all configurations and create custom commands
with well known paths, and the final prl file is created by the script
called by the command.

7b9904849f CMake: Fix _nolink targets to be optional on the consumer side
On Windows, if Qt is built with Vulkan support but the user's machine
does not have Vulkan, it should still be possible to configure and
build an application (if the application does not use Vulkan of
course).

When Qt is built with qmake, the special windows_vulkan_sdk.prf file
makes sure not to export build time Vulkan include headers into the
generated .pri files. The same file also tries to find the include
headers via an environment variable. If it isn't set, it just adds a
bogus "/include" include path, which doesn't fail a user's application
build.

This wasn't the case for an application built with CMake, because the
exported Vulkan_nolink target uncodinitionally referenced Vulkan's
target properties. Which means that if the Vulkan package was not
found, the application failed to configure.

To mimic qmake's behavior, make sure to query the target properties
only if the Vulkan target exists, via the TARGET_EXISTS generator
expression.

Apply the same logic to all _nolink targets. This might not be
entirely correct in all cases, but we can revise this behavior later
after more feedback. At the very least it allows building non-Vulkan
based applications.

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.

It wasn't possible to create a cross, non-prefix build with

Fix this by comparing the qtbase build dir against

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.

Fixes the following qtdeclarative tests

 tst_qqmlinspector
 tst_qqmlenginedebuginspectorintegration

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.

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.

58a7e4f0bc CMake: Implement workaround for failing linux static builds
In static builds, due to our CMake design for auto-linking plugins
being incorrect we sometimes cause link failures on Linux in leaf
modules, because the link line order is incorrect.

So far such failures were fixed by explicitly modifying the order of
libraries on the link line in each failing CMake project.

This proves to be problematic because the failures appear in seemingly
random integrations that don't even touch the build system parts.

Until we fix the design, another less performant but more
general / safe way is to increase the link interface multiplicity,
which causes a cycle of libraries to be repeated more than 2 times
on the link line, thus giving the ld linker more chances to figure out
which symbols are needed for linking.

Implement this for Linux static builds to avoid random integration
failures for people that know nothing about this issue.

The link multiplicity for all qt modules is increased to 3, thus
QtGui would be repeated 3 times on the link line of each dependent
library. The value is also configurable via the
QT_LINK_CYCLE_MULTIPLICITY cache variable.

a7162704c8 CMake: Fix installation location of plugins in static builds of Qt
For static builds of Qt we installed the plugins into the lib
directory. However, they are expected in the plugins directory tree.

This happens, because we pass a value of an uninitialized variable to

and CMake defaults to "lib".

This flaw was introduced in b42feb02ce with the following intent:
"This patch also changes add_qt_plugin() to use the value provided in
INSTALL_DIRECTORY for ARCHIVE_INSTALL_DIRECTORY if no value is provided
for the latter."

The patch changed the value of arg_ARCHIVE_INSTALL_DIRECTORY but
missed to set the variable archive_install_directory, which is

We now directly set archive_install_directory and remove the unused
archive_install_directory_default variable.

2. A preliminary qt_lib_XXX_private.pri file is generated, containing

3. A custom command runs the QtGenerateLibPri.cmake script that combines

The same is done for mkspecs/qmodule.pri.

b56dc55c3a CMake: Fix qmake .depends info generated for module_private.pri files
Previously we checked the LINK_LIBRARIES property of the main module
target, but we should instead use the values of
INTERFACE_LINK_LIBRARIES set on the FooPrivate module.

Because both versionless targets and private targets are interface
libraries, we need to properly differentiate between them when
following versionless targets to their main associated target.

To do that, instead of using string comparison, export an additional
private _qt_is_versionless_target property, and query that.

Also make sure to set and export the _qt_config_module_name property
on the FooPrivate targets.

Also make sure to APPEND to EXPORT_PROPERTIES rather than override
(looking at you QtFeature.cmake).

4b23baddd3 CMake: Write QT.XXX.depends entries into module pri files
Qt module targets now export the "_qt_config_module_name" property,
which contains the module's name in qmake land. This can be different
from the lower case target name (e.g. Test vs testlib). This exported
property is used when retrieving the dependencies of a module outside
of qtbase.

The property's name is a bit odd and lower case, because we want to be
able to set it on INTERFACE_LIBRARY targets, for instance header
modules. This CMake pecularity is described in
https://gitlab.kitware.com/cmake/cmake/issues/19261

f240d94f14 CMake: Install non-main-config tools and executables to a subdir
When using Ninja Multi-Config, we don't want to install a "Release"
moc.exe, and then override it with a "Debug" moc.exe.

Because it doesn't seem possible to exclude installation of targets
per configuration, put the non-main configuration tools into
configuration specific subfolders like "bin/Debug", so no overriding
happens upon installation.

Introduce a new function qt_get_install_target_default_args() which
returns install destination arguments for consumption in qt_install()
calls. The function adds the config-specific suffix to the destination
for the appropriate configs.

Each call to qt_install *adds* new rules for installation,
which means that export registration needs to happen only on the first
call.

Make sure qt_add_tool doesn't ask qt_add_executable to install
yet again, to create duplicate rules.

Apply the same install arguments logic to qt_add_executable calls.

bf315c5526 CMake: Make build system of installed Qt more relocatable
Aka handle CMAKE_INSTALL_PREFIX in a more relocatable way.

The following story inspired this change.

If a user wants to build a Qt repo into a different install prefix
than the usual Qt one, this will fail configuration because we
look for various things like syncqt, qdoc, etc relative to
CMAKE_INSTALL_PREFIX, which will now point to a different location
where none of the above tools are located.

The intent for such a use case is to support building Qt packages with
Conan, which sets a random install prefix when configuring a repo.

The idea is to derive the qt prefix dynamically from the
QtBuildInternals package location. Essentially it's a reverse relative
path from the QtBuildInternalsConfig.cmake file to the install prefix
that was specified when initially configuring qtbase.

Once the dynamic prefix is computed (so we know where the possibly
relocated Qt is), we can find tools like syncqt and qdoc.

This is an initial attempt to support a use case like that.

More design work will probably needed in case if tools / libs need to
be found in a location different than the Qt install prefix (so
support for multiple install prefixes / search paths).

An example of such a case would be when building qtdeclarative and
qtquickcontrols2 as Conan packages in one go. Most likely the
qmltyperegistrar tool will be located in the random install prefix
set by Conan, so building qtquickcontrols2 might fail due to not
finding the tool in the original Qt install prefix.

As to the implementation details, the change does the following:
- Dynamically computes and sets the
  QT_BUILD_INTERNALS_RELOCATABLE_INSTALL_PREFIX variable when
  find_package()'ing QtBuildInternals. It's an absolute path
  pointing to where the relocated Qt is.

- When building qtbase this variable is not yet available (due
  to QtBuildInternalsExtra not existing), in that case we set
  the variable to the absolute path of CMAKE_INSTALL_PREFIX
  (but only for the initial qtbase configuration).

- Remove QT_BUILD_INTERNALS_ORIGINAL_INSTALL_PREFIX which was used
  for standalone tests purposes. It's not needed now that we compute
  the location of the Qt prefix dynamically.

- The Unixy qt-cmake and qt-cmake-private shell scripts now
  use a relative path to find the toolchain file we created.

- The toolchain file also dynamically computes the location of the Qt
  packages, and adds them to CMAKE_PREFIX_PATH.

- A lot of existing CMAKE_INSTALL_PREFIX uses are replaced with
  QT_BUILD_INTERNALS_RELOCATABLE_INSTALL_PREFIX. This includes finding
  tool locations, mkspecs dir, path environment setup for tools, etc.

- Some places still use CMAKE_PREFIX_PATH in the following cases
  - When determining paths while configuring qtbase (valid cases)
  - When I wasn't sure what the behavior should be, so I left them
    as-is (an example is documentation generation, do we want to
    install it into the random Conan prefix, or into the main prefix?
    Currently it installs in the random prefix).

Note that relocating a Qt installation does not work for non-prefix /
non-installed builds, due to hardcoded paths to include directories
and libraries in generated FooTargets.cmake files.

8ddd3ee60b Revert "CMake: qt_find_package() enable debug behavior by default"
It broke configuration of qtwayland standalone tests, due to qtwayland
doing 3 separate qt_find_package(Wayland) calls with the same package
but different arguments in 3 different directory scopes.

The top scope didn't have PROVIDED_TARGETS argument. The rest of the
scopes did have the arguments with either Server or Client, but because
of the debug behavior above being enabled by default the dependencies
weren't registered in the Qt6WaylandClientDependencies.cmake file (and
the server equivalent).

The registration didn't happen due to the skipping logic, when a package
is found and the targets already exist.

This led to standalone tests failing to configure because they tried
linking against non-existent Wayland::Client and Wayland::Server
targets.

This reverts commit dd7e40b108.
