2746051522 CMake: Disconnect docs installation targets from generation targets
"ninja install_docs" should not run the "docs" target, because with
the usual workflow
    ninja docs
    ninja install_docs
the documentation would be built twice.

That of course means that "ninja install_docs" will fail if "ninja
docs" wasn't run before.

Analogous for html_docs, qch_docs, the repository-level and
module-level documentation targets.

db939d8f33 CMake: Fix top-level documentation install targets
The following targets did not do any actual installation:
install_docs, install_html_docs, install_qch_docs,
plus their repository-level counterparts.

Add the following dependencies:

install_html_docs
    --> install_html_docs_<repo>
        --> install_html_docs_<module>

Analogous for qch.

The install_docs target already triggers install_html_docs and
install_qch_docs. Analogous for install_docs_<repo>.

ca59c20939 CMake: Fix usage of cache variables in qt.toolchain.cmake
We have some cache variables that are used in our qt.toolchain.cmake
toolchain file, for example QT_CHAINLOAD_TOOLCHAIN_FILE. When CMake
runs a configure test with try_compile, our toolchain file is included
again, but only a restricted set of variables is available.

Add the variables that are used in our internal toolchain file to
CMAKE_TRY_COMPILE_PLATFORM_VARIABLES. This makes them visible for
try_compile calls operating on source files.

Also pass the variables via the environment to support try_compile
calls that operate on whole projects.

72aab8b487 CMake: Bump the minimum required CMake version to build Qt to 3.18
Add a new function that returns the minimum CMake version required to
build Qt. Pass that value to cmake_minimum_required() when building
qtbase and its standalone tests.

The minimum supported CMake version is read from qtbase/.cmake.conf
and its value should be updated when the need arises. It's the main
source of truth for all repos.

Provide a way to lower the minimum CMake version at configure time by
passing a value via QT_FORCE_MIN_CMAKE_VERSION.
This is not an officially supported way of building Qt. If the
specified version is lower than Qt's supported minimum, show a
warning.

Nevertheless the option is useful for testing how Qt builds with a
different minimum CMake version due to different policies being
enabled by default.

Issue warnings for CMake versions that are higher than the minimum
version but are known to cause issues when building Qt.

A counterpart change is needed in qt5 to ensure the minimum CMake
version is set at the proper time for top-level builds.

Ideally we would use the same 'check the CMake minimum version` code
in all our repositories, but that will cause lots of duplication because
we can't really find_package() the code and doing something like
include(../qtbase/foo.cmake) hardcodes assumptions about repo
locations.

So for now we don't bump the minimum version in child repo
cmake_minimum_required calls (qtsvg, qtdeclarative, etc).
Instead we record both the minimum supported version and the computed
minimum version (in case a different version was forced) in
QtBuildInternalsExtra.cmake.
Then we require qtbase's computed min version in
qt_build_repo_begin().

This won't set policies as cmake_minimum_required would, but at least
it propagates what minimum CMake version should be used for child
repos.

We might still have to bump the versions in child repos at some point.

b54dd671aa CMake: Bump the minimum required CMake version to use Qt to 3.14
At the moment our examples require a minimum of 3.14 due to changes
in upstream CMake's Autogen functionatlity to support Qt 6. Anything
lower would simply not work with Qt 6.

It's not clear yet if we actually want to require 3.14, or something
higher. At the very least there were many significant changes to
support iOS in CMake 3.15.

But for now just bump the version checked by Qt6Config.cmake to be
consistent with what's in our examples.

the unknown parameter "/INCREMENTAL:NO" and output a lot of warning

The situation is a lot more worse when we are using clang-cl.

file named "/INCREMENTAL:NO" and just stop compiling. It seems
clang-cl treat unknown parameters as input files.

53b11882c8 CMake: Cleanup module and plugin define situation
The QT.<module>.DEFINES assignment in pri files needs to take into
account the module name when computing the define name. This is the
MODULE value that qmake specifies.
In CMake that would be the value of CONFIG_MODULE_NAME.

Previously the value of the define was computed in
qt_internal_module_info() without taking into account the module name.

While qt_internal_module_info() ended being used also for plugins and
other target types, the defines computed by it were meant to be used
only for Qt modules.
Thus remove the <result>_define assignment from
qt_internal_module_info and move its computation directly into
qt_internal_add_module, taking into account the value of
CONFIG_MODULE_NAME.

The only other use of module_define was in qt_internal_add_plugin but
that was merely a long overdue copy-paste error, qmake doesn't
propagate QT_FOO_LIB defines for plugins.

As result, a define special case in testlib is not needed anymore,
because the define is now computed properly.

Finally, QT_FOO_LIB should not be used while building the Qt module
itself, so instead of using PUBLIC_DEFINES option of
qt_internal_extend_target, use target_compile_definitions(INTERFACE)
directly.

da1854c683 CMake: Re-work documentation targets
The top-level prepare_docs target is supposed to run before the
generate_docs target.

The repository-level targets like prepare_docs_qtbase now also run
before their respective generate targets.

To achieve that, several intermediate targets had to be introduced.
The dependencies for top-level generate_docs look like this:

              /--> generate_top_level_docs_Core --\
generate_docs ---> generate_top_level_docs_Gui  -----> prepare_docs
              \--> ...                          --/

The dependencies for repo-level generate_docs_<repo> look like this:

                     /--> generate_repo_docs_Core
generate_docs_qtbase ---> generate_repo_docs_Gui
                     \--> ...

generate_repo_docs_Core --\
generate_repo_docs_Gui  -----> prepare_docs_qtbase
...                     --/

Analoguous for qch_docs.

And last but not least, the module-level generate_docs_<module> depends
on prepare_docs_<module>, just like before.

The strangely named top-level install targets have been renamed to
install_html_docs, install_qch_docs and install_docs.

The html_docs target is now merely an alias for generate_docs.

Apart from prepare_docs, the top-level targets do not depend on the
repository-level targets anymore. Targets that are just an alias (docs,
install_docs, ...) have been re-defined to depend just on the respective
top-level targets.

bcc7d34540 CMake: Provide a qt-internal-configure-tests script
This is meant to be called by our CI instructions to build standalone
tests of a Qt repository.

Currently it just calls qt-cmake with
-DQT_BUILD_STANDALONE_TESTS=ON, but it might contain more things in
the future.

The script also simplifies configuring standalone tests locally, due
to not having to remember the name of the magical variable.

Change our CI instructions to use the new script.

1b4ea4a1d8 CMake: Fix target dependency cycle regarding qpa plugins in qtwayland
With the introduction of the new 'default_qpa_plugins' custom target,
a target dependency cycle occurred in qtwayland:
qtwaylandscanner -> default_qpa_plugins -> a wayland qpa plugin ->
WaylandClient -> qtwaylandscanner

The issue is twofold:
- default_qpa_plugins accidentally depended on non-qpa plugins.
- All qpa plugins were enabled by default, including the wayland ones.

Fix the default_qpa_plugins target not to depend on regular non-qpa
plugins.

Also fix qpa plugins not to be enabled by default, but instead only
choose one qpa plugin to be the default (via evaluating the
DEFAULT_IF) condition.

5fa823491b CMake: Fix automatic sysrootification detection for qmake
The way we detected whether SysrootifyPrefix needs to be set was
incorrect.

We checked if extprefix == prefix => SysrootifyPrefix should be
true. But that was previously always the case for a non-prefix build,
which means it was not possible to build apps (due to qmake expecting
to find include dirs in the sysroot, despite the non-prefix Qt not
being installed anywhere into the sysroot).

Instead we should do what qmake does. Only set SysrootifyPrefix to
true if extprefix was not provided and a sysroot is available.

To make it work for iOS and Android, the sysroot detection code had to
be moved earlier than the SysrootifyPrefix detection.

4bf8f70bfe CMake: Let doc targets depend on doc tools in top-level build
For top-level builds it's desirable to have "ninja generate_docs" build
all tools needed to generate the documentation.

This is problematic since the doc-generating targets are created before
the doc tool targets. Thus, we must defer the dependency connection if
the doc tool target is not yet available.

This patch adds the functions qt_internal_defer_dependency and
qt_internal_add_deferred_dependencies.

7c23281db3 CMake: Fix headersclean to work on macOS
It appears there's a difference between the chosen macOS compiler path
in the CI versus the compiler path on my local machine.

In the CI the chosen compiler path ends up 'being /usr/bin/clang++'
whereas for me locally it's

/Applications/Xcode.app/Contents/Developer/Toolchains/XcodeDefault.xctoolchain/usr/bin/c++

For some reason the headersclean commands succeed in the CI, but
locally they fail for me saying that standard library includes can not
be found, unless an explicit sysroot flag is specified.

I assume that in the CI the '/usr/bin/clang++' compiler shim chooses some
implcit sysroot, whereas the longer Xcode compiler expects an explicit
sysroot.
It's probably also affected by the fact that in the CI we pass an
explicit CMAKE_OSX_SYSROOT to a non-standard Xcode location e.g.

/Applications/Xcode11.app/Contents/Developer/Platforms/MacOSX.platform/Developer/SDKs/MacOSX10.15.sdk

Note the '11' in the Xcode app name.

Locally I don't pass a custom CMAKE_OSX_SYSROOT, and my Xcode is
installed in a regular location e.g /Applications/Xcode.app.

The sysroot flag and path is added to regular CXX compilation rules
inside CMake's core (in cmLocalGenerator.cxx).

Reuse the same variables that CMake uses and add them to our headersclean
command rules.

 - TARGET_EXPORT_NAMES containing the target names as they appear in the

Operations that require actual targets are run on the TARGETS, in the
additional target info file only TARGET_EXPORT_NAMES are written.

This distinction is required for the case where the host Qt lacks a
tool that is built in the target Qt.

Example: host Qt is built with DEVELOPER_BUILD=OFF, target Qt is built
with DEVELOPER_BUILD=ON. Then the host Qt lacks qmljs, but it is built
in the target Qt. TARGETS contains qmljs_native, and
TARGET_EXPORT_NAMES contains qmljs.

1e1805ed36 CMake: Workaround iOS Xcode issue when configuring app
It appears that CMake's Xcode generator default behavior can't really
handle imported object libraries location, which Qt uses extensively
(all the qt_add_resource calls).

Specifically the project fails to configure with the following error
message:
The OBJECT library type may not be used for IMPORTED libraries under
Xcode with multiple architectures.

An issue was filed upstream at
https://gitlab.kitware.com/cmake/cmake/-/issues/21276

In the mean time, it looks like it's possible to work around the issue
by setting XCODE_EMIT_EFFECTIVE_PLATFORM_NAME global property to OFF.
This needs to be done before the very first project() call, so we do
it in the generated Qt toolchain file.

Note that the workaround only works if the CMake project is configured
with a single architecture given to CMAKE_OSX_ARCHITECTURES.
If multiple arches are given, it will fail with the same error
message.

This will add automatic linkage of WinMain to executables marked with

As well as the addition of the '-Wl,-e,_qt_main_wrapper' linker flag

moment, windeployqt is still querying qmake for these information. For a
cross compiled Qt, the proper target mkspec has to be set in this case.

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.

07b6d3367d CMake: Refactor optimization flag handling and add optimize_full
Introduce a bunch of helper functions to manipulate compiler
flags and linker flags for the
CMAKE_<LANG>_FLAGS_<CONFIG>
and
CMAKE_<LINK_TYPE>_LINKER_FLAGS_<CONFIG>
CMake variables.
These variables can be assigned and modified either in the cache
or for a specific subdirectory scope, which will apply the flags
only to targets in that scope.

Add qt_internal_add_optimize_full_flags() function which mimics
qmake's CONFIG += optimize_full behavior.

Calling it will force usage of the '-O3' optimization flag on supported
platforms (falling back '-O2' where not supported).

Use the function for the Core and Gui subdirectories, to enable full
optimization for the respective Qt modules as it is done in the qmake
projects.

To ensure that the global qmake-like compiler flags are assigned
eveywhere,
qt_internal_set_up_config_optimizations_like_in_qmake() needs
to be called after Qt global features like optimize_size and
optimize_full are available.

This means that qtbase and its standalone tests need some special
handling in regards to when to call that function.

7bb91398f2 CMake: Allow finding Qt CMake packages in additional locations
By default, when using the Qt6 CMake package to look for components,
the find_package() calls for the components use NO_DEFAULT_PATH to
ensure that CMake doesn't accidentally find system (distro) packages.
Instead we limit the paths to one level up from where the Qt6 package
is.

Unfortunately that doesn't quite work for finding Qt packages that
might have been installed into a different prefix than where the main
Qt prefix is.
This happens when Qt addons are built by Conan, and installed into
a separate prefix.

To allow calls like find_package(Qt6 COMPONENTS ConanAddon) to work
in a scenario as described above, introduce a new variable called
QT_ADDITIONAL_PACKAGES_PREFIX_PATH which can be used to specify
additional paths where Qt CMake packages should be found.

This is similar to previously introduced QT_EXAMPLES_CMAKE_PREFIX_PATH
variable which was meant for a similar case, but only for examples.

Additionally, allow disabling the NO_DEFAULT_PATH option by setting
the QT_DISABLE_NO_DEFAULT_PATH_IN_QT_PACKAGES cache variable to TRUE.
This would allow regular usage of CMAKE_PREFIX_PATH to work, at the
risk that system Qt CMake packages might be found.

User projects built with an unknown
configuration (CMAKE_BUILD_TYPE=ArbitraryName) will link against a

Consider a Qt module with a 3rdparty library target in
PRIVATE_MODULE_INTERFACE, e.g. XKB::XKB in Qt6::GuiPrivate. Consumers of
GuiPrivate automatically depend on XKB::XKB. In order to do that they
must find_package(XKB ...). As all find_package calls for GuiPrivate are
in the same place as the ones for Gui, this package must be marked as
optional. Otherwise all consumers of Qt6::Gui would have to have the
xkbcommon package installed too.

This patch exports find_package calls for every 3rdparty public
dependency of private modules and marks them as optional.

25cc901f04 CMake: Fix configure -redo for top-level builds
When re-doing in a top-level build, we did not read the config.opt file
from the top-level directory.

Also, the config.opt file should not contain the -top-level argument.
This is an internal option, and on Windows, it was already missing. The
information whether we're doing a top-level build is now passed in the
CMake variable TOP_LEVEL.

93fc3afe71 CMake: Check that QT_HOST_PATH is set when using the Qt toolchain
If a consumer wants to cross-compile a Qt app, they need to provide
the host Qt path location.

When building Qt in the CI we embed the Qt host path into the
generated CMake toolchain file for convenient building of other Qt
modules.

But once Qt is built, packaged and installed on a user's machine, most
likely the Qt host path will not be the same. In such a case, if the
user wants to use the convenience toolchain, they should explicitly
provide the Qt host path via the QT_HOST_PATH and
QT_HOST_PATH_CMAKE_DIR variables.

Show an error message if the values are not provided or don't exist
on the file system.

It's possible that in the future the Qt installer will patch the
toolchain file, or provide additional info, to point to the host
Qt installation so that the user doesn't have to do it manually.

But until that's done, a friendly error message is a good way to
inform the user what they should do.

67567b8e0d CMake: Conditionally set compiler in generated toolchain file
Public consumers of the qt toolchain file will most likely not have
their compilers in the same location where they were on the Qt build
machine.

Only set the compiler paths if none was set already, and the paths
actually exist.

This seems to become a trend in the generated toolchain file, and is
only a stop-gap solution.

A proper solution (two different toolchain files) may follow.

46f8c46bee CMake: Teach QtProcessConfigureArgs.cmake to configure other modules
Until now, QtProcessConfigureArgs.cmake could only handle qtbase and the
top-level build. Add the variable MODULE_ROOT that the user can point to
the module that is to be configured.

Example - QtDeclarative can now be configured like this:

cd qtdeclarative-build-dir
echo -qml-network > config.opt
cmake -DOPTFILE=config.opt -DMODULE_ROOT=<source-root>/qtdeclarative \
    -DCMAKE_COMMAND=<install-prefix>/bin/qt-cmake-private \
    -P <source-root>/qtbase/cmake/QtProcessConfigureArgs.cmake

A convenience script that saves the user from entering this unwieldy
incantation will be added in a subsequent commit.

C4180, C4458 were disabled already in 2012, in commit 6668f5becf.
C4577 was disabled due to QtScript being compiled without exception

Anyhow, Qt Script is now officially gone in Qt 6, and Qt headers
do work just fine with C4180. Finally, C4458 is nowadays a W4 warning,
so not enabled in the first place.

db21bad936 Port headersclean check to CMake
Configure Qt with -DQT_FEATURE_headersclean=ON to enable the
check. There will be separate target for each module include
(e.g. QtCore_header_check), but the check will also be done
when the module is built for the first time.

There are notable differences to the qmake version:
- the build does not pick up anymore default defines or flags from
  the module, or Qt. Instead options like -fPIC they have to be listed
  explicitly. Also for this reason, we have to skip the vulkan-related
  headers from the check, since vulkan/vulkan.h is not necessarily
  in the compiler's default search path.
- some checks for nowadays unsupported compiler versions are
  removed.
- -Wdouble-promotion -Wshorten-64-to-32 is not added for clang
  builds; the qmake code path did never enforce that on CI
  machines (it was non-Apple clang only), and the check currently
  fails on these configurations.

cb1600145b CMake: Adjust compiler flag optimizations to qmake mkspec ones
There are inconsistencies in the default optimization flags added by
CMake across configurations like Release and RelWithDebInfo.
In particular Release uses -O3, whereas RelWithDebInfo uses -O2,
as well as usage of /INCREMENTAL in release configs with MSVC, etc.

To make sure that the Qt 6 binaries built with CMake are consistent
across configs, as well as consistent with the flags we used when
building Qt 5 with qmake, add a horrible search and replace mechanism
to replaces the CMake flags with what our mkspecs indicate to use.

Ideally this would be done by providing custom CMake toolchain files
for each platform we support, and we might revisit that later if the
need really arises.

To implement the replacing, we first need the flags that should be
added. Port the QMAKE_CFLAGS_OPTIMIZE variables to CMake, which is
done in QtCompilerOptimization.cmake.

Then a new function called
qt_internal_set_up_config_optimizations_like_in_qmake will look for
any kind of optimization flags set in the
CMAKE_<LANG>_FLAGS_<CONFIG> style variables, remove them, and add
the appropriate flags that qmake mkspecs provide.

On some platforms (like Windows MSVC) the function also alters the
linker CMAKE_${TYPE}_LINKER_FLAGS_<CONFIG> style variables.

The mechanism allows opting out of this replacing by
setting the QT_USE_DEFAULT_CMAKE_OPTIMIZATION_FLAGS value.

It also allows opting into removal of flags for custom configs by
providing QT_ADDITIONAL_OPTIMIZATION_FLAG_CONFIGS. It's only removal,
because we wouldn't know what kind of config it is, and thus what
flags to add.

The currently modified configs are: Release, RelWithDebInfo,
MinSizeRel, Debug aka the usual default CMake provided ones.

The mechanism is only applied to C-like languages.
ASM is not handled to be on the safe side due to not knowing what kind
of compiler flags the platform assembler might take.
It's also important to skip RC on MSVC platforms.

calls and written it into commandline.cmake files.

We extend QtProcessConfigureArgs.cmake to pick up those commandline.cmake
files to feed our command line handling code, which is a
re-implementation of the command line handling in qt_configure.prf.

The command line handler sets INPUT_xxx variables, similar to
configure/qmake's config.input.xxx variables. The INPUT_xxx values are
translated
- to -DFEATURE_xxx=ON/OFF arguments if the input represents a feature,
- to corresponding CMake variables if such a variable is known,
- or to -DINPUT_xxx=yyy CMake arguments.

Configure arguments that have an entry in
cmake/configure-cmake-mapping.md are actually implemented. Other
arguments are likely to need more work.

32121e9882 CMake: Split out some Android functions into a public API file
To fix CMake Qt For Android projects to configure, we need to move
some functions from a private CMake API file only, to a public one.

Add Qt6AndroidMacros.cmake which will be loaded by Qt6Core package.

We'll have to decide how we proceed with Qt5AndroidSupport.cmake,
because that file automatically runs code when included in Qt5, and we
usually don't want to do it.

We'll also have to decide how to handle the define_property() calls
that are still left in the private QtPlatformAndroid.cmake file.

With this fix, Qt example CMake projects that use
add_qt_gui_executable should now be buildable. An APK can be created
with 'ninja apk'.

Unfortunately Qt Creator 4.13 does not currently seem to support
opening and building CMake Qt For Android projects properly.
While the build succeeds after fiddling with the Kit settings, the APK
deploy step fails to run (at least on my machine).

So the simplest way to run the built APK is to open the android-build
dir with Android Studio and launch the example application from there.
