Previously, this was only supported when cross-compiling, but that's an
unnecessary limitation. Instead, make it possible to build the "host"
tools (notably qmake) even when they've been found elsewhere due to
QT_FORCE_FIND_TOOLS=ON and a supplied QT_HOST_PATH.
The combination of QT_FORCE_FIND_TOOLS and QT_FORCE_BUILD_TOOLS set to
ON is useful for developers who touch content that ends up in the
bootstrap library.
QT_BUILD_TOOLS_WHEN_CROSSCOMPILING is deprecated in favor of
QT_FORCE_BUILD_TOOLS.
[ChangeLog][CMake] QT_BUILD_TOOLS_WHEN_CROSSCOMPILING has been
deprecated in favor of QT_FORCE_BUILD_TOOLS. The latter can be used in
combination with QT_FORCE_FIND_TOOLS and QT_HOST_PATH to use tools from

Previously if
-extprefix /tmp/sysroot (CMAKE_STAGING_PREFIX)
-developer-build (FEATURE_developer_build)
were specified, but
-prefix (CMAKE_INSTALL_PREFIX)
was not,
the build system would set the CMAKE_INSTALL_PREFIX to the
qtbase build dir.
Then, if targeting desktop, this would be considered a non-prefix
build (ninja install would refuse to work), whereas in a cross-build
it would be considered an installable build.
In both cases though, the rpath of installed binaries would point to
the qtbase build dir (because CMAKE_INSTALL_PREFIX would be set to the
qtbase build dir).
This is quite confusing behavior, in more than one way.
Change the build system to consider that an explicit -extprefix should
cause Qt to always be installed, even if -developer-build is
specified.
This means the installed rpaths and on-device install prefix
(CMAKE_INSTALL_PREFIX) will now use the default computed install
prefix, e.g. /usr/local/Qt
It also means that to get a non-installable developer + custom staging
and install (on-device) prefix build, users will have to be explicit
and set all the options
-extprefix ~/qt/qtbase_build_dir
-prefix /usr
-developer-build

CMake will put the Qt libraries in the qtbase build dir, ninja install

the Qt libraries are expected to be in /usr.
Support for this scenario was originally added for cross-builds in
062318feb2 , but not desktop builds.
Such a build is useful when you want to have install rpaths different
from where Qt is initially installed to (the staging prefix).
This case doesn't really happen often when targeting desktop
platforms, it's mostly used for cross-compilation (e.g yocto).
Being able to have the same setup with a desktop build is nevertheless

Introduce a new -no-prefix option that can be used to build Qt without
having to install it.
Currently, -no-prefix is already implied by -developer-build, but
-developer-build also implies -warnings-are-errors and
-feature-private-tests, which not everyone might want to use.
Some Qt builders likely use -developer-build for the no-prefix
behavior, hence we introduce a standalone -no-prefix option to offer
a nicer user experience without -Werror and friends.
Previously it was possible to achieve the same by specifying
-prefix $PWD, but that relies on $PWD expanding property in the used
shell.
The new -no-prefix doesn't depend on the type of the shell and
is shorter to type.
Internally this gets passed by configure as -DINPUT_no_prefix=yes to
CMake, and transformed into a -DQT_FEATURE_no_prefix=ON feature.
The feature also gets automatically auto-detected to ON if
developer-build is set, -prefix is either unset or $PWD.
CMake code should still query QT_WILL_INSTALL to decide whether
files need to be installed or not.
As a drive-by, we now also export QT_FEATURE_developer_build to
be available for querying during configuration of other repos
(previously it was only possible to query FEATURE_developer_build).

- install examples as part of main make install step, rather than

- adjust CXX flags when building with MSVC to ensure we can still

While trying to implement the 'host artifact reuse' Coin instructions
change, a bug surfaced where the qemu configurations didn't find
the host tools and instead tried to use the cross-compiled tools
while building qtbase, which failed due to not finding the
runtime linker (another unsolved issue).
Before the host artifact reuse change, the host tools were found
successfully.
The difference that caused the issue is that the target install prefix
was a direct subfolder of the host prefix.
host - /home/qt/work/qt/install
target - /home/qt/work/qt/install/target
Before the host reuse change the install prefixes were as follows
host - /home/qt/work/qt/install/host
target - /home/qt/work/qt/install/target
While looking for the Qt6CoreTools package, we temporarily set
CMAKE_FIND_ROOT_PATH and CMAKE_PREFIX_PATH to contain first
'/home/qt/work/qt/install' and then '/home/qt/work/qt/install/target'.
CMake then reroots the CMAKE_PREFIX_PATH values onto values in
CMAKE_FIND_ROOT_PATH, making an MxN list of prefixes to search.
Rerooting essentially means concatenating 2 paths, unless the
considered prefix is a subfolder of the root path.
What happened was that the first considered value was
'/home/qt/work/qt/install/home/qt/work/qt/install', a non-existent
location that gets discarded.
The second considered value was '/home/qt/work/qt/install/target.
The second value is the result of seeing that
'/home/qt/work/qt/install/target' is a subfolder of
'/home/qt/work/qt/install' and thus the root path is stripped.
All of this is done in cmFindPackageCommand::FindConfig() ->
cmFindCommon::RerootPaths.
The behavior above caused the target tools be found instead of the
host ones.
Before the host reuse change, both of the initial constructed prefixes
were discared due to them not existing, e.g.
'/home/qt/work/qt/install/target/home/qt/work/qt/install/target'
and '/home/qt/work/qt/install/host/home/qt/work/qt/install/host'
One of the later prefixes combined CMAKE_FIND_ROOT_PATH ==
'/home/qt/work/qt/install/host' + CMAKE_PREFIX_PATH == '/' resulting
in '/home/qt/work/qt/install/host/' and this accidentally found the
host tools package.
We actually stumbled upon this issue a while ago when implementing Qt
5.14 Android CMake support in 52c799ed44
That commit message mentions the fix is to add a "lib/cmake"
suffix to the PATHS option of find_package().
This would cause the subfolder => strip root behavior mentioned
above.
So finally the fix.
First, make sure not to append QT_HOST_PATH in the toolchain file,
there shouldn't be any need to do that, give that we temporarily set
it when looking for Tools packages.
Second, recreate the subdir scenario in the Qt toolchain file by
setting CMAKE_FIND_ROOT_PATH to the current (relocated) install
prefix as usual, but also setting CMAKE_PREFIX_PATH to a new value
poining to the CMake directory.
Aka '/home/alex/qt' and '/home/alex/qt/lib/cmake'.
Third, when a QT_HOST_PATH is given, save 2 paths in the generated Qt
toolchain: QT_HOST_PATH and QT_HOST_PATH_CMAKE_DIR. There are the host
equivalents of the target ones above. Use these values when looking
for host tools in Qt6CoreModuleDependencies.cmake, again facilitaing
the subdir behavior.
Note these are currently absolute paths and are not relocatable.
We'll have to figure out if it's even possible to make the host path
relocatable.
Finally as a cleanup, look for the Qt6HostInfo package in QtSetup
strictly in the given QT_HOST_PATH, so CMake doesn't accidentally find
a system Qt package.

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.

When cross-compiling, we now create a target_qt.conf file that's to be
used with the host Qt's qmake. With "qmake -qtconf .../target_qt.conf"
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.

Otherwise the Objective-C++ sources will be built with the default
compiler visibility (visible), and then linked with moc-generated
C++ sources that have the Qt overridden hidden visibility, resulting
in linker warnings such as:
ld: warning: direct access in function 'X' from file 'moc_foo.cpp.o'
to global weak symbol 'Y' from file 'bar.mm.o' means the weak symbol
cannot be overridden at runtime. This was likely caused by different
translation units being compiled with different visibility setting

The change fixes the labels to show up correctly in the configure
summary.
It also allows enabling the sanitizer via the feature flags, e.g.
-DFEATURE_sanitize_address=ON.
Finally the qtbase sanitizer option is saved in QtBuildInternalsExtra
so that repos built after qtbase have the same sanitizer options
enabled.

This patch allows tools to be built for the target platform when the
QT_BUILD_TOOLS_WHEN_CROSSCOMPILING parameter is set at configuration
time.
To avoid naming conflicts, the target tools are suffixed with "_native".
The qt_get_tool_target_name() function can be used to get the tool name
for both scenarios (cross and non-cross compilation).
Extend pro2cmake to refer to the right target name for tools.
The relevant write_XXX functions have a new target_ref parameter that
will be "${target_name}" for tools and literally the target name for
everything else.

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.

The install prefix in such a case is the qtbase build dir,
and not the qt6 top-level build dir. This caused issues with
certain incorrect paths being generated, including a broken
qt-cmake-standalone-test script, as well as upon reconfiguration
determining that a non-prefix build should be installed.
The fix for a non-prefix build is to check explicitly for
the qtbase build dir. This works both for super and non-super
builds.

Qt uses the qtNomakeTools() function to mark a directory which will
not be built as part of the default target. This is especially
important when cross-compiling (to iOS for example) because the build
process might fail.
The condition for not building these "GUI tool sub-directory projects"
is the absence of the "tools" value in qmake's QT_BUILD_PARTS
variable.
Introduce a QT_NO_MAKE_TOOLS CMake variable. If the value is true,
it's equivalent to "tools" not being present in QT_BUILD_PARTS.
Introduce qt_exclude_tool_directories_from_default_target().
It's the qmake counter part to qtNomakeTools().
Teach pro2cmake to generate it where appropriate.

Teaches configurejson2cmake about summaries / reports, so things
like enabled features, configure sections, notes, etc.
Add relevant CMake API for adding summary sections and entries,
as well as configure reports. The commands record the passed data,
and the data is later evaluated when the summary needs to be printed.
This is needed, to ensure that all features are evaluated by the
time the summary is printed.
Some report and summary entries are not generated if they mention a
feature that is explicitly exclduded by configurejson2cmake's feature
mapping dictionary. This is to prevent CMake from failing at configure
time when trying to evaluate an unknown feature. We should re-enable
these in the future.
A few custom report types are skipped by configurejson2cmake (like
values of qmake CONFIG or buildParts).
These will have to be addressed a case-by-case basis if still needed.

Depends on a new bleeding edge feature in as-of-yet unreleased
CMake 3.18, that allows building macOS frameworks using the
Ninja Multi-Config generator targeting more than
one configuration.
It uses the new CMAKE_FRAMEWORK_MULTI_CONFIG_POSTFIX_DEBUG
property which tells CMake to create properly named debug artifacts
in the Multi-Config ninja file.
Without it, both debug and release artifacts would have the same
location (no _debug) postfix, so it would be unclear which file
ends up being compiled as last (the debug or release variant).
