Write find_dependency() calls in Qt Module config files
This change introduces a new function called qt_find_package()
which can take an extra option called PROVIDED_TARGETS, which
associates targets with the package that defines those targets.
This is done by setting the INTERFACE_QT_PACKAGE_NAME and
INTERFACE_QT_PACKAGE_VERSION properties on the imported targets.
This information allows us to generate appropriate find_dependency()
calls in a module's Config file for third party libraries.
For example when an application links against QtCore, it should also
link against zlib and atomic libraries. In order to do that, the
library locations first have to be found by CMake. This is achieved by
embedding find_dependency(ZLIB) and find_dependency(Atomic) in
Qt5CoreDependencies.cmake which is included by Qt5CoreConfig.cmake.
The latter is picked up when an application project contains
find_package(Qt5Core), and thus all linking dependencies are resolved.
The information 'which package provides which targets' is contained
in the python json2cmake conversion script. The generated output of
the script contains qt_find_package() calls that represent that
information.
The Qt5CoreDependencies.cmake file and which which dependencies it
contains is generated at the QtPostProcess stop.
Note that for non-static Qt builds, we only need to propagate public
3rd party libraries. For static builds, we need all third party
libraries.
In order for the INTERFACE_QT_PACKAGE_NAME property to be read in any
scope, the targets on which the property is set, have to be GLOBAL.
Also for applications and other modules to find all required third
party libraries, we have to install all our custom Find modules, and
make sure they define INTERFACE IMPORTED libraries, and not just
IMPORTED libraries.

Write find_dependency() calls in Qt Module config files
This change introduces a new function called qt_find_package()
which can take an extra option called PROVIDED_TARGETS, which
associates targets with the package that defines those targets.
This is done by setting the INTERFACE_QT_PACKAGE_NAME and
INTERFACE_QT_PACKAGE_VERSION properties on the imported targets.
This information allows us to generate appropriate find_dependency()
calls in a module's Config file for third party libraries.
For example when an application links against QtCore, it should also
link against zlib and atomic libraries. In order to do that, the
library locations first have to be found by CMake. This is achieved by
embedding find_dependency(ZLIB) and find_dependency(Atomic) in
Qt5CoreDependencies.cmake which is included by Qt5CoreConfig.cmake.
The latter is picked up when an application project contains
find_package(Qt5Core), and thus all linking dependencies are resolved.
The information 'which package provides which targets' is contained
in the python json2cmake conversion script. The generated output of
the script contains qt_find_package() calls that represent that
information.
The Qt5CoreDependencies.cmake file and which which dependencies it
contains is generated at the QtPostProcess stop.
Note that for non-static Qt builds, we only need to propagate public
3rd party libraries. For static builds, we need all third party
libraries.
In order for the INTERFACE_QT_PACKAGE_NAME property to be read in any

Also for applications and other modules to find all required third

Implement developer / non-prefix builds
A non-prefix build is a build where you don't have to run
make install.
To do a non-prefix build, pass -DFEATURE_developer_build=ON when
invoking CMake on qtbase. Note that this of course also enables
developer build features (private tests, etc).
When doing a non-prefix build, the CMAKE_INSTALL_PREFIX cache variable
will point to the qtbase build directory.
Tests can be run without installing Qt (QPA plugins are picked up from
the build dir).
This patch stops installation of any files by forcing the
make "install" target be a no-op.
When invoking cmake on the qtsvg module (or any other module),
the CMAKE_INSTALL_PREFIX variable should be set to the qtbase build
directory.
The developer-build feature is propagated via the QtCore Config file,
so that when building other modules, you don't have to specify it
on the command line again.
As a result of the change, all libraries, plugins, tools, include dirs,
CMake Config files, CMake Targets files, Macro files, etc,
will be placed in the qtbase build directory, mimicking the file layout
of an installed Qt file layout.
Only examples and tests are kept in the separate module build
directories, which is equivalent to how qmake does it.
The following global variables contain paths for the
appropriate prefix or non prefix builds:
QT_BUILD_DIR, QT_INSTALL_DIR, QT_CONFIG_BUILD_DIR,
QT_CONFIG_INSTALL_DIR. These should be used by developers
when deciding where files should be placed.
All usages of install() are replaced by qt_install(), which has some
additional logic on how to handle associationg of CMake targets to
export names.
When installing files, some consideration should be taken if
qt_copy_or_install() needs to be used instead of qt_install(),
which takes care of copying files from the source dir to the build dir
when doing non-prefix builds.
Tested with qtbase and qtsvg, developer builds, non-developer builds
and static developer builds on Windows, Linux and macOS.

Ugly fix for handling QT_SOURCE_TREE
QT_SOURCE_TREE is a variable that is set in qtbase/.qmake.conf.
In qtbase, it's used throughout various
projects to find cpp sources when building standalone tests (among
other things).
Everything works fine with qmake, because even if qmake is invoked
on the tests subfolder, qmake searches up the source directory tree
until it finds a .qmake.conf file, and uses that.
When building qttools with qmake, the qdoc project expects
to have a QT_SOURCE_TREE value, but it's not actually set in the
qttools/.qmake.conf file, so the generated include paths that use
that value are incorrect. Curiously the build still succeeds.
Now in CMake land we replaced QT_SOURCE_TREE with
CMAKE_SOURCE_DIR, but that does not work properly when doing a
standalone tests build, because the project in that case is the
tests one, and not the qtbase one, so configuration fails in a
developer build when trying to configure some private tests.
So far I've found that only qtbase actively uses this value.
A temporary fix is to save the qtbase source directory into a
QT_SOURCE_TREE variable inside the generated
BuildInternalsExtra.cmake file.
The pro2cmake script is changed to handle presence of QT_SOURCE_TREE
in a qrc file path. This is handled by finding the location of a
.qmake.conf file starting from the project file absolute path.
This is needed to stop the script from crashing when handling
the mimedatabase test projects for example.
The change also regenerates the relevant failing test projects, and
thus standalone tests (when doing developer builds aka private_tests
enabled) now configure and build successfully.

CMake: Handle automatic rpath embedding correctly
Instead of using CMAKE_INSTALL_RPATH to embed an absolute path
to prefix/libdir into all targets, use the more sophisticated aproach
that qmake does.
For certain targets (modules, plugins, tools) use relative rpaths.
Otherwise embed absolute paths (examples, regular binaries).
Installed tests currently have no rpaths.
On certain platforms rpaths are not used (Windows, Android,
iOS / uikit).
Frameworks, app bundles and shallow bundles should also be handled
correctly.
Additional rpaths can be provided via QT_EXTRA_RPATHS variable
(similar to the -R option that configure takes).
Automatic embedding can be disabled either via QT_FEATURE_rpath=OFF
or QT_DISABLE_RPATH=ON.
Note that installed examples are not relocatable at the moment (due
to always having an absolute path rpath), so this is a missing feature
compared to qmake. This is due to missing information on where
examples will be installed, so a relative rpath can not be computed.
By default a Qt installation is relocatable, so there is no need to
pass -DQT_EXTRA_RPATHS=. like Coin used to do with qmake e.g. -R .
Relative rpaths will have the appropriate 'relative base' prefixed
to them (e.g $ORIGIN on linux and @loader_path on darwin platforms).
There is currently no support for other platforms that might have a
different 'relative base' than the ones mentioned above.
Any extra rpaths are saved to BuildInternalsExtra which are re-used
when building other repositories.
configurejson2cmake modified to include correct conditions for the
rpath feature.
It's very likely that we will need a new qt_add_internal_app()
function for gui apps that are to be installed to prefix/bin.
For example for Assistant from qttools. Currently such apps
use qt_add_executable().
The distinction is necessary to make sure that relative rpaths are
embedded into apps, but not executables (which tests are part of).

CMake: Allow building bundled 3rd party libraries in qtbase
A few things are needed to accomplish that:
- the python scripts do not ignore certain system_foo features anymore
(it is a hardcoded list for now just to be safe)
- configurejson2cmake now outputs
qt_find_package(WrapSystemFoo) calls for bundled libraries
(see below)
- the harfbuzz .pro file is modified to accommodate pro2cmake
not being able to correctly parse some conditional scopes
- the freetype .pro file is modified to make sure linking of the
library succeeds without duplicate symbol errors, which qmake
doesn't encounter due to magical exclusion of cpp files that are
included in other cpp files (presumably for include moc_foo.cpp
support)
- feature evaluation for Core, Gui, Network now happens in the
qtbase/src directory, so that bundled libraries can be conditionally
built
- for each bundled library there are now two FindWrap scripts:
- FindWrapSystemFoo which finds an installed library in the system
- FindWrapFoo which either uses the system installed library or
the built bundled one depending on a condition
- projects that intend to use bundled libraries need to link against
WrapFoo::WrapFoo instead of WrapSystemFoo::WrapSystemFoo targets
(this is handled by pro2cmake).
Unfortunately manually added qt_find_package(WrapFoo) calls might
still be needed as is the case for WrapFreetype and others.
- a new cmake/QtFindWrapHelper.cmake file is added that provides
a macro to simplify creation of WrapFoo targets that link against
a bundled or system library. The implementation is fairly ugly
due to CMake macro constraints, but it was deemed better than
copy-pasting a bunch of almost identical code across all
FindWrapFoo.cmake files.
- a qtzlib header-only module is now created when using bundled
zlib, to provide public syncqt created headers for consumers
that need them. These are projects that have
'QT_PRIVATE += zlib-private' in their .pro files
(e.g. qtimageformats, qtlocation, qt3d, etc.)
This is unfortunately needed due to QtNetwork using zlib
types in its private C++ API.
The change includes support for building the following bundled
libraries:
- zlib
- libpng
- libjpeg
- Freetype
- Harfbuzz-ng
- PCRE2
The following 3rd party libraries are still using an old
implementation within the CMake build system, and should be migrated
to the new one in the near future:
- double-conversion
- Old harfbuzz
The are a few libraries that are not yet ported:
- system-sqlite
- systemxcb
- maybe others
Among other things, this change allows building qtbase on Windows
without requiring vcpkg.
