Before we only exported features that had outputType PUBLIC or PRIVATE
on the various "QT_ENABLED_PUBLIC_FEATURES" target properties.
Now we also export features that have output type privateConfig,
publicConfig and publicQtConfig.
The new properties names are:
- QT_QMAKE_PUBLIC_CONFIG for outputType == publicConfig
- QT_QMAKE_PRIVATE_CONFIG for outputType == privateConfig
- QT_QMAKE_PUBLIC_QT_CONFIG for outputType == publicQtConfig
These need to be exported for 2 reasons:
- other modules that need to check the config values
- in preparation for generating proper qmake .prl and .pri
information for each module
Note that the config values are now considered actual features
when doing condition evaluation. So if there exists a feature "ssse3"
with outputType privateConfig, its enabled state can be checked via
QT_FEATURE_ssse3 in consuming modules (but not in the declaring
module).
These config values are also placed in the respective
QT_ENABLED_PUBLIC_FEATURES, QT_ENABLED_PRIVATE_FEATURES properties
when exporting a target, so the properties will now contain both
features and config values.
In order to make this work, feature name normalization has to happen
at CMake time, rather than done by the python script.
This means that features like "developer-build" need to retain the
dash in the qt_feature(), qt_feature_definition() and
qt_feature_config() calls, rather than generating "developer_build"
as the script did before.
The normalization is done at CMake time. Feature conditions,
CMake code, and -DFEATURE_foo=bar options passed on the command line
should still use the underscore version, but the original name is used
for the QT_QMAKE_PUBLIC_CONFIG properties.
Note that "c++11" like features are normalized to "cxx11".
Implementation wise, the configurejson2cmake script is adjusted to
parse these new output types.
Also QtBuild and QtFeature are adjusted to save the config values
in properties, and re-export them from GlobalConfig to Core.

When a feature generates a private feature, we should not just repeat
the condition but also make it depend on the original feature. In qmake
features had different outputs, while we have a 1:1 mapping. For example
the developer_build feature had "private_tests" as an output feature.
There's no condition attached to the feature and auto-detect is off, so
we'd generate
qt_feature("developer_build" AUTODETECT OFF)
qt_feature("private_tests" AUTODETECT OFF)
and that's wrong, because when the user enables the visible feature
(developer_build) we want it to propagate to the private_tests feature.

It doesn't make much sense to look for X11 related packages on
macOS and Windows by default. Usually they would not be there, and
as a result the configuration step would show a long list of scary
not found packages, and also eat precious configure time.
Change the conversion script to allow putting conditions around
generated find_package calls.
These conditions can be manually set in the conversion script
library mapping, using the emit_if argument,
which we do for the X11 and Wayland related packages.
They are also computed by checking which features use a given library,
and if the feature is protected by a simple emitIf condition like
config.linux, the relevant library find_package call will be protected
by the same condition.
If a developer still wishes to look for all packages, they can define
the CACHE variable QT_FIND_ALL_PACKAGES_ALWAYS to ON.
The relevant configure.cmake files are regenerated in this patch.

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.

The former can now be checked in CMake with via TEST_subarch_foo and

The latter can now be checked by
