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).

Consider a negated feature config value like the following:
qt_feature_config("foo" QMAKE_PUBLIC_QT_CONFIG NEGATE)
If this feature was disabled, it would turn up in both,
enabled_features and disabled_features of module .pri files.
Also, QT_CONFIG would contain foo.
Expected however is that QT_CONFIG contains no-foo, and only
disabled_features contains foo.
Fix this by prepending a "no_" prefix to the value, similar to the
"no-" prefix in the qmake build. The qt_correct_config function was
adjusted to recognize "no_foo" and translate it to the qmakeish
"no-foo" config value.
Config values that start with "no_" but do not correspond to a feature
are left untouched. You can still have values like
"no_valley_too_deep" or "no_mountain_too_high".

If a find_package() in a try_compile project doesn't find a package,
and we then link against a non-existent target, the configuration
failure of the compile test also fails the configuration of the

To avoid that, separate library targets from non-targets, and make sure
to only link against the targets if they exist.
pro2cmake now outputs modified compile test project code which iterates

Some library entries in configure.json have a test entry.
An example is assimp in qtquick3d.
qmake tries to find the library via the sources section, and then tries
to compile the test found in config.tests/assimp/assimp.pro while
automagically passing it the include and link flags it found for assimp.
We didn't handle that in CMake, and now we kind of do.
configurejson2cmake will now create a corresponding
qt_config_compile_test call where it will pass a list of packages and
libraries to find and link against.
pro2cmake will in turn generate new code for the standalone
config.test project. This code will iterate over packages that need to
be found (like WrapAssimp) and then link against a list of passed-in
targets.
In this way the config.test/assimp/main.cpp file can successfully
use assimp code (due to propagated include headers).
qt_config_compile_test is augmented to take a new PACKAGES argument,
with an example as follows
PACKAGES PACKAGE Foo 6 COMPONENTS Bar
PACKAGE Baz REQUIRED
The arguments will be parsed and passed to the try_compile project,
to call find_package() on them.
We also need to pass the C/C++ standard values to the try_compile
project, as well as other try_compile specific flags, like the
toolchain, as given by qt_get_platform_try_compile_vars().

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

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.

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.

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.
