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.

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.
