This commit proposes a very minimal package for qt6base. It only supports building QtCore, so it *really* is minimal. But that's a starting point, which we can progressively build on top. It is based on initial work from Peter Seiderer. This minimal QtCore build is however sufficient to build and run simple non-graphical Qt applications. A number of comments: - Even though there's only qt6base for now, many other qt6 modules will come later on, which is why we're using the same structure as for qt5, with a subdir for package/qt6/ - Qt6 is mutually exclusive with Qt5. Even though the library names on the target and the location of the header files are distinct, the host tools (qmake, moc and al.) have the same name, so at least for now, we make them mutually exclusive. - We've chosen to use non-bundled libraries for zlib, bb2, double-conversion and pcre2, for both the target and the host qt6base packages. - Contrary to qt5 where the target package was building the host tools, now we have a host qt6base package building the host tools, and which is needed as a dependency for the target qt6base package. - qt6base is using CMake. However, it strongly recommends to use Ninja as a backend instead of make, a recommendation that we follow in this commit. Since we don't have support for Ninja in the cmake-package infrastructure (yet), we do this manually in qt6base.mk itself, by passing -Gninja to CMake at configure time, and then by using cmake --build at build time and cmake --install at install time, using explicitly provided build and install commands. Hopefully these can go away once we have support for Ninja directly in cmake-package. - We disable a number of features or external libraries using FEATURE options. However, because there are over 400 FEATURE options in qt6base, we didn't go all the way to explicitly disabling *all* of them (which would be needed for both the host and target packages). We expect that this list of explicit FEATURE options disabling will need to grow based on the feedback of users and issues encountered.
