new package: qt6-qt5compat

[knyipab]

Grateful for considering to merge this.

I am trying to build krita with all deps ready, but this qt6-qt5compat cannot be built together in one PR, cuz other krita deps (of deps) requires qt5-qtbase which messes up the build process of qt6-qt5compat. Merging this PR is needed in order to proceed to building krita (though using krita git qt6 version. Cuz termux's qt5 doesn't support opengl and won't build).

Deps and build deps take ref to https://archlinux.org/packages/extra/x86_64/qt6-5compat/ and also verified to be sufficient by looking at its cmakelists.txt

LGTM.

Do you have any particular package in mind that required qt5compat?

[knyipab]

Krita (git ver, for now, enough to prove qt6-qt5compat working). I have all deps ready in this branch, just qt6-qt5compat building messed up by other deps, shown at this GitHub action.

A lot of kf6 packages seem to need qt6-qt5compat.

Please move qt6-qtdeclarative to DEPENDS.
I can see
lib/qt6/qml/Qt5Compat/GraphicalEffects/libqtgraphicaleffectsplugin.so and lib/qt6/qml/Qt5Compat/GraphicalEffects/private/libqtgraphicaleffectsprivateplugin.so
needs libQt6Qml.so.6.

I did that only becuz archlinux state it as optional "qt6-declarative (optional) - for QtGraphicalEffects" and they also have the mentioned .so files in the package.

I have no strong view and termux may have different philosophy. May I just confirm once that it is more preferred to move qt6-qtdeclarative to DEPENDS?

Thank you : )

Ok, I assume that you still want to put it in the DEPENDS, so I edited. Let me know for any issues before merging.
