not much we can do I think.. lots of forks..

Make smaller pkgbuild files like qt6.

Make smaller pkgbuild files like qt6.

I tried, but It is not easy to deal with qmake buildsystem.

I've also tried to split qt5 packages but got a dead end with some path issues. The media-autobuild-suite guys did something with qt5 static build /cc @1480c1

For qt5 building, we first built https://github.com/qt/qtbase.git, then https://github.com/qt/qtdeclarative.git, then https://github.com/qt/qtsvg.git, and so on, in rough terms, the order was

export QMAKE_CXX=$CXX QMAKE_CC=$CC
export MSYS2_ARG_CONV_EXCL="--foreign-types="
_check=(bin/qmake.exe Qt5Core.pc Qt5Gui.pc Qt5Widgets.pc)
https://github.com/qt/qtbase.git

_deps=(Qt5Core.pc)
_check=(Qt5Quick.pc Qt5Qml.pc)
https://github.com/qt/qtdeclarative.git

_deps=(Qt5Core.pc)
_check=(Qt5Svg.pc)
https://github.com/qt/qtsvg.git

_deps=(Qt5Core.pc Qt5Quick.pc Qt5Qml.pc)
_check=("$LOCALDESTDIR/qml/QtGraphicalEffects/libqtgraphicaleffectsplugin.a")
https://github.com/qt/qtgraphicaleffects.git

_deps=(Qt5Core.pc Qt5Quick.pc Qt5Qml.pc)
_check=(Qt5QuickControls2.pc)
https://github.com/qt/qtquickcontrols2.git

where the _check refers to a file that was installed in the install stage and the _deps array refers to what files the package depends on. This isn't all of qt's stuff afaik, but just the stuff needed for vlc

Yep. Fork overhead is even worse on ARM64 with emulation overhead added on 😬
