Is GTK+ 3.x required for source build?
Seems, strictly speaking, it is not needed for the build:
https://git.alpinelinux.org/cgit/aports/tree/main/at-spi2-atk/APKBUILD
https://packages.debian.org/unstable/source/at-spi2-atk
I have next ones:
Packages with currently host architecture: meson
ninja
pkg-config
.
Packages with target architecture: at-spi2-core
atk
dbus
glib
libxml2
.
Thank you.
