Sorry, I don't get the question, these are devel packages, not runtime
libraries, these dependencies of dependencies are already pulled if I
install gtk3, but code that only links with GTK3, only needs gtk3-devel
to be built, the others devel packages are only needed if my code links
to them directly.
You intentionally (or not) didn't reply to my comment on this. Just look
into gtk+-3.0.pc:
Sorry not intentional, was dumbfounded on why on my machine dnf removing
openssl-devel was removing krb5-devel when you showed no dependency was
present (don't know why yet), that skipped the rest of the email.
Requires: gdk-3.0 atk >= 2.15.1 cairo >= 1.14.0 cairo-gobject >= 1.14.0
gdk-pixbuf-2.0 >= 2.30.0 gio-2.0 >= 2.49.4
Requires.private: atk atk-bridge-2.0 wayland-client >= 1.9.91
wayland-protocols >= 1.12 xkbcommon >= 0.2.0 wayland-cursor >= 1.9.91
wayland-egl epoxy >= 1.0 pangoft2 gio-unix-2.0 >= 2.49.4
All those wayland and xkb stuff is needed only if you link to gtk
statically. But since we don't ship static library, no one can use it
anyway → those requirements are useless.
If it doesn't break stuff for other people, and it shouldn't, this is a
great find, thanks.
The problem here is that they are auto-generated and I've proposed to
improve that.
