I did all the building on my aarch64 board and didn't test the graphical
aspects of running the programs. I also didn't check the
synopsis/description, but some of them do look like they need some work.

patch 1: it turns out the home pages should also be https.

mate-icon-theme and mate-themes don't need gtk in the inputs to build.

libmateweather, mate-panel, mate-control-center: needs a configure flag

mate-applet: it built fine for me with upower as an input

mate-control-center: librsvg and gdk-pixbuf should be propagated

caja: I enabled the display server and the tests still failed on me

mate-metapackage: I copied the build from xfce, it seemed to build fine
for me.

I've attached a diff of what I have. I suggest you alphabetize the
inputs, it makes checking for duplicate or missing inputs much easier.
