Comment:
Lo and behold:

```
index: added `pantheon-session-20200331_1' (x86_64).
index: 11 packages registered.
=> pantheon-session-20200331_1: removing autodeps, please wait...
=> pantheon-session-20200331_1: cleaning build directory...
=> pantheon-session: removing files from destdir...
```

Edit: It seems to work when I try to build `wingpanel` directly and then `pantheon-session`. IIRC there was an issue open that deps of dependencies are not built automatically? 

Edit2: Looks like an older `ccache` was at fault. Thanks everybody for the quick help!
