Hi,

As discussed at https://lists.gnu.org/archive/html/guix-devel/2024-12/msg00124.html

The eventual goal is to use Gexp's for everything, everywhere! So closing, please re-open if you think it's a mistake.

Futurile / Steve

It is impossible to refer to %outputs in arguments like #:configure-flags
(ie. `(assoc-ref %outputs "out")` leads to unbound-variable %outputs).
I think the issue is in qt using different system than build systems such
as cmake or gnu. Since I am unsure about the reason for qt not having
the same structure, I am submitting this to guix devel for discussion,
as well as opening a patch in case this is fine to be merged. If not,
could someone please explain what the reason behind not adding
inputs and outputs is, and what is the alternative?

Regards,
Rutherther
