Please switch to list + gexps.

Use plain lambda without arguments (lambda _).

Ditto.

Use gexps variables.

Ditto :-).

Same comment bout active tense as earlier... but it seems that'd no
longer be needed with the next comment implemented?

If qmake has a switch like make to change directory, e.g. -C, that'd be
preferable, else "with-directory-excursion" to avoid keeping state in
