But I knew where to look. So I thought I'd better share my way of learning rather than just the solution ;) I started with grep -R 'export' ~/.config/guix/current/share/guile/site/3.0/gnu/packages/ | less That showed a lot of results. I noticed a line like this > /home/urz/.config/guix/current/share/guile/site/3.0/gnu/packages/engineering.scm: (setenv "HOME" (getcwd)) ;; cmake needs this to export modules Thought it might be the thing I was looking for, so I did less /home/urz/.config/guix/current/share/guile/site/3.0/gnu/packages/engineering.scm and navigated to this line. This seems to be it. The (setenv) function. Can be used as from a modified packaging phase function (as you can see in engineering.scm). Hope I helped. Good luck once again! W. P.S. Make sure you know some 'less' shortcuts if you're going to do things this way.
