audacity: segmentation fault during startup

After downgrade it doesn't happen for me anymore, but we'll need to fix it somehow anyway, so I'm leaving this open.

@FRidh @vcunat It sounds like a problem upgrading from wxGTK30 -> wxGTK31. I build audacity with the gtk3 variant and it launches fine for me:

(audacity.override {
    # Build with GTK3 for HiDPI scaling
    wxGTK31 = wxGTK31-gtk3;
})

Maybe let's wait with looking into this until #94905 has been merged (which is waiting for an upstream fix to be released)

[raboof]

The fix for the cmake problem is now on master.

Cherry-picking the previous update attempt, in https://github.com/raboof/nixpkgs/pull/new/audacity-2.4.1-to-2.4.2-take2, indeed now reproduces a segfault for me.

The problem had been reverted. More information and followup in PR #97370.
