The nixpkgs-unstable channel's programs.sqlite was used to identify
packages producing exactly one binary, and these automatically added
to their package definitions wherever possible.
wrapQtAppsHook ignores Mach-O binaries [1]. Additionally, wrapQtAppsHook
doesn't look inside $out/Applications [2], which is where chatterino2 is
installed. This means chatterino2 for Darwin/macOS is not wrapped
properly, causing the following error when launched:
> qt.qpa.plugin: Could not find the Qt platform plugin "cocoa" in ""
>
> This application failed to start because no Qt platform plugin could
> be initialized. Reinstalling the application may fix this problem.
On macOS, explicitly wrap chatterino2's executable.

On Darwin/macOS, chatterino2's install phase copies no files into the
output. `make install` does not copy chatterino2.app. Copy the .app
manually, fixing the installation.
With this patch, chatterino2 almost works on macOS. Issue #42893
applies, so to make chatterino2 work, you must install qtbase in your
environment. For example:
$ nix-env -iA nixpkgs.qt5.qtbase
$ open ~/.nix-profile/Applications/chatterino.app
