  # muse-sounds-manager installs Muse Sounds sampler libMuseSamplerCoreLib.so.

  # It requires that argv0 of the calling process ends with "/mscore" or "/MuseScore-4".

  # We need to ensure this in two cases:

  #

  # 1) when the user invokes MuseScore as "mscore" on the command line or from

  #    the .desktop file, and the normal argv0 is "mscore" (no "/");

  # 2) when MuseScore invokes itself via File -> New, and the normal argv0 is

  #    the target of /proc/self/exe, which in Nixpkgs was "{...}/.mscore-wrapped"

  #

  # In order to achieve (2) we install the final binary as $out/libexec/mscore, and

  # in order to achieve (1) we use makeWrapper without --inherit-argv0.

  #

  # wrapQtAppsHook uses wrapQtApp -> wrapProgram -> makeBinaryWrapper --inherit-argv0

  # so we disable it and explicitly use makeQtWrapper.

  #

  # TODO: check if something like this is also needed for macOS.
