Even after reading your other mails, I'm not 100% sure I understand
what you want to do.

Say you have

    icontheme1/actions/16/some_action.svg
    icontheme1/...
    icontheme1/index.theme

    icontheme2/actions/16/some_action.svg
    icontheme2/...
    icontheme2/index.theme

    icontheme3/actions/16/some_action.svg
    icontheme3/...
    icontheme3/index.theme

    icontheme4/actions/16/some_action.svg
    icontheme4/...
    icontheme4/index.theme

perhaps with inheritances icontheme4 -> icontheme3 -> icontheme2 -> icontheme1.

Then shouldn't you be able to just generate something like:

iconthemes.rcc:

<RCC>
  <qresource prefix="/icons">
    <file>icontheme1/actions/16/some_action.svg</file>
    <file>icontheme1/...</file>
    <file>icontheme1/index.theme</file>

    <file>icontheme2/actions/16/some_action.svg</file>
    <file>icontheme2/...</file>
    <file>icontheme2/index.theme</file>

    <file>icontheme3/actions/16/some_action.svg</file>
    <file>icontheme3/...</file>
    <file>icontheme3/index.theme</file>

    <file>icontheme4/actions/16/some_action.svg</file>
    <file>icontheme4/...</file>
    <file>icontheme4/index.theme</file>
  </qresource>
</RCC>

I.e. putting the iconthemes side by side in :/icons in the RCC namespace.

If the application then QIcon::setThemeName("icontheme4"), I think it
should just work? Why do you need to merge the index.theme files?

I'm most probably missing some aspect here, but if you now correct me,
it will hopefully help us understand :)
