CPackIFW - Large file packaging : Out of memory

I use CPackIFW package generator to generate my installer.

I am trying to package a large library (400MB) but it is failing because of the size of the file + use of 7zip archiver.

When I replace that file with a small one (0MB), the packaging succeeded. When I use ZIP archiver, it works as well. If I try to package that large file on Mac, it works.

I am aware of this ticket https://bugreports.qt.io/browse/QTIFW-1157 ,

I tried to install the latest 7zip version but is hasn't done any effect.

I also couldn't find any information about how to configure the choice of the archiver (avoid 7z in my case).
