Windows installation package size

Tue Apr 15 20:02:58 BST 2025

Hi Maik,

A binary under windows cannot be stripped like under Linux. debug
symbols are hosted in a separate file .pdb.

So, the NVIDIA dll is huge as well...

There is also the redistributable status of the NVIDIA sdk. The
response is no, as I can see. So typically we cannot host files in the
digiKam bundle.

This means that dll must be removed from the installer and the end
user must install the both packages from NVIDIA on the target computer
to have the benefit to support OpenCL in digiKAm.
