Dear Maintainer,

Your package FTBFS with GDAL 3.13.0:

 error: invalid conversion from 'CSLConstList' {aka 'const char* const*'} to 'char**' [-fpermissive]

>From GDAL 3.13.0 NEWS:

 * GDALMajorObject: Use CSLConstList for GetMetadata, SetMetadata (API breakage)

https://github.com/OSGeo/gdal/blob/v3.13.0beta1/NEWS.md

The attached patch fixes the issue.

Kind Regards,

Bas
