[gdal-dev] Where to fins my own files

Hi,

actually the below question made me reconsider the current monolithic 
approach how data files are store in the source tree, to a cleaner one 
where each driver stores its potential data files in a specifc 
subdirectory and is responsible to install them (still in 
$prefix/share/gdal) : https://github.com/OSGeo/gdal/pull/9087 . This 
improves relating data files to the driver that need them.

This has no impact on the installed artifacts. Note that when working 
with a development build, GDAL_DATA should now point to 
${top_build_dir}/data, and no longer to ${top_source_dir}/data.
