request: add jpegxl as a dependency

[AndrewAnnex]

Comment:

In contrast to #722, I'd like to request the addition of a new dependency of JPEG-XL (https://github.com/libjxl/libjxl).

This would enable the jpegxl driver for GDAL and many neat compression options that brings to COGs.

cf conda-forge/imagecodecs-feedstock#48 : the main issue would be to add libjxl itself in conda-forge

I did see https://github.com/conda-forge/libjxl-split-feedstock, which seems to be building libjxl but haven't looked into it too much to see why the name isn't exactly libjxl.

seems promising.

Note that GDAL would have to be built with -DGDAL_USE_TIFF_INTERNAL=YES and -DGDAL_USE_GEOTIFF_INTERNAL=ON to have the libjxl codec builtin (cf https://lists.osgeo.org/pipermail/gdal-dev/2023-March/056983.html)

but haven't looked into it too much to see why the name isn't exactly libjxl.

perhaps because it issues separate libjxl and libjxl-tools packages?

Indeed, it is a multi-output package that creates those two packages, see
