[gdal-dev] Proposal: Native MrSID DSDK Support for Upcoming GDAL Version

[Surendrakumar Dandru]

Dear GDAL Developers,

Native integration of the *DSDK* would allow GDAL to *decode MrSID files
out-of-the-box*, while fully respecting the decode-only licensing
restrictions. This would simplify workflows and improve accessibility for
users who rely on MrSID data.

I am happy to provide guidance or assistance with build integration and
testing on Windows and Linux platforms to ensure a smooth implementation.

Thank you for considering this proposal. I look forward to your feedback.
