[Qgis-user] building gdal for mrsid

[Even Rouault]

No, this won't be a .deb, and using the past .deb for mrsid won't work 
since the switch to CMake

General instructions to build GDAL from source are at 
https://gdal.org/development/building_from_source.html

To install it in a location where it won't mess with with your packaged 
GDAL, do for example

cmake .. -DCMAKE_INSTALL_PREFIX=/opt/gdal-3.8.3 (others options here 
such as -DMRSID_ROOT=... -DECW_ROOT=... )

(or any other installation directory of your choice)
