Hi,

you need to download the ECW SDK from https://supportsi.hexagon.com/s/article/ERDAS-ECW-JP2-SDK-v5-5-Update-4-Release-Announcement?language=en_US and install it

and then point to it with the CMake variables indicated at https://gdal.org/development/building_from_source.html#ecw

Cf https://github.com/jef-n/OSGeo4W/blob/6a17ff489bd6dcd583cbfa51b542966ba2961c7d/src/gdal/osgeo4w/package.sh#L150 for the build recipee of the OSGeo4W GDAL build with ECW support

Hi,

I've build GDAL version 3.8.3 in VS2019 from source files "gdal-3.8.3.tar.gz". For creating project file "GDAL.vcxproj"

I used CMake program. I've added variables PROJ_INCLUDE_DIR = C:\OSGeo4W\include and PROJ_LIBRARY = C:\OSGeo4W\lib\proj.lib

and everything worked fine. When I added gdal.dll to our project ... it worked fine, it convert raster files and so on. But I have one problem,

I need to add ECW plugin to GDAL 3.8.3 project. Could you help me, how to do it ... ?

Thanks in advance, Marian Hadri
