[gdal-dev] Issue with Missing "gdal_MG4Lidar.dll" in GDAL 3.9.3 Build

Hello

I am currently building GDAL 3.9.3 using CMake with the following configuration:

I have specified below flags

<arg value="-DGDAL_BUILD_OPTIONAL_DRIVERS=ON"/>
<arg value="-DGDAL_USE_MRSID=ON"/>
<arg value="-DMRSID_LIBRARY=${unpack.dir.modified}/mrsid/Raster_DSDK/lib/lti_dsdk.lib"/>
<arg value="-DMRSID_INCLUDE_DIR=${unpack.dir.modified}/mrsid/Raster_DSDK/include"/>

The build process produces gdal_MrSID.dll, but I am not seeing the gdal_MG4Lidar.dll. Previously, with GDAL 3.3, both these DLLs were generated successfully.
I suspect the following CMake options might no longer be valid, as they seem to have no effect:

<arg value="-DMRSID_LIDAR_LIBRARY=${unpack.dir.modified}/mrsid/Lidar_DSDK/lib/lti_lidar_dsdk.lib"/>
<arg value="-DMRSID_LIDAR_INCLUDE_DIR=${unpack.dir.modified}/mrsid/Lidar_DSDK/include"/>


Could someone please clarify what might be missing or what changes are needed to generate gdal_MG4Lidar.dll in GDAL 3.9.3?
Thank you for your assistance.

Best regards,
Parveen
