[gdal-dev] Internal libtiff version

[Even Rouault]

Hi Luís,

it depends on your GDAL was built.

You can check it  with "gdalinfo --format gtiff | grep LIBTIFF" and it 
will return either LIBTIFF=INTERNAL or LIBTIFF=LIBTIFF, Version X.Y.Z

If it is with its internal libtiff copy, then it corresponds roughly to 
the state of libtiff master at then time the GDAL release was done. 
Looking at 
https://github.com/OSGeo/gdal/blob/v3.6.4/frmts/gtiff/libtiff/tiffvers.h, 
I see we were already past 4.4.0, so it is likely you have a GDAL build 
against an external libtiff that wasn't as current as the GDAL build
