Hello Even,
Thanks for clarifying.
One more question - Our end-users is trying to use the GDAL shared libs (built
with internal GeoTIFF and external libTIFF) in a setup where even they have
external GeoTIFF and libTIFF libraries.
Can I do something to avoid the symbol clashes in Client setup while building
the GDAL ?

John,
yes I believe this should work (although probably not much tested).
The reverse is explicitly forbidden though (from frmts/gtiff/CMakeLists.txt):
if (GDAL_USE_TIFF_INTERNAL AND NOT GDAL_USE_GEOTIFF_INTERNAL)
message(FATAL_ERROR "When GDAL_USE_TIFF_INTERNAL=ON,
GDAL_USE_GEOTIFF_INTERNAL must be also set to ON")
endif ()

Hi
Is this allowed if I use GDAL Internal Geotiff and external libtiff library
while building GDAL? What all things I need to take care.
Will there be any symbol clashes etc which I need to handle as well?
<arg value="-DGDAL_USE_GEOTIFF_INTERNAL=ON"/>
<arg value="-DGDAL_USE_TIFF_INTERNAL=OFF"/> //Specify external libtiff include
and libs My end goal is to have below Options enabled when I run gdalinfo.exe
--format gtiff
