<p>Hi,<o:p></o:p></p>
<p>Assuming you're speaking about how to link against internal copy with CMake builds, cf GDAL_USE_TIFF_INTERNAL and
<span class="pre">GDAL_USE_JPEG_INTERNAL</span> at <a href="https://urldefense.com/v3/__https:/gdal.org/development/building_from_source.html*tiff__;Iw!!ACWV5N9M2RV99hQ!J4ZpckslhF-pMKh63wut6u59ulUGlFppObpXHbYwyIrsz-5l72L9XzCYGVOfvJFFFQuMCVW88PwKz_ECg1Ih6_xMPa-T$">
https://gdal.org/development/building_from_source.html#tiff</a> and <a href="https://urldefense.com/v3/__https:/gdal.org/development/building_from_source.html*jpeg__;Iw!!ACWV5N9M2RV99hQ!J4ZpckslhF-pMKh63wut6u59ulUGlFppObpXHbYwyIrsz-5l72L9XzCYGVOfvJFFFQuMCVW88PwKz_ECg1Ih62IxHq7c$">
https://gdal.org/development/building_from_source.html#jpeg</a><o:p></o:p></p>
<p>Even if you set those, you can still get external libtiff or libjpeg dependency, if you also link to a GDAL dependency that links against those, like libgeotiff, librasterlite2, ...<o:p></o:p></p>
