indeed it seems the option has never been implemented. I cannot think of a<br>
particular reason why linking against external zlib wouldn't work. This would<br>
require mostly editing the relevant makefiles (the one you mention and other<br>
ones such as in frmts/gtiff/libtiff etc...).<br></blockquote><div><br></div><div>Ok.
