I notice that the LINK_EXTERNAL macro won't distinguish between debug
and release dependences, which means that osgDB will use the release
version of zlib for all build configurations. Under Win32, this will
cause a manifest problem: all applications using osgDB may complain
"failed to start because msvcr80.dll was not found" or similar
messages.
This change will make it back to normal."
