What is the output of the following shell commands?

pkg-config --cflags libotf
pkg-config --libs libotf

If they output "-lpng12", then that's most likely the problem since 'configure' 
uses the output of these commands. You can run './configure --without-libotf' as 
Stefan suggested, or you can investigate why the pkg-config libotf configuration 
is messed up for you. I don't observe the problem on Ubuntu 18.04.3 LTS, for 
what it's worth.
