In fact I would add problem number 0: it picks up system libs in /usr/lib64 over /usr/lib,
while lib64 is just some compatibility symlink. I'd rather see it find
PNG_LIBRARY:FILEPATH=/usr/lib/libpng.so
than
PNG_LIBRARY:FILEPATH=/usr/lib64/libpng.so
for instance. Maybe a realpath() call would be a good idea?

Yes.
