commit 7c14ff94e31990eb0932f55942edb75f30f6b24d
Author: Enrico Forestieri <for...@lyx.org>

Fix bug #10718
Due to the peculiarities of Windows, it may happen that
pdftocairo is built without png support when compiled on this
platform. Unless explicitly requested (maybe for some peculiar
application and certainly not for usual distros), this is
highly improbable to occur on other platforms.
