[Mesa-dev] [PATCH kmscube] texturator: Only define png variable when libpng is present

[Fabio Estevam]

When libpng is not present the following build warning is seen:

../texturator.c:98:13: warning: 'png' defined but not used [-Wunused-variable]
 static bool png;

Fix it by only defining the png variable when HAVE_LIBPNG is defined.
