Tue Oct 27 20:58:30 UTC 2015


In case cairo support is (auto-)detected cairo PNG support
is required.

Fixes ([1]):

../gst-libs/gst/video/.libs/libgstvalidatevideo-1.0.so: undefined reference to `cairo_surface_write_to_png'
../gst-libs/gst/video/.libs/libgstvalidatevideo-1.0.so: undefined reference to `cairo_image_surface_create_from_png'
collect2: error: ld returned 1 exit status
