[Paraview] [Non-DoD Source] PVSB on Mac OSX 10.12

[Angelini, Richard C (Rick) CIV USARMY RDECOM ARL (US)]

Chuck – I ran a clean build on my OS X 10.12 system and added the flag
“-DUSE_SYSTEM_png=OFF” to my top-level cmake command – and I still get the
same failure deep down inside of the ParaView build – can’t find <png.h>……
Cmake must be seeing something in the OS X 10.12 environment that’s
different from everywhere else that’s causing a misconfiguration ….

Hi Rick,

When using the superbuild, ParaView should always be using a "system" PNG.
The diggerence is whether that will be provided by the OS or the superbuild.
Either way, it's external to the paraview subproject.  Try explicitly
setting -DUSE_SYSTEM_png=OFF when configuring the superbuild.  I'll look
into why the superbuild doesn't properly handle this in the first palce but
explicitl;y setting the option should make your build work.
