[Paraview] /usr/bin/paraview not packaged with CPack in Paraview 4.3.1 Superbuild

Another quick follow up (sorry!) 

[pid   360] stat("/home/acrognale/paraview/build/qt/src/qt/src/3rdparty/libpng", {st_mode=S_IFDIR|0755, st_size=4096, ...}) = 0

It seems to not be finding libpng.so even though it exists as a symbolic link to libpng14d.so.14.8.0, which does indeed exist.

Thoughts?

Trying yet another build from a completely clean working slate now.

Yeah, it looks like it built against the superbuild's libpng and running
against the one you grabbed. Other than a compiler and things like libc
or OpenGL, the superbuild *should* be providing everything it needs (and
it is not regularly tested against other external dependency versions).

Using the superbuild-provided png would probably be best
(-DUSE_SYSTEM_png=OFF -DENABLE_png=ON). However, it seems that removing
the 1.6.18 libpng should fix the warning.
