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

Follow up,

Performing build step for 'qt'

After removing libpng 1.2 (Debian version), libpng 1.6.18 (version I compiled from source), and making sure USE_SYSTEM_png=OFF and ENABLE_png=ON were both set.

Thoughts?

Thanks,
Anthony

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.
