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

[Anthony Crognale]

Ben,

I had been using the system libpng version 1.2.52, but it appears `png_set_longjmp_fn` was not introduced until 1.6, so I tried building libpng 1.6.18 from source last night, which then allows Paraview to continue building with qt enabled, however, when running the built version, I get:

libpng warning: Application built with libpng-1.4.8 but running with 1.6.18

So it appears that there is some other version of libpng (maybe bundled in the superbuild?) that it was using to build.

Should I turn off use_system_png? Turn off ENABLE_png? Something else?

Thanks,
Anthony

"make clean" isn't really reliable in a superbuild. I usually do "rm -rf

Are you using a system libpng? What version is it?

[1]More surgical is "rm -rf install/ */src/*-stamp/*-install", but this
still has cases where it is insufficient.
