Error linking to libvtkpng-pv5.5.so.1 on ppc64le (RHEL 7)

Builds with the following error.

/home/XXXX/ParaView/build/lib/libvtkpng-pv5.5.so.1: undefined reference to `png_init_filter_functions_vsx'

May be related to RHEL 7 version of png:

$ locate libpng.so /usr/lib64/libpng.so.3 /usr/lib64/libpng.so.3.50.0

Anyone seen similar issues on their ppc64le builds?
