[Paraview] -std=c++11 for a single directory?

[Robert Maynard]

You need to force cache the CMAKE_CXX_FLAGS variable with c++11 in the
CMakeLists.txt for the plugin.

You should be aware of the potential ABI incompatibilities in the
c++11 and c++98 libstdc++ library (
https://gcc.gnu.org/wiki/Cxx11AbiCompatibility ). Plus the fact this
won't work with clang as they are ABI incompatible.
