[Paraview] gpu_shader4 extension is not supported

[Patrick Begou]

Thanks a lot Burlen, all is running fine now with this setup for mesa on the 
front-end.
With Paraview, I had to add some parameters for ffmpeg-3.3 libraries that were 
not automaticaly loaded and set LD_LIBRARY_PATH to load llvm is a separate 
directory from mesa but all runs fine now:
export LD_LIBRARY_PATH=/share/apps/mesa/17.0.6-x11-swr/lib/:$LD_LIBRARY_PATH
export LD_LIBRARY_PATH=/share/apps/llvm/4.0.0/lib:$LD_LIBRARY_PATH

and for cmake:
cmake ............
    -DPARAVIEW_ENABLE_FFMPEG=ON \
    -DFFMPEG_ROOT=/share/apps/ffmpeg-3.3-GCC485 \
-DCMAKE_EXE_LINKER_FLAGS="-Wl,-rpath-link=/share/apps/ffmpeg-3.3-GCC485/lib:/share/apps/llvm/4.0.0/lib:/share/apps/mesa/17.0.6-x11-swr/lib 
-L/share/apps/ffmpeg-3.3-GCC485/lib -lswresample -lavutil -lavformat -lavcodec 
-lswscale -lavdevice -lavfilter" \
    -DVTK_FFMPEG_AVCODECID=ON \
.......
