VTK is failing on libraries in IO/FFMPEG

libraries not found (missing -L${EXTERNALS})

• -lavformat
• -lavcodec
• -lavutil
• -lswscale

@aashish24 do you know what is happening with IO/FFMPEG build with gcc 5.2.1? I tried to use LDFLAGS without success, if I change link.txt and add -L.../Extenals/lib it compiles correctly.

@dnadeau4 can you send me your CMakeCache.txt

After fixing VTK link problem, I had to recomiple PyQt4 and everything worked.

[dnadeau4]

I created a patch for "ncurses" and update cmake to "3.4.0-rc2". I rebuild and everything worked fine.

Will try a pull request to see what happens on different machines.

@dnadeau4 as promised here is the branch: CDAT/VTK#12

I will need to create a new branch for UV-CDAT as well (will do today). Will need your help with review.
