[Paraview] Problem linking Cocoa pqWidgets

[Eric E. Monson]

Berk -- out of curiosity, then, is your Qt 4.6 built for both i386 and x86_64 architectures, and using Cocoa?

It doesn't necessarily make sense, but since I don't get the grayed out filters on my laptop which was using an older version of CMake (2.9.20091007) -- so it linked a bunch of PV libraries with additional OS X frameworks -- is it possible that with more recent CMake there are some other dependencies which are not being linked in, don't get caught at compile time, but are missing at run time?

Anyway, as long as someone can put in that extra Cocoa line for pqWidgets, at least that will build with CVS CMake.

Thanks,
-Eric
