Subject: [PATCH 1/2] BUG: Link the shared StealthLink library on Linux

On Linux PlusDataCollection linked libStealthLink.a. The static archive
carries none of the SDK's own dependencies, so the boost symbols it
references are left unresolved and linking PlusLib fails with:

  undefined reference to `boost::system::system_category()'
  undefined reference to `boost::system::generic_category()'

libStealthLink.so records those as DT_NEEDED, so linking the shared
library instead resolves them without having to enumerate the SDK's
bundled boost by hand.

Also install the shared library alongside the executables, matching what
the WIN32 branch already does. Since both branches install the same file
it is hoisted out of the platform conditional.

Subject: [PATCH 2/2] COMP: Remove unused vtkImageViewer2 include from
 ViewSequenceFile

ViewSequenceFile.cxx includes vtkImageViewer2.h but never uses
vtkImageViewer2; the include line is the only occurrence of the name in
the file, and it is the only occurrence in the file's entire history.

It is also the only thing in the target that reaches into VTK's
InteractionImage module, which ViewSequenceFile does not link, so it
compiles only when that module's include directory happens to arrive
transitively. Where it does not, the build fails with:

  ViewSequenceFile.cxx:17:10: fatal error: vtkImageViewer2.h: No such file or directory

Removing the include drops the undeclared dependency rather than linking
a module whose symbols are never referenced.
