[vtkusers] vtk installation CMake java problem

[Sebastien Jourdain]

Hi Jim,

The red mean, "New option available base on your previous choice".
For the BUILD_SHARED_LIBS = OFF, I have quite some doubt. That would mean
you want a static build with the Java wrapping. And to my knowledge, that
is not possible with Java.

Otherwise, to have VTK works within the Eclipse development environment, I
usually need 2 things:
- Add the vtk.jar to the classpath of my project
- (on Windows) expend the PATH env var to add the directory that contains
all the dll of VTK. If you pick the option to package VTK for Java, then
you will need to unzip the native JAR file and point to the content of its
directory.
