[vtkusers] Mac OS X, Java guru needed, please.

[Mike Jackson]

OK.. found the problem in the build. When compiling against java,  
somewhere in the link libraries must be "-framework JavaVM"

I manually added that to ${ProjectBinaryDirectory}/CMakeFiles/ 
vtkRenderingJava.dir/link.txt and reran make and I am at least  
getting farther now..

As far as putting this somewhere in ccmake I am not sure.. I don't  
want _ALL_ my libs to link aganst the JavaVM so maybe there is a  
setting somewhere that says if you are linking against Java then add - 
framework JavaVM to the list..

Someone from Kitware want to chime in....

Thanks
