[vtkusers] Compiling VTK on OSX with .jnilib extensions

[Michael Jackson]

If you have applied Apple's latest java update there seems to be a  
problem with a symlink to the jni.h header. There are a few recent  
posts (as recent as yesterday) on this list with the solution. Maybe  
that will help you.

Here is the quote from that email:
----- david.gobbi at gmail.com Said........
Ah, reading what you said about symlinks in your email, I realized
that if people just copy files between the two directories that I
mentioned in my email, they will copy over the symlinks instead of
copying to the directory that the symlinks point to.  To be clear,
what people should do is copy

/Developer/SDKs/MacOSX10.6.sdk/System/Library/Frameworks/ 
JavaVM.framework/Versions/CurrentJDK/Headers/*

to

/System/Library/Frameworks/JavaVM.framework/Versions/CurrentJDK/Headers/

or just change CMakeCache.txt to use the SDK's include directory.
