[CMake] CMake Java Support

[Allen D Byrne]

Andreas,
Thanks for providing these files! I have finally been able to progress on converting our java product to cmake.
I have one suggestion:

Add to the add_java function the classpath for the target;

    set(${_TARGET_NAME}_CLASSPATH ".${CMAKE_JAVA_INCLUDE_PATH_FINAL}/${_TARGET_NAME}.jar" PARENT_SCOPE)

I needed this on linux (uses ':' in classpath not ';' ) to do an add_test.

Also two questions: 
How do I get the jar files into an output folder for build/test (not install task)?

After I build my JNI Library with normal C process how do I connect the java JAR  to use the library? I'm not sure how to use INSTALL_JNI_SYMLINK?

Allen
