As a complete novice at this cmake stuff, I read with interest   the files 
within your link and your post also.   I have dabbled with java   and have a 
little interest in  dabbling with openJDK.
But I know of no recipe for building openJDK  (there used to be one   at   
( http://cblfs.cross-lfs.org/index.php/OpenJDK    ) but no more.    And this 
site  (  http://openjdk.java.net/ )   is not particularly helpful; .  
Have you tried building openJDK with  cmake?  Or do you know of anyone who 
has? Or would you like to give  your java/c{c++}/cmake-macros a test run   and 
let us stand on your shoulders?
