Alan, you had said in your original post:
"Using find and xargs -0 grep I have looked in both 3.7.2 and 3.9.0
source code for any mention of CMAKE_Java_CREATE_SHARED_MODULE, and it
just does not exist."
Try searching for "_CREATE_SHARED_MODULE" instead... it's combined in code with
the name of the language.
Just a hint about how to further the investigation. I'm curious what the result
will be, but don't have time right now to dig in on something peripheral to my
main to do list.
