[CMake] SWIG, Java and CMake

[Daniel Blezek]

We are using SWIG in the SimpleITK project (
https://github.com/SimpleITK/SimpleITK for the interested ) to generate Java
wrappings for our library.  The problem I¹m having is how to educate CMake
about Java.  SWIG generates a known-only-at-compile-time set of Java code.
CMake prefers to know in advance what source code needs to be compiled.

So far, our Java support has been cobbled together and is rather fragile,
and I¹m trying to make it more robust.  I pulled in the UseJava.cmake code
from the CMake repo (it¹s not in a release yet), but the add_jar command
likes to have a list of .java files.

Any suggestions about how to have CMake handle generated files like this?

Thanks,
-dan
