@brief Generate a JNI library for a set of modules
A single JNI library may consist of the Java wrappings of multiple modules.
This is useful for kit-based builds where the modules part of the same kit
belong to the same JNI library as well.
~~~
_vtk_module_wrap_java_library(<name> <module>...)
~~~
The first argument is the name of the JNI library. The remaining arguments are
modules to include in the JNI library.
The remaining information it uses is assumed to be provided by the
@ref vtk_module_wrap_java function.

@brief Wrap a set of modules for use in Java
~~~
vtk_module_wrap_java(
MODULES <module>...
[WRAPPED_MODULES <varname>]
[JAVA_OUTPUT <destination>])
~~~
* `MODULES`: (Required) The list of modules to wrap.
* `WRAPPED_MODULES`: (Recommended) Not all modules are wrappable. This
variable will be set to contain the list of modules which were wrapped.
* `JAVA_OUTPUT`: Defaults to
`${CMAKE_CURRENT_BINARY_DIR}/CMakeFiles/vtkJava`. Java source files are
written to this directory. After generation, the files may be compiled as
needed.
* `LIBRARY_DESTINATION` (Recommended): If provided, dynamic loader
information will be added to modules for loading dependent libraries.
* `JNILIB_DESTINATION`: Where to install JNI libraries.
* `JNILIB_COMPONENT`: Defaults to `jni`. The install component to use for JNI
libraries.
For each wrapped module, a `<module>Java` target will be created. These targets
will have a `_vtk_module_java_files` property which is the list of generated
Java source files for that target.
For dependency purposes, the `<module>Java-java-sources` target may also be
used.
