FWIW this language support is quite limited, is not well tested,
and has long been superseded by `UseJava.cmake`. I suggest porting
away from it in PLplot. That will fix this too.

Hmm. That causes swig_add_library's call to add_library to include
the generated .java source file as a source (since it is the
output of a custom command we want to run).
However, with `enable_language(Java)` CMake thinks it is supposed
to compile the .java file as part of the (module) library. That's
why it looks for CMAKE_Java_CREATE_SHARED_MODULE.
Please try the patch below.
