I'm curious with that.
I do currently use UseJava.cmake module
https://cmake.org/cmake/help/v3.7/module/UseJava.html
for building some java bits in a globally C++ project.
I never tried enable_language(Java)
what is the status of Java support as a primary language?
I tried to find informations about that in the doc and mailing list but
didn't find much.
Could someone please point me to the appropriate place concerning this?
