[cmake-developers] Support of Scala language

[CHEVRIER, Marc]

I agree. The right approach is to do an integration of Java in the same way as C or C++.
But I don’t have currently enough CMake skills to do this work.

Do you have some documentation explaining how language support is done in CMake ? And how specific behaviours of Java/Scala can be supported in CMake:
* All sources composing a jar must be compiled all at once
* A source file can produce an arbitrary number of binary files (.class) with various (and unpredictable) names.
