License of the output of the Projucer

Dear community,

I’d like to publish a work derived from JUCE as Open Source project under the GPLv3. Now, I would like to know how to treat the output generated by the Projucer (such as the “…Processor” and “…ProcessorEditor” source files). Are they themselves to be regarded as copyrighted with copyright on JUCE side? Do I actually need to signify having changed these files according to my needs (as stated in GPLv3)?

Or is it sufficient to put my own GPL’ed copyright notice into them? Note that they also import JUCE headers - is it ok, given that I supply the source files on GitHub, to simply import them, or does that effect the file importing those headers to be under the copyright of JUCE as well?

Thanks in advance :slight_smile:
