Why is that so? (I pose this question just for improving my understanding of the whole process.) If you manually download an SDK version (so from The Document Foundation (TDF) site) that is compatible with the LibreOffice that is in the repository of a given Linux distribution, shouldn't that also work?

I did grep through the Ubuntu repositories and I found:

libreoffice-dev - office productivity suite -- SDK -- architecture-dependent parts

That looks quite promising.

Thanks for the tip! Perhaps someone else can confirm this? If the semantics of "user installation" is not clear to you, then it is definitely not clear to a humble beginner in LibreOffice extension development (like me ;-( ).
