Then perhaps people asking about how to build on PyQt 5 should be pointed
to one of these more representative modules. I remember that when I was
doing the calibre transition to Qt 5 I also came across the advice to
look at QScintilla, and rather than trying to adapt that beast, I wrote
my own minimal build logic that does what calibre needs.

Sounds fine to me. I was just trying to help the OP, since from
experience, trying to adapt QSintilla's build system is not a task to be
taken on lightly. Even just having some officially sanctioned method of 
gathering information like runtime paths and compiler flags would be
helpful. Essentially, something like qmake -query
