qt5-qt3d complains about system assimp missing

[Michael A. Leonetti]

I just upgraded to Catalina (so many regrets).

My qt5 installation keeps complaining about missing linking files so I 
am trying to reinstall and qt5-q3d complains about missing system-assimp.

Is there a variant I'm missing that I can disable?
