Comment (by michaelld):

 If this issues is still relevant, a file that would be useful to attach to
 the ticket is `$(port work qt5-qt3d)/qt3d*/config.log` ... it should show
 the error associated with either finding or building or linking against
 assimp. I saw this issue when trying to coerce Qt3d to build on ARM64 ...
 turns out the test was building using x86_64, not ARM64, because of some
 esoteric Qt base setting. Not difficult to fix once I was able to find the
 error in this file!
