libQt5Qml port?

[Gary Aitken]

11.4-RELEASE-p3

Trying to build cad/freecad:

===>   qt5-designer-5.15.2_1 depends on shared library: libQt5Core.so - found (/usr/local/lib/qt5/libQt5Core.so)
===>   qt5-designer-5.15.2_1 depends on shared library: libQt5Qml.so - not found
===>   qt5-designer-5.15.2_1 depends on shared library: libQt5Qml.so - not found

Can someone tell me which port supplies this library, or at least how to find
out?  I tried using libQt5Qml.so in the keyword search on freshports but got
no hits.
