Adding a font to QCAD

[JohnnyP]

Mac 10.6.8

I laid out a control panel using McCAD PCB-ST.  One of the fonts I used is Futura Condensed.

I am redoing it in QCAD, but that font is not in the list of available fonts, nor is it in my fontbook.

How to add it to QCAD?  I asked on the QCAD forum.  The designer basically pointed me to google.  All  I can find there is moving fonts between computers, rather than applications.
