Esprit d'escalier.  We could change GenericDataDir in QStandardPaths to be:

     "~/Library/Application Support/Qt5", "/Library/Application Support/Qt5"

That would work for ALL applications that use Qt5 and QSP, regardless of origin,
and would be a more "correct" usage of Apple OS X by the Qt 5 libraries.

I was thinking the same.  I come from an environment where everything had to be "uniquified":
large databases with thousands of application programs.  And we already have the example,
in Open Source and Macports, of ECM being an ambiguous acronym… ;-)
