From 0eb00ed700c472f005de35d96c72a9b54cd4c2c2 Mon Sep 17 00:00:00 2001 From: Berthold Stoeger Date: Thu, 4 Apr 2019 22:00:38 +0200 Subject: Cleanup: provide our own qOverload<> implementation. This is only in Qt 5.7 and therefore can't be used in Qt 5.5 and 5.6 builds. Moreover, we can't simply reuse Qt's version owing to licensing concerns.
