+Subject: [PATCH] Re-fix QtCore resource path changing and prepare for Qt 5.13
+
+Commit 9cf8ab3b3d44ac50a1f8d4893d8f70b8aedb18b0 added the #ifdef, but
+that of course only works if you don't upgrade Qt compared to what Qt
+Creator was compiled with. Instead, attempt both paths and only do that
+if the system copy is not found.
+
+Searching the system copy is required to address Qt 5.13's configure
+option -no-mimetype-database (used by Linux distributions because the
+system copy is always present).
+
+This code will still need work to deal with Qt 5.14 changes.
