The last few days (possibly correlating with this commit or with some
other cmake change) my out-of-tree cmake build on OSX has failed to
launch the qt gui:

When I launch it by hand:

---
objc[16899]: Class NotificationReceiver is implemented in both
/usr/local/opt/qt5/lib/QtWidgets.framework/Versions/5/QtWidgets and
/Users/eapache/src/wireshark.org/build/run/Wireshark.app/Contents/Frameworks/QtWidgets.framework/Versions/5/QtWidgets.
One of the two will be used. Which one is undefined.
objc[16899]: Class QCocoaPageLayoutDelegate is implemented in both
/usr/local/opt/qt5/lib/QtPrintSupport.framework/Versions/5/QtPrintSupport
and /Users/eapache/src/wireshark.org/build/run/Wireshark.app/Contents/Frameworks/QtPrintSupport.framework/Versions/5/QtPrintSupport.
One of the two will be used. Which one is undefined.
objc[16899]: Class QCocoaPrintPanelDelegate is implemented in both
/usr/local/opt/qt5/lib/QtPrintSupport.framework/Versions/5/QtPrintSupport
and /Users/eapache/src/wireshark.org/build/run/Wireshark.app/Contents/Frameworks/QtPrintSupport.framework/Versions/5/QtPrintSupport.
One of the two will be used. Which one is undefined.
QObject::moveToThread: Current thread (0x7fcaf9d1c9f0) is not the
object's thread (0x7fcaf9c1e380).
Cannot move to target thread (0x7fcaf9d1c9f0)

On Mac OS X, you might be loading two sets of Qt binaries into the
same process. Check that all plugins are compiled against the right Qt
binaries. Export DYLD_PRINT_LIBRARIES=1 and check that only one set of
binaries are being loaded.
This application failed to start because it could not find or load the
Qt platform plugin "cocoa".

Available platform plugins are: cocoa.

Reinstalling the application may fix this problem.

So it looks like the build is now copying files into the frameworks
folder and the app doesn't know which lib to pick?
