Hi

I seem to be running into a problem building Slicer on Mojave. Slicer builds without any errors but when I try to run it, I get the following error:

```
dyld: malformed mach-o: load commands size (34376) > 32768

2019-08-19 14:11:49.981 Slicer[92126:1188397] *** WARNING: Method userSpaceScaleFactor in class NSView is deprecated on 10.7 and later. It should not be used in new applications. Use convertRectToBacking: instead.

error: [/Users/Priya/Project/Slicer-latest/Slicer-Superbuild-Debug/Slicer-build/bin/Slicer.app/Contents/MacOS/./Slicer] exit abnormally - Report the problem.

```

Is there any log file created to investigate the problem? Details of build as follows:

Qt version: Tried 5.11 and 5.13 - same problem exists  
Mac OS: 10.14.6
