Hi

I have noticed several fails in macos build of my extension, maybe this is happening for others. see [CDash](https://slicer.cdash.org/index.php?project=SlicerPreview&filtercount=1&showfilters=1&field1=buildname&compare1=63&value1=Opendose)

It basically says “Unable to find executable”

For Windows and linux there is no problem at all.

macOS had a build error that resulted in Slicer not being able to run, so no extensions were able to be built either.
