Also on macOS Mojave on a new mac, I had the same issue, but `macOS_SDK_headers_for_macOS_10.14.pkg` wasn’t there. I got it by downloading and running [this](https://download.developer.apple.com/Developer_Tools/Command_Line_Tools_macOS_10.14_for_Xcode_10/Command_Line_Tools_macOS_10.14_for_Xcode_10.dmg) from the developer site. Running `xcode-select --install` might also have worked.

Then I had to [fix some tests](http://viewvc.slicer.org/viewvc.cgi/Slicer4?view=revision&revision=27525) but then the compile completed.

Slicer runs, but it’s not usable. This is with Qt 5.11.2 on a macbook pro retina, with the resolution set as “best for display”.
