It looks like the problem is related to which version of CMake you use. Ubuntu 16.10 supplies CMake 3.5.2. Steam-Runtime ships a version that is way too old, so I built and used the latest stable CMake version, 3.6.3. Using 3.6.3 seems to always trigger this problem with the Swift build. I tested it both ways: 1. I changed Ubuntu 16.10 to use CMake 3.6.3 and the build broke in exactly the same way I described. 2. In Steam-Runtime, I built/used CMake 3.5.2 instead, and the build completed. I still don’t know specifically what the build script bug is. This is going to need to be fixed eventually if all newer versions of CMake lead to a broken build process.
