 In addition, your host system will need to be able to run Wine in both 64- and

+The openal-soft build system requires cmake 3.0.2 or later, which is newer than
+the Steam runtime SDK provides. You will need to build and install a newer
+cmake into each of the runtimes. For convenience, the build_proton.sh script
+will attempt to use cmake from ~/opt32/bin/ and ~/opt64/bin/, if available.
