+Linux binaries can be built using Makefiles found in the `linux` folder. They expect to be built / run in the Steam Runtime "scout" environment. The built binaries are copied to a directory called "game" at the same level as the root directory for the git repository. You can set CREATE_OUTPUT_DIRS=1 while building to create the output directory structure automatically.
