# ----------------------------------------------------------------------------
# GitHub Actions workflow to build this application.
# Using latest Castle Game Engine ( https://castle-engine.io/ ) snapshot.
# For multiple platforms (Linux, Windows, macOS, Android).
#
# This uses GitHub-hosted runners, that is: you don't need to set up any server
# infrastructure, GitHub provides it all for free for open-source projects.
#
# See docs:
