# Workflow to build a Maiko release that is pushed to github.
# For linux:  release assets are built/pushed for X86_64, aarch64 and arm7vl.
# For macOS:  release assets are built/pushed for X86_64 and aarch64 as well as
#             a set of universal binaries.
# For Windows:  not supported
#
# Note release pushed to github automatically includes source code assets
# in tar and zip formats.

#  3 separate jobs here that can run in parallel
#
#  1.  Linux: Build a multiplatform Linux Docker file system (not saved) and use
#      results to build/push Linux release assets.
#
#  2.  MacOs:  Build maiko for MacOS (x86_64, aarch64, and universal) then create
#      and push release assets.
#
#  3. Windows: Build maiko for cygwin and SDL (x86_64).  Build is done within the
#     cygwin-maiko-builder Docker image by building a new docker files system (and
#     not a docker container) which is used to build/push Windows(cygwin) assets.
