build.yml

# This configuration is used to build and test on GitHub Actions only.
# It is not the same configuration that is used by Google DeepMind to create release binaries.
# The "official" binaries are built with Clang 13 on all platforms, and are linked against libc++
# on Linux.
#
# We set CMAKE_INTERPROCEDURAL_OPTIMIZATION=OFF here to reduce build time.
# It is highly recommended that this is set to ON for production builds.
