# flatpak-builder manifest for repackaging the official O3DE Linux .deb as a Flatpak.
#
# The workflow (and scripts/build.sh) download the latest o3de_*.deb to ./o3de.deb
# next to this manifest before building, so the manifest itself never needs editing
# when a new version drops.
#
# Why the SDK is the runtime (not just the sdk): O3DE compiles game-project code at
# runtime and ships only a *build toolchain* dependency list (clang/ninja/cmake/
# pkg-config + -dev libs). Those live in org.freedesktop.Sdk, so we run against it.
