What it does

Downloads the current upstream x86_64 and aarch64 tarballs.
Derives the version from both tarball root directories and requires them to match.
Renders a concrete spec file with that version before invoking rpmbuild.
Repackages the prebuilt binaries into an RPM.
Removes the upstream auto-update manifest so RPM remains the update path.
Sets resources/package-type to rpm.
Builds binary RPMs for x86_64 and aarch64, while still forcing SRPM generation to target x86_64 so COPR source builders stay consistent.
Supports COPR SCM builds through .copr/Makefile.

Local builds

Build a source RPM:

make srpm

Build a binary RPM and source RPM:

make rpm

Artifacts are written to dist/.

COPR

Use COPR's SCM source type with:

Clone URL: this repository
Spec template: SPECS/element-desktop.spec.in
SRPM build method: make srpm
Enable x86_64 and aarch64 binary chroots for this package

COPR will invoke .copr/Makefile, which calls the same SRPM generation script used for local builds. That script downloads the upstream tarball during the SRPM stage, so no vendored source archive is required in git.
