The telegram developers made great progress in making packaging Telegram
Desktop a pleasant experience for Alpine Linux.
- There is now a full tarball available that includes all gitmodules
that before were all checked out via tarballs in the source= variable.
- There is now support deciding whether to use system packages and
linking it to the Telegram binary instead of statically linked checked
out versions in the source tree.
- The build system is now cmake, which is much better than the previous
GYP meta build-system mess.
Overall the change from the old to the new system reduced Alpine Linux's
load by 834 lines.
