This is amusing:

Interesting stats:
cjdns - 40k LoC* - clean build in 40 seconds - 1k LoC/sec
xwiki - 800k LoC* - clean build in 60 minutes(?) - 222 LoC/sec
Cjdns build is still embarrassingly slow because cmake invokes the
linker far more often than necessary.
* LoC is the total line count for every source file in the project.
