There's a couple of angles here:
- if your CMakeLists.txt tries to download something, it will fail.
- if you expect packagers to download additional files then put that in GIANT
LETTERS in several places; also make any attempted download fail gracefully
with a useful message ("additional source files are needed ..").
It's not that unusual for a single package to require multiple source tarballs
or additional source files, but you need to support it *and* be clear about
what's needed.
Koko does the right thing in accepting an already-downloaded file; it'd be
nice to fail more gracefully, and you should make it more prominent rather
than hidden on line 106 of CMakeLists.txt in a subdirectory.
