You may want to have a look at the new FetchContent
<https://cmake.org/cmake/help/latest/module/FetchContent.html> module added
in the 3.11 release (currently in release candidate stage). It already
brings a production-tested dependency downloading system, but still leaves
how to build those dependencies up to the project. It may form a good basis
for the GSoC work and I can probably answer questions related to that
module if needed.

Also consider other existing systems which may have already sufficiently
solved this problem for you or at least be useful for showing how aspects
of the work could be done. There are a number of popular systems worth
checking out that are often mentioned on this list, including hunter,
Spack, cget and others (I'll let the various stakeholders in the relevant
projects chime in with their views rather than me potentially misrepresent
some).
