In general this is outside the scope of a build system and falls
in the domain of package management.  I do not think this approach
is a good fit for CMake's find_package infrastructure as proposed.

FYI, CMake already has some features to help people build projects
without manually installing all dependencies ahead of time.  See
ExternalProject and superbuilds for example:
