In !2305 (closed) and an earlier mailing list thread, it has been proposed to add per component versions for multi-component packages. The rationale for this is that the CMake project could be an umbrella project building a number of projects each with their own package rather than a single coherent suite of related projects' packages. !2305 (closed) only addresses DEB packages, but an analogous feature for RPM would seem just as relevant. The IFW package generator already supports per component versions, which are a key part of its component update functionality. Should we be seeking to add support for per component versions across all package generators that support components?

If the answer to the above is yes, then the natural follow-on question is whether such support should be added to the CPackComponent module so that the per component versions can be defined in one place instead of having to set a variety of packager-specific variables.
