Add option for specifying an epoch in DEB and RPM CPack generators
Both DEB and RPM support specifying an "epoch" as part of the version of a package. CMake currently does not support this which makes it difficult to create packages that can update a system package with an epoch other than 0.
I currently work around this issue by using fpm but it would be nice if CMake would support specifying an epoch directly.
