I don't know of a way directly. The format you mentioned here works, as if a
tag is added, you can easily switch to git describe without having to add an
epoch. If you want to match upstream closer, you can do it by parsing
CMakeLists.txt directly, something like
awk 'match($0,/set\(PROJECT_VERSION ([0-9.]*)/,a) {print a[1];}' CMakeLists.txt
to get you the project version, then add the rest.
