Git is always used to generate the KiCad version string using the
command `git describe --dirty`. This gives a more concise and
accurate version string than the previous method. When git is not
available, the version string defaults to the value defined in
KiCadVersion.cmake. It is imperative that moving forward that the
default version string be updated the commit following a git tag
so that when git is not available, the last known commit following
a git tag will at least give some usable information about which
development branch of KiCad was used for a build.
