Let cmake generate the needed version strings, so we don't
have to spend program time doing it. This simplifies the
settings manager versioning.
Also, convert some file line endings to UNIX from Windows.
A more robust fix for https://gitlab.com/kicad/code/kicad/-/issues/4015.
This will sync the git tag for this commit. This should help prevent
confusion for users who were thinking that 5.0.0-r#####-g######## was
an older version than the 5.1 branch.
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.
Define empty string variable KICAD_BRANCH_NAME that can be used as an
optional version string element. When git is used to build the version
string, this variable is set to the git branch name. It can also be
defined at configuration time as an optional string appended to the
$KICAD_VERSION variable.
Define empty string variable KICAD_VERSION_EXTRA that can be set by
the user at configuration.
The variables KICAD_BRANCH_NAME and KICAD_VERSION_EXTRA are only
appended to KICAD_VERSION if they are set. Otherwise, only KICAD_VERSION
is uses as the version string.
Update the developer building from source document to reflect the changes.
Add KiCadVersion.cmake to set the build version and branch name.
Update WriteVersionHeader.cmake to include KiCadVersion.cmake to set
the defaults in case no .git directory is found.
