# Used to determine the version for ckb-next source using "git describe", if git

# ${var_prefix}_VERSION

# ${var_prefix}_VERSION_MAJOR
|

# ${var_prefix}_VERSION_MINOR
|

# ${var_prefix}_VERSION_PATCH

# ${var_prefix}_VERSION_IS_RELEASE if patch-extra is empty.

|
|
# If git is not found, or git describe cannot be run successfully, then these
|
|
# variables are left unchanged and a warning message is printed.

# Arguments are:
|
|
# source_dir : Source directory

# git_command : git executable
