Added a check in BP level for BaseDependencyTag It is not allowed to directly use BaseDependencyTag as customized user dependency tag passed down to BP since it might cause issues that different type of modules will be mixed when fetched based on Tag.
Blueprint is a meta-build system that reads in Blueprints files that describe modules that need to be built, and produces a Ninja manifest describing the commands that need to be run and their dependencies. Where most build systems use built-in rules or a domain-specific language to describe the logic for converting module descriptions to build rules, Blueprint delegates this to per-project build logic written in Go. For large, heterogenous projects this allows the inherent complexity of the build logic to be maintained in a high-level language, while still allowing simple changes to individual modules by modifying easy to understand Blueprints files.
