Add support for "far dependencies" AddVariationDependencies is used to add dependency modules that have the same variations as the depending module, but with additional variataions. It cannot be used to add a dependency that is unrelated to the depending module, for example a dependency on a code generator that needs to run on the host to generate a target source file. Add AddFarVariationDependencies, which adds a dependency on a module that contains all the passed variations, but ignores the variations of the depending module, as well as any unspecified variations on the dependency module.

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.
