Pros
Pro Powerful language
You can write code for your build system in Ruby. While not my choice for general programming, Ruby is powerful and expressive. Given some knowledge of Ruby, you can create powerful Rake extensions that result in your average target only needing a few lines in the rakefile in spite of having complex behaviors (Is the library for public consumption, or only for use within the current repo/tier? Compile certain files on certain platforms? Link to libraries published from other repos? etc.).
Pro Cross-platform
Linux, macOS, FreeBSD.
Pro Intuitive syntax and workflow
Much simpler than multi-tier build systems, like Make and Ninja.
Pro Code Completion
Works with many IDEs, including Visual Studio Code.
Cons
Con Slooooow
For large codebases or with complex extensions, Rake can become quite slow. I'm aware of one codebase on which it can take 15 minutes to determine that no changes have been made and no recompilation is necessary.
