Introduction to Bazel to build C++ and Python - Xavier Bonaventura - code::dive 2020

Abstract
Yet another build system? Why should you learn a new one?
{Fast, Correct} - Choose two
that's the motto of Bazel. In this talk I will give an introduction to the open-source build and test tool developed by Google. The first major release was published by the end of 2019. What is so special about Bazel? It is fast, reliable, multi-platform, scalable and extensible. Everything extracted using a high-level build language similar to Python called Starlark. During the talk I will show you how to define libraries, binaries and tests for C++, as well as for Python. In addition I will show you how to combine both languages in a project and how to set up a build toolchain. At the end of the talk I will give you some ideas on extensions that can be added to fit your project and requirements.

How to specify dependency library lookup folder in bazel BUILD file? normally we give it using '-L/path/to/dependency/library' option.

Thanks! The build tutorial doesn't give this excellent overview.
