At Bloomberg, we have thousands of independently maintained first- and third-party C++ projects built with CMake. One of the keys to achieving this scale, while also keeping engineers productive, has been leveraging one of the most underrated and underutilized features of CMake — its extensibility via its module system. Bloomberg utilizes dozens of single-purpose CMake modules to allow its tens of thousands of CMakeLists.txt files to stay declarative, flexible, future-proof, and simple -- all while using modern CMake principles!
This talk will cover what CMake modules are, how to write one using the latest CMake features, and how to package one for others to use. Importantly, this talk will also cover when *not* to write a CMake module.
If you find yourself wincing at all the repetitive boilerplate in the CMakeLists.txt across your projects, this is the talk for you!
