ATLAS CMake

The ATLAS software, called athena, itself is a very large project containing many packages. To help define all of the dependencies, CMake is used to manage the build process. To make a developer’s life easier, athena defines several custom macros. This lesson describes how to use these custom macros to build an user package.

Prerequisites

This assumes that you’ll have a basic knowledge of CMake, for example:

1. What out-of-source builds are
2. How to write a simple CMakeList.txt
3. How to generate a Makefile from a CMakeLists.txt

This lesson will also build on the AnalysisPayload project started in the previous ATLAS GitLab lesson.
