Agenda: CMake: Advanced Topics (2024-06-11)

Basics

• Basics: Boilerplate, And Executables

• Libraries, And Dependencies

• Shared Libraries (Preview)

• Installation (“Deployment”)

• Structure - Subdirectories, Dependencies, and Include Paths

• C++, Debug/Release, CMake “Programming”, Rants

• Exercise: see https://github.com/jfasch/2023-11-27/tree/main/exercise

Optional Code And External Dependencies

• “Configured” Header Files

• Optional Code: Problem Definition, OPTION()

• Optional Code, Approach 1: Optional blacklist, C Macro (Global Flags)

• Optional Code, Approach 2: Pushing Optionality Down In Module Interface

• Targets, Properties, And More

• External Dependencies

• Exercise

Testing, Code Coverage, Code Analysis

• Running Tests

• OpenCppCoverage

• Sonarqube

• Exercise

Multiplatform (And Cross) Development

• Architecture/platform specific settings: best practices, and problems to avoid

• Cross Development

• CMake: Cross Build

Code Generators

• Problems and limitations ⟶ dependencies in generated code

• Possibilities

  • Code generation through CMake itself

  • Code generation in the backend build tool

• Example: generating stubs using Mico (www.mico.org)

• Exercise

Architectural Considerations

• Common build configuration: toolchain setting (compiler versions, compiler and linker flags, commandline macros, …)

• Dependency management

• Relation with version control

• (Linux only) Shared library versioning, ABI

• Packaging and staging (preparing an installable image by installing into a staging area)
