Summary

No Magic Answer

Managing libraries in C++ is more tricky than some other languages.

While package managers make it easier, you still need to understand what you’re building.

A Few Good Libraries

Main advice for libraries:

• As few as possible
• As high quality as possible

Ways to Use

• Easiest - header only
  • just include directly in your source code
  • use cmake include_directories()
  • compile it in
• use packages from package manager
  • use cmake to find_package
  • set variables to your installed version
• use build system to build everything
  • you control ALL flags
  • cmake does find_package on things you just compiled

Git Submodule Anyone?

• git submodule
  • If all dependencies are cmake’d
  • Put each project in a git submodule
  • Cmake can configure whole project
  • Not really used on this course
