1October 3, 2023 2 Libraries: A First Step Toward Standard C++ Dependency Management Bret Brown, C++ Infrastructure Lead, Bloomberg Bill Hoffman, CTO, KitwareHello! Welcome! Bret Brown C++ Infrastructure portable as the code they contain! ● ✓ Projects should be “cattle,” not “pets”! 7Why dependency management? 8Consensus: Managing dependencies == way too hard Q: Which of these do you find frustrating names: jsonlogConfig.cmake Jsonlog-config.cmake # ... CMake gives you some dependency management tips here ... 13 Aside: Coloring and bolding added for emphasisMotivation: What would we design

USB support is not limited to certain device cate- gories. For details, see chapter 3.10.1, USB settings, page 53. – Hardware compatibility. VirtualBox virtualizes a vast array of virtual

Live Migration and Resource Monitor are additional modules currently in the process of being added 4.2, Authenticating at web service logon, page 25. 2.1.1.4 Object management The current OOWS for JAX-WS has certain memory management related limitations. When you no longer need an object, call its the creation of such an object by calling IWebsessionManager::getSessionObject(). More complex management tasks might need mul- tiple instances of ISession, and each call returns a new one. 47 3 Basic
