SECCOM 2017 - Conan.io o gerente de pacote para C e C++
The document presents a lecture by Uilian Ries at Seccom 2017 about using Conan, a C/C++ package manager. It covers the basics of package management, including downloading dependencies, creating recipes, and setting up build configurations for C++ projects. Examples include validating emails using Boost Regex and detailed steps for creating, testing, and managing packages with Conan.
