+\title{Workshop Modern C++ build environment}
+\author{Bart Beumer (bart.beumer@alten.nl)}
+\institute{Alten}
+\date{2025-07-29}
+

+\begin{document}

+\begin{frame}
+\titlepage
+\end{frame}
+
+
+\begin{frame}{Rationale}
+Using modern tools in combination with C \& C++ we can describe the build environment, 3rd party libraries and executables to build.
+
+We will be able to create a highly reproducable build environment regardless of the OS running on the developer PC (as long as it can run docker).
+
+\vspace{5mm}
+
+This workshop aims to demonstrate how to create this build environment, how to use the tools, introduce ourselves to this way of working using included demonstration projects.
+\end{frame}
+
+
+\begin{frame}{Tools}
+We will be using a combination of tools, each having their own purpose.
+\begin{itemize}
+ \item Dev containers \footnote{\url{https://containers.dev/}}
+
+ \begin{quote}
+  A development container (or dev container for short) allows you to use a container as a full-featured development environment.
+ \end{quote}
+
+ \item Conan \footnote{\url{https://conan.io/faq}}
+
+ Open source, decentralized and multi-platform package manager.
+
+ \item CMake \footnote{\url{https://cmake.org/about/}}
+
+ \begin{quote}
+  ... an open source, cross-platform family of tools designed to build, test, and package software.
+ \end{quote}
+\end{itemize}
+\end{frame}
+
+
+\begin{frame}{Dev containers}
+Solves the problem of having an encapsulated environment containing all tools, files, configuration that makes up the development environment.
+
+\vspace{5mm}
+
+Supported by multiple tools like:
+\begin{itemize}
+ \item Visual Studio Code \footnote{\url{https://containers.dev/supporting}}
+ \item IntelliJ IDEA \footnote{\url{https://blog.jetbrains.com/idea/2024/07/using-dev-containers-in-jetbrains-ides-part-1/}}
+ \item GitHub codespaces \footnote{\url{https://docs.github.com/en/codespaces/about-codespaces/what-are-codespaces}}
+\end{itemize}
+\end{frame}
+
+\begin{frame}{Dev containers}
+ We need the following files:
+ \begin{itemize}
+  \item Dockerfile
+  \item devcontainer.json
+ \end{itemize}
+
+\end{frame}
+
+
+\begin{frame}{Dev containers}
+ Using docker compose we create the entire container.
+ \lstinputlisting[keepspaces,firstline=1, firstnumber=1]{../.devcontainer/Dockerfile}
+\end{frame}
+
+
+\begin{frame}{Dev containers}
+ A devcontainer.json contains metadata used by tools.
+ \lstinputlisting[firstline=1, firstnumber=1]{../.devcontainer/devcontainer.json}
+\end{frame}
+
+
+\begin{frame}{Dev containers}
+We will experiment with these files during the workshop.
+\end{frame}
+
+
+\begin{frame}{Conan}
+\begin{quotation}
+ Conan is a package manager for C and C++ which aims to solve some very common and difficult challenges.\footnote{\url{https::/conan.io/faq}}
+\end{quotation}
+
+\begin{itemize}
+ \item Conveniently depend on 3rd party packages and use them.
+ \item Automates the process of downloading, building \& deploy for further use.
+ \item Provide a mechanism to use libraries.
+\end{itemize}
+\end{frame}
+
+
+\begin{frame}{Conan}
+A simple text file can be used to configure dependencies on packages.
+\lstinputlisting[language=make]{example_conan.txt}
+\end{frame}
+
+
+\begin{frame}{Conan}
+We will experiment with these files during the workshop.
+\end{frame}
+
+
+\begin{frame}{CMake}
+ \begin{quote}
+  CMake is an open source, cross-platform family of tools designed to build, test, and package software. CMake gives you control of the software compilation process using simple independent configuration files. Unlike many cross-platform systems, CMake is designed to be used in conjunction with the native build environment.
+  \footnote{\url{https://cmake.org/about/}}
+ \end{quote}
+ \begin{itemize}
+  \item Good documentation and tutorials provided.\footnote{\url{https://cmake.org/cmake/help/latest/guide/tutorial/index.html}}
+  \item Tools run locally on a system.
+\end{itemize}
+\end{frame}
+
+
+\begin{frame}{CMake}
+Using files we can describe libraries, executables, the (external) dependencies they have.
+\lstinputlisting[language=make]{../src/hello_world/CMakeLists.txt}
+\end{frame}
+
+
+\begin{frame}{CMake}
+We will experiment with these files during the workshop.
+\end{frame}
+
+
+\begin{frame}{Workshop}
+\begin{multicols}{2}
+Lets start with opening our IDE and our project folder.
+
+\includegraphics[width=0.45\textwidth]{vscode_empty}
+
+Quickly after opening the folder we get the following question:
+
+\includegraphics[width=0.45\textwidth]{vscode_folder_contains_devcontainer}
+
+VS Code will build the container if needed and start using it.
+\end{multicols}
+\end{frame}
+
+
+\begin{frame}{Workshop}
+The dev container has been built, now we need to let conan work and fetch and build dependencies.

+\begin{frame}[fragile]{Conan: important commands}
+\begin{verbatim}
+pip install conan
+\end{verbatim}
+We use the python package manager to install conan. (part of Dockerfile)
+
+\begin{verbatim}
+conan profile detect
+\end{verbatim}
+We let conan detect compilers and tools for which it can use. (part of Dockerfile)
+
+\begin{verbatim}
+conan install
+\end{verbatim}
+While in the project working directory, download packages, compile them, generate CMake environment. (was run using vs code)
+
+After that we can use CMake as we would normally.
