Salon E-G

In this presentation, we will describe how we manage to develop multi-physics applications with a software stack deployed with Spack.

We will describe how we have designed a workflow, first using Spack features for development, such as "setup," "dev-build," and "develop." And how we ended up creating a Spack plugin to generate custom CMake presets.

CMake presets are a portable way to set up CMake configurations. They can describe several configurations. And they can be exploited by different tools, from the command line to IDE.
Generating these presets from Spack concretizations allows users to exploit their classical environment, benefiting both from a correct installation of their dependencies as well as advanced features of the IDE that do not need to integrate explicitly with Spack.

We will present our journey between the different spack solutions, the development of a CMake "preload cache"-based answer, and we will illustrate use cases of why we ultimately switched to CMake presets.
