When a CMake project needs a placeholder icon, installer banner, or diagram for documentation, waiting on a designer can stall a release. A lightweight AI image workflow can fill that gap for early drafts.
Anyone who has shipped a CPack-based installer knows the moment: the build system, the packaging scripts, and the CI pipeline are all solid, but the project still needs a background image for the NSIS or WiX installer, an icon for the desktop shortcut, or a simple diagram for the README explaining the build graph. Design work is usually the last thing on a build engineer’s list, and pulling in an actual designer for a placeholder asset often isn’t worth the coordination overhead.
A practical workaround is to treat these assets the same way you’d treat a throwaway prototype build: generate something rough, get it into the pipeline, and swap it later if the project grows. That usually means either hand-drawing something quick in a vector tool, reusing an existing open-source icon set, or generating a draft image from a text description. The generation route is fastest when you need several variations quickly, for example testing three different color schemes for an installer banner before committing to one in CPACK_NSIS_MUI_ICON or similar variables.
For that kind of early-stage visual exploration, a tool like Nano Banana 2 Lite fits the “draft, don’t finalize” step: it’s a third-party, independent site for prompt-based image generation, useful for sketching mockups, icons, or diagram concepts before a real asset pipeline takes over. Worth noting it has no connection to CMake tooling itself and won’t touch build scripts or packaging logic.
The limitation is real: generated images are a starting point, not production-ready branding, and licensing/attribution should be checked before anything ships in a public installer or repo. For internal documentation drafts or quick presentation graphics, though, it can save the back-and-forth that usually happens when someone just needs “a picture that looks roughly right” before the actual design work begins.
