docs/data/reusables/code-scanning/autobuild-add-build-steps.md

If autobuild fails, or you want to analyze a different set of source files from those built by the autobuild process, you'll need to remove the autobuild step from the workflow, and manually add build steps. For C/C++, C#, Go, and Java projects, {% data variables.product.prodname_codeql %} will analyze whatever source code is built by your specified build steps.
