When CMake generates the buildsystem in that build tree it will read the query files and write reply files for the client to read. The file-based API uses a <build>/.cmake/api/ directory at the top of a build tree. The API is versioned to support changes to the layout of files within the API directory.

The possibilities are endless. as you can use this concept to pull the version number from your build system; such as git and use that version number in your project.

file (READ <filename> <variable> [OFFSET <offset>] [LIMIT <max-in>] [HEX]) Read content from a file called <filename> and store it in a <variable>. Optionally start from the given <offset> and read at most <max-in> bytes. The HEX option causes data to be converted to a hexadecimal representation (useful for binary data).

Dec 15, 2021 · CMake supports two files that allow users to specify common configure, build, and test options and share them with others: CMakePresets.json and CMakeUserPresets.json. Use these files to drive CMake in Visual Studio and Visual Studio Code, in a continuous integration (CI) pipeline, and from the command line.

The other direction can be done too; you can read in something (like a version) from your source files. If you have a header only library that you'd like to make available with or without CMake, for example, then this would be the best way to handle a version.
