Detailed Description

Version information is pulled from the local git repository during the build process.

If a git repository is not found, the build system will search for a file named version.cache under the src/core directory. The version.cache file must contain key/value pairs in the format key=value with one entry per line. The build system will use the data pulled from the git repository, or loaded from the version.cache file, to generate the file version-defines.h

The build will fail if a local git repository is not present and a version.cache file can not be found.
