Hi, You could make it a non-cache variable and manage the caching yourself. The cache is your version.cmake. Before including it, check if the variable is set and update your version cmake file, possibly with configure_file(). After that, unset() the cache variable and include your cmake file, this having a non-cache variable. Add the cmake file to the list of dependent files to let cmake run when that file changes.
