When adding the library in Cmake (target_include_directories) as submodules, there are conflicts with the compiler detection and your version file under Qt 6. Under Qt 5 the problem does not exist.
Therefore here is a PR that renames your version file to ".version". There are no changes in the core of your library by this PR.
