+This dir is used by `src/*/CMakeLists.txt` to run `git describe --match "v*"`.
+Because, if it would be run in that directory, on Windows the `--match "v*"`
+would get expanded to the `version.h.cmake` file there, causing Git to
+obviously not find any such tag. The reason is probably that on Windows the
+wildcard expansion is done on the application side and not by the shell, thus
+being performed even though CMake docs say `execute_process()` doesn't involve
+a shell. This directory is thus dedicated for that operation, *guaranteed* to
+never contain any file starting with `v` (or `V` for that matter because,
+again, HELLO WINDOWS).
+
+No matter what you do, DON'T put any files starting with `v` or `V` here, or
+hell breaks loose again.
