Creator can't parse CMake version at first

1. Go to "Edit" -> "Preferences..." -> "CMake" -> "Tools".
2. Add cmake from the Qt Online Installer's Tools directory.
   Instead of a proper version number, the dialog reads "Version not parseable":
   
3. Unselect the new CMake tool, e.g. by selecting a different, autodetected CMake tool.
4. Unselect the new CMake tool again.
   The dialog displays the correct version number.

This version number should already be displayed after step 2.
