Save the CMake executable in our MM config file. (#9563)

  - This allows us to provide a non-default CMake executable from to our
    autoconf config or CMake config. OpenModelica now remembers this
    selection and uses that exact CMake executable for all its internal
    uses as well.

  - Improves #9509.
