FindMatlab: incorrect path for MCR

With an MCR installation, my find_package(Matlab) adds the version of the installation at the end of MATLAB_ROOT_DIR, resulting in this type of error:

-- [MATLAB] Extracting MATLAB versions with registry view args 'VIEW;TARGET'
[cmake] -- [MATLAB] Getting MATLAB roots with registry view args 'VIEW;TARGET'

My Matlab MCR installation is at C:/Program Files/MATLAB/MATLAB Runtime/R2022b, not C:/Program Files/MATLAB/MATLAB Runtime/R2022b/v913. I found the line in findMatlab.cmake that adds the version to the MATLAB_ROOT_DIR.

      # remove the dot
      string(REPLACE "." "" _matlab_current_version_without_dot "${_matlab_current_version}")

Unfortunately, deleting this line causes a different error :
