Somewhat 'ditto' from here {about wanting 'cmake' to become +/-
standard tool for R packages use, *not* at all related to macOS} :

The SuiteSparse C library on parts of which our Matrix package
builds extensively  has also switched their setup to use  cmake
instead of make ... and this was actually one reason we have not
yet updated to the latest versions of SuiteSparse for the Matrix
package.

As Matrix is formally recommended, I would even be happy if
'cmake' became a +/- required OS tool for R ...
