Great question! Couple of small answers: i) This started as a 'proof of
concept' that aimed to be small so getting by without requiring `configure`
seemed worth a try, ii) I had seen another src/Makevars invoking compilation
of a static library in a similar (albeit non-cmake) way and iii) as we now
know about section 1.2.6 (or soon 1.2.9) 'Using cmake' has it that way too.

Otherwise I quite like having `configure` and I frequently use it -- made
from 'genuine' configire.in via `autoconf`, or as scripts in shell or other
languages.

Cheers, Dirk

PS My repaired package is now on CRAN. I managed to bungle the static library
build (by not telling `cmake` to use position independent code), bungled
macOS but not telling myself where `cmake` could live, and in fixing that
bungled Windows by forgetting to add `src/Makevars.win` fallback. Yay me.
