Thanks you very much, that got me mostly there.
In cmake versions older than 3.13 this apparently has to be

actions echo
    cmake -H"$(>:D)" -B$(<:D)
    cmake --build "$(<:D)"

(no space between B and the path and -H instead of -S).

Now I only need a way to properly hook this up, so it gets only re-run, if one of the cmake files change.
