Yes. I got that working for CI by overriding with a value from the environment.
https://cirrus-ci.com/task/6191974075072512

This is right after rebasing, so it doesn't save anything, but normally cuts
build time to 90sec, which isn't impressive, but it's something.

BTW, I think it's worth compiling the windows build with optimizations (as I
did here).  At least with all the tap tests, this pays for itself.  I suppose
you don't want to use a Release build, but optimizations could be enabled by
an(other) environment variable.
