Cannot build INLA from source on Windows

[weshinsley]

If we try and build INLA from source, we get the error message below:-

> install.packages("INLA",
                 repos = c(getOption("repos"),
                           INLA = "https://inla.r-inla-download.org/R/stable"),
                 type = "source",
                 dep = TRUE)

This is easy to work around with R 4.4 - just don't build from source, and the binary gets downloaded - if the ready-build version is available. But for users still on R 4.3, there is no matching binary of 24.05.10 in https://inla.r-inla-download.org/R/stable/bin/windows/contrib/4.3/, so install.packages tries to build 24.05.10 from source. They have to either upgrade to R 4.4, or specify version 24.05.01-1 manually, because there's a binary for that.

So the workarounds are not hard, but is seems there's a problem in the source version for building at the moment.
