[R-pkg-devel] Github action setup for R 4.2.0 on Windows?

[Duncan Murdoch]

Today a Github actions check of rgl failed on Windows with R 4.2.0 and 
this error:

If I'm interpreting it correctly, the problem is that the Freetype 
includes are not installed.  I don't have a good local Windows build 
system running currently, but I believe Rtools42 includes Freetype, so 
this makes it look as though the Github build doesn't have a proper 
install of Rtools42.

The script I was using is here:

 
https://github.com/dmurdoch/rgl/blob/master/.github/workflows/R-CMD-check.yaml

Can anyone spot what I'm doing wrong, or is it just a matter of waiting 
until something else is updated on Github?
