I think this is the pertinent error: > make: cargo: Command not found
That is, make is assuming that the cargo utility is installed and available on the PATH, but that doesn't appear to be true on the CRAN winbuilder machine. The salso package (https://cran.r-project.org/package=salso) explicitly requires cargo to be already available, per SystemRequirements: SystemRequirements: Cargo (>= 1.42.0) for installation from sources: see file INSTALL so you probably need to do something similar. I'd also recommend downloading the 'salso' package to see how they resolve this, or contacting the 'salso' maintainer to see what steps they took to ensure their package could build on CRAN.
