Generated R package is not valid.

[srvanderplas]

I compiled the project as instructed and the generated R package does not install using either

setwd("SimpleElastix/Wrapping/R/Packaging/SimpleITK")
devtools::install(".")
> setwd("SimpleElastix/Wrapping/R/Packaging/SimpleITK/")
> devtools::install()
Error: Could not find package root. Is your working directory inside a package?

or by compressing the package and then using install.packages() with a link to the tar.gz file.

> install.packages("~/Projects/CSAFE/2022-simpleElastix-test/SimpleElastix/Wrapping/R/Packaging/SimpleITK.tar.gz", repos = NULL, type = "source")
