We really want to get rid of having compiled code imported during the
installation process. Ideally talk to Tomas Kalibera to get the
libraries you need included in to the next Rtools update.

Hi r-package-devel
I am working on updating my package `sundialr` (
https://cran.r-project.org/web/packages/sundialr/index.html), wherein I was
earlier bundling the C source files with the package, but now I am using
`cmake` to create static libraries for the upstream C library SUNDIALS
which the package provides an interface for. In brief, the previous
approach can be found at:
https://github.com/sn248/sundialr/blob/master/src/Makevars
And the new approach can be seen below (heavily borrowed from nloptr
package installation approach):
https://github.com/sn248/sundialr/blob/cmake-install/tools/cmake_call.sh
The second approach works successfully on linux and macOS platforms
(checked by rhub).
I am struggling to get this working on a Windows platform, and have looked
at a few packages (e.g., nloptr, rcppredis, openssl) which have solved this
issue. As I understand the following steps are required to get the static
libraries in correct locations for package installation on the Windows
1) Host the .tar.gz files or .zip files on https://github.com/rwinlib/
(deprecated now) or https://github.com/r-windows/bundles/releases/download/
which should contain the static libraries (*.a files) in separate folders
for i386, x64-ucrt and x-64 platforms and required header files in the
`include` folder.
2) Use a winlibs.R file within the `tools` sub-directory in the package
file structure to download the .zip or .tar.gz file and extract them to a
`windows` directory.
3) Set PKG_CPPFLAGS and PKG_LIBS via Makewars.win file in src sub-directory
in the package files.
Currently, I am struggling with Step #1, i.e., how to create the required
.zip or .tar.gz files and host them on
https://github.com/r-windows/bundles/releases for download. I will be
thankful if any one can provide some guidance in this regard.
Sincerely
Satya
