Agustin,

Thanks very much! This gives a place-holder - how should we "handshake" to 
OSGeo on this? Adding this mailing list to the wiki is unhelpful for 
non-subscribers - it would be helpful to identify people to contact.

Best wishes,

Roger

Following the OSGeo shared building services initiative may help those installing from source on Windows and macOS. If we in addition can promote the provision of reliable static-linkable components, we could perhaps reduce the burden on CRAN, especially if CI could check CRAN compatability of build trains (compiler versions etc.).

CRAN packages for macOS are also static linked to custom built binaries, again using the build train used by R. Static linkage is used to avoid having to deploy a package manager for external software on which R packages depend, since CRAN as a package manager already supports over 15000 packages with three binary versions (devel, release, old release) for Windows and macOS.
