Hi Sylvain,
Thanks for posting here (even if this is more of a CMake than a Debian question ...).

R itself uses GNU autoconf extensively (and fixed scripts on Windows). For the same reason, CMake is not that widely used for R package builds. However, given that more and more _external_ libraries use CMake, you see it used in R packages to provide these external libraries. Now, R is also not that often embedded [1] which may explain why you don't find many FindR.cmake or FindRLibs.cmake. That said, searching at GitHub (a good resource for this!!) find 285 hits for FindR.cmake: https://github.com/search?q=FindR.cmake&type=repositories 57 hist for FindRLibs.cmake: https://github.com/search?q=FindRLibs.cmake&type=code Maybe those can help you? Cheers, Dirk [1] I wrote a package for that: RInside. It's on CRAN and at my GitHub, but again no CMake apart for an older contributed examples configuration. | | Thanks! | | Sylvain | | (France) | | [[alternative HTML version deleted]] | | _______________________________________________ | R-SIG-Debian mailing list | R-SIG-Debian@r-project.org | https://stat.ethz.ch/mailman/listinfo/r-sig-debian -- dirk.eddelbuettel.com | @eddelbuettel | e...@debian.org _______________________________________________ R-SIG-Debian mailing list R-SIG-Debian@r-project.org https://stat.ethz.ch/mailman/listinfo/r-sig-debian
