Is it possible to get flex in the win-builder windows environment? It's present
in the debian environment. My package depends on cmake, bison, and flex. Each
of these are listed in the `SystemRequirments` field of my DESCRIPTION file but
flex is the only one that cmake can't find.
Please see CRAN repository policy and contacts included there:
https://cran.r-project.org/web/packages/external_libs.html
But if possible I would include the generated parsers in the source code
of your package. This is also how R itself does it.
The win-builder home page (https://win-builder.r-project.org/) doesn't say much
about foreign dependencies other than we have what's available in Rtools plus a
small list of others. But neither cmake or bison are available by default in
Rtools, they both have to be explicitly installed with `pacman`. Flex can also
be installed via `pacman`, so why are the other two available?
cmake is part of Rtools, please see
