Dear list,
I've been working on an image processing package for R
(https://github.com/dahtah/imager) that uses Rcpp to provide an
interface to the CImg library.
Cimg is contained in just one header file, which makes it easy to ship
with an R package. It is relatively self-contained, but some
functionality requires external dependencies, such as libpng, libjpeg,
libfftw3 and opencv. These additional modules can be included at compile
time via a #define statement, but of course the right headers and
libraries need to be present.
I'm trying to find a way to provide the additional functionality without
forcing the user to install these dependencies. On Linux/Mac a possible
way to do that would be to use autoconf, but from what I read Windows
support is going to be headache. Does anyone have advice on
alternatives? Much appreciated.
Best
Simon Barthelme
