Another way to manage dependencies?

[dilawar]

Currently Smoldyn has most dependencies in the source and everything works fine. There is merit in keeping dependencies in source tree.

Another approach would be to manage dependencies using a dependency manager. C++ doesnt have a standard package manager but there are two major options: conan and vcpkg. I have used conan in the past and it works great.

Except for freeglut, all dependencies are available via conan (for all supported platforms). conan can be integrated into cmake itself.

This will make source distribution lighter and testing easier. On the flip side, the users would need a working internet connections to download the dependencies.

Thanks for this suggestion. I think I'd rather keep things as they are for now, but it's good to know about this for the future. At the moment, I'm not concerned about the distribution size, but I am eager to keep Smoldyn as a single self-contained package if at all possible.

https://github.com/dilawar/Smoldyn/tree/conan has the conan based dependency management. I manage to remove boost, eigen, tiff and pybind11 from the source tree. It is on very low priority. It might be helpful in the future for building Smoldyn on ARM, RISC-V and other popular platforms.

Thank you! I don't have time to look into it now, but will do so when I get a chance. -Steve

CMake now has a FetchContent module https://cmake.org/cmake/help/v3.15/module/FetchContent.html that can be used to download/build all the dependencies (except boost).
