A YAML parser for Fortran: fortran-yaml-cpp

I think there are three ways:

  • You can just call cmake to build the C++ package in a build script that fpm just calls
  • You can assume it is already installed, so you just tell fpm the correct compiler flags to link with it
  • You provide an fpm build system for the C++ package and just depend on it

@awvwgk, what is the best way forward in this case?
