IIUC, you can set additional flags in your stack.yaml file:
flags:
ncurses:
flagname: true # or false

Hi everyone, I'll try with tl:dr; first: I have a project with a dependency that -on my system- needs a build flag, in order to correctly link against its native dependencies. What is a proper way to set up a project like this?
A longer explanation: My project uses `ncurses` library and I'm running Arch. There seems to be some religious opinion going around about the layout of ncurses headers in /usr/include, and -naturally- Arch and `ncurses` disagree. Fortunately, author of `ncurses` included a build flag to allow (easy) build on systems which follow the 'wrong' layout.
Thing is, I couldn't figure out how to add this configuration to the .cabal of my own project, so for now, I'm stuck with a Makefile that invokes `stack` commands with `--flag ncurses:force-narrow-library`. I looked in the manual and there doesn't seem to be a way to handle this aside the commandline argument.
So this got me thinking - is there a different way projects like these are supposed to be organized? For example, am I supposed to check out `ncurses` as a submodule of my project, then replicate this build flag on my own project and 'pass it down' somehow?
Any tips are highly appreciated; I'm really not proficient with organizing stack projects properly.
Cheers!
