# GOAL
# what I want to do: given a derivation, i want to go through all of its dependencies 
# and add a cmake flag to them within an overlay. I will append these overlays to a list
# and then combine them all into one overlay to apply.

# REALITY
# right now what this can do is given a list of deps within a derivation you can make them have the compile command
