# _Packaging_ instructions for libejovo

#   This file encodes the build/installation instructions scattered throughout the
# README.md into a single nix expression.

# We start off my making a simple derivation

    # Manual override of different phases:
    #
    # Note:
    #   There is a "configurePhase" that get's called by a genericBuild which -
    #   at a bare minimum - calls `cmake` to configure the project.
    #
    # Additional note:
    #
    #   The "stdenv.mkDerivation" default phases are much more robust and
    #  properly set the cmakeflags to use and include files and what not.
    #  The below instructions don't actually work that well (buildPhase works if we don't touch configurePhase though...)
