build hooks

{
  buildInputs = [ cmake ];
}

autoreconfHook - run autreconf on broken autotools
autoPatchelfHook - automatically fixup binaries, good for pre-built dist
breakPointHook - add a breakpoint to failing builds
makeWrapper - add wrapProgram utility
pkg-config hooks

search for make

packaging a C program

all-packages.nix
callPackage

entering the build

cntr support

breakpointHook

  src = fetchFromGitHub { ... };  # Incomplete
  goDeps = ./deps.nix;
