Makefile

### Top-level Makefile for ld-decode ###

# Prefix into which ld-decode will be installed.
# This must be set both at build and install time. If you're using a
# non-default directory here, make sure that Python knows to look in there for
# modules (e.g. by setting PYTHONPATH in your environment).
prefix ?= /usr/local

# Staging dir for building distribution packages.
# If you're building packages, it may make more sense to build the Python and
# Qt parts using your distribution's tools, rather than using this Makefile
# (but don't forget the helpers!).
DESTDIR =

# Tools you might want to override
PYTHON3 ?= python3
