### Notes ###
#### Notes ####################################################################
# This build process is done in three stages:
# 1. copy source files to the local build directory.
# 2. replace the string "$INSTALL_PREFIX" with the value of $PREFIX
# 3. copy files from the build directory to the target directory.
#
# Why this dance?
# * To fully support that a user can install this project to a custom path e.g. $(PREFIX=/usr/local make install),
# we need to modify the files that refer to other files on disk. We do this by having a placeholder "$INSTALL_PREFIX"
# that is substituted with the value of $PREFIX when installed
# * We don't want to modify the files that are controlled by git, thus let's copy them to a build directory and then modify.
