# Generic configurable recipes to build packages with GNU Build system or
# CMake. This is Makefile is not intended to be run directly, it will be
# imported into `basic.mk' and `high-level.mk'. They should be activated
# with Make's `Call' function.

# IMPORTANT note
# --------------
#
# Without using `&&', if a step fails, the process will continue. However,
# in the `if' statements, we need `;' (particularly between `]' and
# `then'). So we need to put any necessary checks at the start, then when
# we start the process, every command will be separated by an `&&'.
# GNU Build system
# ----------------
#
# Arguments:
# 1: Directory name after unpacking.
# 2: Set to `static' for a static build.
# 3: Extra configuration options.
# 4: Extra options/arguments to pass to Make.
# 5: Step to run between `make' and `make install': usually `make check'.
# 6: The configuration script (`configure' by default).
# 7: Arguments for `make install'.
#
# NOTE: Unfortunately the configure script of `zlib' doesn't recognize
# `SHELL'. So we'll have to remove it from the call to the configure
# script.
#
# NOTE: A program might not contain any configure script. In this case,
# we'll just pass a non-relevant function like `pwd'. So SED should be used
# to modify `confscript' or to set `configop'.
