qpdf/Makefile

# This makefile is inspired by abuild (http://www.abuild.org), which
# was used during the development of qpdf.  The goal here is to have a
# non-recursive build with all the proper dependencies so we can start
# the build from anywhere and get the right stuff.  Each directory has
# a build.mk that is included from here and is written from this
# directory's perspective.  Each directory also has a proxy Makefile
# that allows you to start the build from any directory and get
# reasonable semantics for the all, check, and clean targets.

# Our "build items" are directories.  They are listed here such that
# no item precedes any item it depends on.  Therefore, each item can
# safely reference variables set in its predecessors.

# For each build item B, you can run make build_B, make check_B, or
# make clean_B to build, test, or clean B.  Full dependencies are
# represented across all the items, so it is possible to start
# anywhere.  From the top level, the "all", "check", and "clean"
# targets build, test, or clean everything.

# Although this is not a GNU package and does not use automake, you
# can still run make clean to remove everything that is compiled, make
# distclean to remove everything that is generated by the end user,
# and make maintainer-clean to remove everything that is generated
# including things distributed with the source distribution.  You can
# pass CLEAN=1 to prevent this Makefile from complaining if
# ./configure has not been run.

# The install target works as usual and obeys --prefix and so forth
# passed to ./configure.  You can also pass DESTDIR=/dir to make
# install to install in a separate location.  This is useful for
# packagers.
