# This target unpacks the source code in the build directory.
# If the source archive is not .tar.gz or .tar.bz2, then you will need
# to change the commands here.  Patches to the source code are also
# applied in this target as required.
#
# This target also configures the build within the build directory.
# Flags such as LDFLAGS and CPPFLAGS should be passed into configure
# and NOT $(MAKE) below.  Passing it to configure causes configure to
# correctly BUILD the Makefile with the right paths, where passing it
# to Make causes it to override the default search paths of the compiler.
#
# If the compilation of the package requires other packages to be staged
# first, then do that first (e.g. "$(MAKE) <bar>-stage <baz>-stage").
