# You must replace "alsa-lib" and "ALSA-LIB" with the lower case name and
# upper case name of your new package.  Some places below will say
# "Do not change this" - that does not include this global change,
# which must always be done to ensure we have unique names.

#
# ALSA-LIB_VERSION, ALSA-LIB_SITE and ALSA-LIB_SOURCE define
# the upstream location of the source code for the package.
# ALSA-LIB_DIR is the directory which is created when the source
# archive is unpacked.
# ALSA-LIB_UNZIP is the command used to unzip the source.
# It is usually "zcat" (for .gz) or "bzcat" (for .bz2)
#
# You should change all these variables to suit your package.

# ALSA-LIB_BUILD_DIR is the directory in which the build is done.
# ALSA-LIB_SOURCE_DIR is the directory which holds all the

# ALSA-LIB_IPK_DIR is the directory in which the ipk is built.
# ALSA-LIB_IPK is the name of the resulting ipk files.

#
# 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").
