# This makefile uses 2 code generators:
#
#   1. gengetopt - this needs to be installed on the host.
#   2. audio-tool-build-generate-wave-table - this is built as part of
#   the project.
#
# This makefile is a little confusing because it must handle this.
# For the wave tables, all the source files are properly generated in
# the intermediates directory. However, for gengetopt, the cleanest
# solution is to generate the files in the source directory instead of
# the intermediates directory, because it avoids having to
# -I. (i.e. the android top-of-tree).
