AC_LANG_C
dnl Checks for programs.
AC_PROG_AWK
AC_PROG_CC
dnl Check for headers
AC_CHECK_HEADERS(unistd.h)
dnl Checks for typedefs, structures, and compiler characteristics.
AC_TYPE_SIZE_T
dnl Detect OS we're building on
dnl this next line is required to be able to read the host value
AC_CANONICAL_HOST
dnl Use the value here to add support for other operating systems
echo "Host Value: '${host}'"

Here we specify we have files in the source directory to process
AUTOMAKE_OPTIONS = foreign
SUBDIRS = src
src/ Makefile.am
Here we define there are 2 programs we're compiling
bin_PROGRAMS = midiio midiout
and here we define what we put together to make the final programs
midiout_SOURCES = midiout.cpp RtMidi.cpp
midiio_SOURCES = midiio.cpp RtMidi.cpp
