This macro will check for the existence of id3lib (http://id3lib.sourceforge.net/). It does this by checking for the header file id3.h and the id3 library object file. A –with-id3lib option is supported as well. The following output variables are set with AC_SUBST:
ID3_CPPFLAGS ID3_LDFLAGS ID3_LIBS
You can use them like this in Makefile.am:
AM_CPPFLAGS = $(ID3_CPPFLAGS) AM_LDFLAGS = $(ID3_LDFLAGS) program_LDADD = $(ID3_LIBS)
Additionally, the C preprocessor symbol HAVE_ID3LIB will be defined with AC_DEFINE if id3lib is available.
