@majorheading Synopsis

@smallexample
AX_LIB_TABIX()
@end smallexample

@majorheading Description

This macro searches for an installed tabix library. If nothing was
specified when calling configure, it searches first in /usr/local and
then tries with ld's default library search path. If the
--with-tabix=DIR is specified, it will try to find it in
DIR/include/tabix/tabix.h and DIR/lib/libtabix.a. As a final try it will
look in DIR/tabix.h and DIR/libtabix.a as the tabix library does not
contain an install rule.

If --without-tabix is specified, the library is not searched at all.

If either the header file (tabix.h) or the library (libtabix) is not
found, the configuration exits on error, asking for a valid tabix
installation directory or --without-tabix.

The macro defines the symbol HAVE_TABIX if the library is found. You
should use autoheader to include a definition for this symbol in a
config.h file. Sample usage in a C/C++ source is as follows:

@smallexample
  #ifdef HAVE_TABIX
  #include <tabix.h>
  #endif /* HAVE_TABIX */
@end smallexample

The following output variables are set with AC_SUBST:

@smallexample
  TABIX_CPPFLAGS
  TABIX_LDFLAGS
  TABIX_LIBS
@end smallexample

You can use them like this in Makefile.am:

@smallexample
  AM_CPPFLAGS = $(TABIX_CPPFLAGS)
  AM_LDFLAGS = $(TABIX_LDFLAGS)
  program_LDADD = $(TABIX_LIBS)
@end smallexample
