1dnl @synopsis AC_CHECK_PACKAGE(PACKAGE, FUNCTION, LIBRARY , HEADERFILE [, ACTION-IF-FOUND [, ACTION-IF-NOT-FOUND]])
2dnl
3dnl Provides --with-PACKAGE, --with-PACKAGE-include and --with-PACKAGE-libdir
4dnl options to configure. Supports the now standard --with-PACKAGE=DIR
5dnl approach where the package's include dir and lib dir are underneath DIR,
6dnl but also allows the include and lib directories to be specified seperately
7dnl
8dnl adds the extra -Ipath to CFLAGS if needed
9dnl adds extra -Lpath to LD_FLAGS if needed
10dnl searches for the FUNCTION in the LIBRARY with
11dnl AC_CHECK_LIBRARY and thus adds the lib to LIBS
12dnl
13dnl defines HAVE_PKG_PACKAGE if it is found, (where PACKAGE in the
14dnl HAVE_PKG_PACKAGE is replaced with the actual first parameter passed)
15dnl note that autoheader will complain of not having the HAVE_PKG_PACKAGE and you
16dnl will have to add it to acconfig.h manually
