dnl @synopsis AC_ma_SEARCH_PACKAGE(PACKAGE, FUNCTION, PREFIX LIST, LIBRARY LIST, HEADERFILE [, ACTION-IF-FOUND [, ACTION-IF-NOT-FOUND]])
dnl based on AC_caolan_SEARCH_PACKAGE
dnl
dnl Provides --with-PACKAGE, --with-PACKAGE-include and --with-PACKAGE-libdir
dnl options to configure. Supports the now standard --with-PACKAGE=DIR
dnl approach where the package's include dir and lib dir are underneath DIR,
dnl but also allows the include and lib directories to be specified seperately
dnl
dnl PREFIX LIST can be a list of directories to search for the package
dnl if set to "no", the package must be enabled with --with-PACKAGE
dnl otherwise it is enabled unless overridden with --without-PACKAGE
dnl
dnl adds the extra -Ipath to CFLAGS if needed
dnl adds extra -Lpath to LD_FLAGS if needed
dnl searches for the FUNCTION in each of the LIBRARY LIST with
dnl AC_SEARCH_LIBRARY and thus adds the lib to LIBS
dnl
dnl defines HAVE_PKG_PACKAGE if it is found, (where PACKAGE in the
dnl HAVE_PKG_PACKAGE is replaced with the actual first parameter passed)
dnl note that autoheader will complain of not having the HAVE_PKG_PACKAGE and you
dnl will have to add it to acconfig.h manually
