+dnl @synopsis CHECK_HPDF()
+dnl
+dnl This macro searches for an installed libhpdf (libharu) library. If nothing
+dnl was specified when calling configure, it first searches in /usr/local
+dnl and then in /usr. If the --with-hpdf=DIR is specified, it will try
+dnl to find it in DIR/include and DIR/lib.
+dnl
+dnl It defines the symbol PLD_pdf if the library is found.
