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