Synopsis

<p class="indent" style="white-space:nowrap;">
<code>IMMDX_LIB_METIS([ACTION-IF-FOUND], [ACTION-IF-NOT-FOUND])</code>
</p>
<h2>
Description
</h2>
<div class="indent">
<p>
This macro searches for the METIS library in the user specified location.
The user may specify the location either by defining the environment
variable METIS or by using the --with-metis option to configure. If the
environment variable is defined it has precedent over everything else. If
no location was specified then it searches in /usr/lib and /usr/local/lib
for the library and in /usr/include and /usr/local/include for the header
files. Upon sucessful completion the variables METIS_LIB and METIS_INCLUDE
are set.
</p>
<p>
ACTION-IF-FOUND is a list of shell commands to run if a METIS library is
found, and ACTION-IF-NOT-FOUND is a list of commands to run it if it is not
found. If ACTION-IF-FOUND is not specified, the default action will define
HAVE_METIS. If ACTION-IF-NOT-FOUND is not specified then an error will be
generated halting configure.
