<h3 class="section">Pattern-specific Variable Values</h3>

   <p>In addition to target-specific variable values (see <a href="Target-specific.html#Target-specific">Target-specific Variable Values</a>), GNU <code>make</code> supports
pattern-specific variable values.  In this form, a variable is defined
for any target that matches the pattern specified.  Variables defined in
this way are searched after any target-specific variables defined
explicitly for that target, and before target-specific variables defined
for the parent target.

   <p>Set a pattern-specific variable value like this:

<pre class="example">     <var>pattern</var> ... : <var>variable-assignment</var>
     </pre>

<p>or like this:

<pre class="example">     <var>pattern</var> ... : override <var>variable-assignment</var>
     </pre>

<p>where <var>pattern</var> is a %-pattern.  As with target-specific variable
values, multiple <var>pattern</var> values create a pattern-specific variable
value for each pattern individually.  The <var>variable-assignment</var> can
be any valid form of assignment.  Any command-line variable setting will
take precedence, unless <code>override</code> is specified.

   <p>For example:

<pre class="example">     %.o : CFLAGS = -O
     </pre>

<p>will assign <code>CFLAGS</code> the value of <code>-O</code> for all targets
matching the pattern <code>%.o</code>.
