title: How to escape parenthesis for the cp command inside a Makefile
body: <p>I have this Makefile: </p>
  
  <pre><code>VAR=foo(1).txt foo(2).txt
  foobar: $VAR
      cp -p $^ foo/    
  </code></pre>
  
  <p>When I run it I get this error:</p>
  
  <pre><code>$ make test
  /bin/sh: -c: line 0: syntax error near unexpected token `('
  /bin/sh: -c: line 0: `cp -p foo(1).txt foo(2).txt foo/'
  Makefile:3: recipe for target 'foobar' failed
  make: *** [test] Error 1
  </code></pre>
  
  <p>How to quickly get rid of it?</p>
