title: How to make created packages available on make menuconfig?
body: <p>I'm trying to create a libxerces package for OpenWrt. Following the instructions from this site <a href="http://wiki.openwrt.org/doc/devel/packages" rel="nofollow">http://wiki.openwrt.org/doc/devel/packages</a>, I created a folder called libxerces-c inside the packages directory and a simple Makefile to have the package listed on make menuconfig, but it's not happening.</p>
  
  <p>The Makefile is defined as the following:</p>

  define Package/libxerces/description
    Xerces-C++ is a validating XML parser written in a portable subset of
    C++.  Xerces-C++ makes it easy to give your application the ability
    to read and write XML data. A shared library is provided for parsing,
    generating, manipulating, and validating XML documents. Xerces-C++ is
    faithful to the XML 1.0 recommendation and associated standards (DOM
    1.0, DOM 2.0, SAX 1.0, SAX 2.0, Namespaces, XML Schema Part 1 and
    Part 2).  It also provides experimental implementations of XML 1.1
    and DOM Level 3.0.  The parser provides high performance, modularity,
    and scalability.

  <p>I already tried to execute the install script </p>
  
  <pre><code>./scripts/feeds install libxerces-c
  </code></pre>
  
  <p>But nothing happened. I still can't see the package after executing make menuconfig.</p>
