Jerry,

After you ran configure, what did configure report for the expat library "sys"
or "builtin"?  On both Linux (Debian testing) and Windows (MinGW/MSYS) I'm
using the system libraries without any issues.  I don't know that this makes
any difference but it could.  Also, it may be the version of wxWidgets you are
using.  I had to update from 2.8.10 to 2.8.11 because
wxXmlNode::GetAttributes() does not exist prior to 2.8.11.  This may also apply
between the 2.9.0 and the 2.9.1 branch.  You can verify this by grepping
<wx/xml/xml.h> for GetAttributes.

I've been toying with the idea of adding a version check to FindwxWidgets so
CMake will choke if the correct version of wxWidgets is not available (ala
autoconf) rather than having to figure that out after a build failure.  Library
version checking is one of the places most of the CMake find modules are a bit
weak.  If no one objects to this idea, I'll add it to my todo list and try to
knock it out in the not too distant future.

Note to all developers: the current minimum version of wxWidgets to build the
testing branch of Kicad is 2.8.11.
