eclipse cdt relative include path?

Привет всем. Я скачал и переместил источник Xerces (v3.1.1) здесь: / usr / include / xerces, и я могу видеть источник в проводнике проекта следующим образом:

MyCppProject

• Двоичные файлы

• Включает

  • [...] // некоторые другие каталоги

  • xerces

    • dom

    • [...] // some other directories

And, here's my simple C++ code:

#include <xercesc/util/PlatformUtils.hpp>

using namespace xercesc;
#include <iostream> 
using namespace std;
int main(int argc, char* argv[])
{
  try {
      XMLPlatformUtils::Initialize();
  }
  catch (const XMLException& toCatch) {
      return 1;
  }
  XMLPlatformUtils::Terminate();
  return 0;
}

And, here's the error that I get (along with others that are caused by this file not being included):

../main.cpp:1:42: error: xercesc/util/PlatformUtils.hpp: No such file or directory

What I don't understand is how the relative paths work in the source file. When I say type

#include <xercesc/util/PlatformUtils.hpp>

where is it looking, if not on the include paths already listed in the project explorer?
