Can't find Zend directory in EasyPHP folder

I'm about reading a tutorial about creating php extensions in C. I'm using Visual Studio 2008 and EasyPHP whose directory includes /ext folder (PHP extensions directory)

this is the tutorial : http://www.devarticles.com/c/a/Cplusplus/Developing-Custom-PHP-Extensions-Part-1/2/

I've a problem in the step 4 :

Blockquote 4. In the Preprocessor Category, add the following "Addi开发者_C百科tional include directories": ...., ....\main, ....\Zend, ....\TSRM, ....\bindlib_w32.

I searched the main , zend , tsrm and bindlib_w32 directories in the easyphp forlder and I couldn't find them.

if EasyPHP doesnot include zend directory. How can I deploy it in its correct directory?

and thank you in advance

Okey I've found the solution to my question, I was indeed looking for the zend folder in the directory of php. But I must look in the PHP code source directory, not in the php itself. thank you
