You can also tell your customers to install the libXext development  
package.  Some distros automatically do that when installing the qt4  
development package, some don't.

Or you can copy the FindQt4.cmake from CMake 2.6, with maybe a few  
tweaks to make it work with CMake 2.4.  But that's an extra thing to  
maintain.
