I took a look at one of the include files to see what is included. Qt header files are included via
angle-bracket form of
#include directive, see, for example
http://msdn.microsoft.com/en-us/library/36k2cdd4%28v=vs.80%29.aspx[

My first guess is: you need to setup compiler options to use appropriate include directories to make a compiler look up for them when angle-bracket form of include is found. Did you do it? For example, the MSDN article referenced above shows how to do it for the Microsoft C++ compiler.
