Compiling cpp files with qt cmd

[Noks]

Hello all,
I am having some errors with my use of qmake command.this is what i did:
1.created a cpp file.
2.in qt cmd i wrote qmake -project hello.cpp;this created project file
3.then in the cmd i wrote qmake,this created the make files and debug files..etc
BUt the problem is there is no executable file in any folder say neither in debug or release.so how do i get the executable file..i am comfortable with the ide but how to use the cmd....
