A simple project file may use straightforward declarations, defining standard variables to indicate the source and header files that are used in a project. Complex projects may use multiple flow structures to optimize the build process. A project file contains a series of declarations to specify resources, such as links to the source and header files, libraries required by a project, custom-build processes for different platforms, and so on.

A Qt project file has several sections and uses certain predefined qmake variables. Let's have a look here at our earlier HelloWorld example .pro file:
