For example projects, change the generated project() call to
project(foo VERSION 1.0 LANGUAGES CXX)
Some CMake API derives default values from the project version, and it's
generally advisable to set a project version number.
The version number is read from qmake's VERSION variable. That's
actually a target version number, but it might be the right thing in
most cases. Fall back to version 1.0 if VERSION is not set.
