May I suggest that having 3 files might be moving in the right direction.
Do you think the fewer the better?

Think about C++ classes and files. If you have 3 classes like A, B and C,
it is common practice
to have them defined in 3 header files in particular if they are complex
classes, even if both B and C inherits from A.
And hardly anyone would try to put the 3 of them in a single header file,
even though C++ completely support having an
arbitrary number of classes in a single file.

Even if it fits your needs, by using qmake in a non standard way you are
likely to run into troubles when
you will want to use qmake related tools like Qt Creator. Also you are
likely to increase the time a developer will need to
comprehend your project and its build mechanism. I do not think any Qt
developer is expecting a single .pro to build both
a shared library and an executable.

If you do all this just to accommodate your taste in file count, please
consider changing your taste and using qmake in a standard way.
