The correct statement in this sentence is "bad approach". QMake is designed 
this way - suck it up or chose a different build tool!

BTW: the general direction of most of my projects is to accumulate more 
directories and more project files with all the common stuff in a central .pri 
file. Refactoring for me usually means to split up projects into independent 
libraries that can be more freely combined and more easily tested. 
Modularization isn't popular because it is a cool word, but because it works.

You are not doing yourself any service by insisting on a single directory and 
a single project file - on the contrary you are creating a trap that your 
future self with get sucked into. Good luck! You will need it.

For complex projects to have a separate makefile to direct the build process is 
a good idea anyway. But please keep the projects in separate files and if at 
all possible in separate directories. You will thank yourself for this later.

If you don't believe me: please go ahead and try, but plan significant time for 
refactoring a few years from now. I'm sure you'll come to the same conclusions 
that I (and most of us seniors here) did years ago.
