You have to do two things:

In the .pri file, do this:

SOURCES += \
   $$PWD/file.cpp ...

Always use the $$PWD in included pri files from other directories

Usually, I place the directories as subdirs of the one that hold the 
.pro file(s) because then I can use #include "subdir/file.h". If you 
prefer, you can add the subdirs to the include path by adding

INCLUDEPATH += $$PWD

in the .pri file.

One final thing: You *can not* have two files with the same names in 
different directories when you are using pri files as subprojects 
because the generated .o files are all placed in the same directory.
