I have read the qmake reference but I dont know how to use the INSTALLS
What does INSTALLS?
it copy files FORM target path to current build dir or TO target path ?
target.path =
target.files +=

And .. How I say to make or Qmake that does it ?
Have I to write some argument at build steps elements at Projects build settings tab ?

(I'd like to use INSTALLS to copy some files builded to a distribution folder)

I have some confused... And I dont find any useful help on the web.
Any help will be appreciated . Thanks
