Build two programs in one project in creator

[Talei]

AFAIK use .pro files to do that.
Example: create a myServClientBuild.pro somewhere (best in parent directory of serv/client folders), then place in it:

TEMPLATE      = \
              subdirs
SUBDIRS       = \
              path-to-Server \
              path-to-Client

TEMPLATE      = \
              subdirs
SUBDIRS       = \
              path-to-Server \
              path-to-Client

To copy to clipboard, switch view to plain text mode 

Open this pro in QtCreator and work with n projects, although it sometimes gets messed up, i.e. when You want to add to the second project on the list one file it add it to the first project on the list. Same goes for UI. (But maybe it's fixed on 2.x, I use 1.3.x).
