An additional option is to go to your build folder and use the command ccmake    This is like the GUI but terminal based  This obviously won t help with an installation script but at least it can be run without a UI   The one warning I have is it won t let you generate sometimes when you have warnings  if that is the case  exit the interface and call cmake

Delete the CMakeCache txt file and try this   cmake -G  1 -DBUILD SHARED LIBS ON -DBUILD STATIC LIBS ON -DBUILD TESTS ON      You have to enter all your command-line definitions before including the path
