Hi tao,
In Project window go to Targets tab and mark default target

go to menu-Project-Create Target

enter new target name and select Empty target or Clone existing target (recommended)

double click on new target name (Alt+F7) will open target settings and you could change for example debugger ini file

or compiler settings

Note: Targets are selected by clicking on
icon on left side.
I hope it helps you.
Have a great day,
RadekS
