Is the global way ( for all projects) like this :
Setting menu / compiler... / select desired compiler /
yes but:
It is generally not a good idea to modify the global flags. A better way is to create a template project and use this, or modify the wizard script for the default project (a bit advanced)
For creating a project template:
1) Create a new project and set all settings as you like
2) Save the project as template with File->Save project as template
now if you want to use this template
File->New-> project->User templates
