Active projects- how to choose project to build

[Tigers!]

Have just started with Codelite and got the ubiquitous 'Hello world' to work.
I have created a new workspace in the right hand frame and typed in my code. When I use F7 it builds the former project ('Hello world') not my new one. I notice that in the Workspace view frame I can see the old project (Mobius_errors) and the new project (AU_PICKLIST) in the tree. The Mobius_errors is enbolded and I assume that it means that this project is the active one rather than the one in the work space. Is this correct? If so how do I highlight and build my new project? Codelite must have done some form of compiling as my new project (AU_PICKLIST) has main.o and and a main.o.d files under a debug folder that Codelite presumably created. Codelite appears to be using g++
----------Build Started--------
"mingw32-make.exe" -j 2 -f "SEW-Eurodrive_wsp.mk"
----------Building project:[ Mobius_errors - Debug ]----------
g++ -o ./Debug/Mobius_errors ./Debug/main.o
----------Build Ended----------
0 errors, 0 warnings
(Note that is the build message from the original project rather than the one I wisd to build)
Where will Codelite store all the resultant files? At present I need to go searching for the various files. Can we change paths/settings etc?

Also can we call the xx.cpp files any name we like e.g. myfile.cpp?

Right click on the project name and select 'Set as active'

OR

On top of the project view, there is a small toolbar (5 icons) hover them and u will get a tooltip, one of them says 'set active project'
