What is the CodeBlocks build mode for 4.18.3?

Hi guys!

I recently decided to start working on a Linux build of my game.

All has gone well so far on getting things moving on Linux. Got the engine compiled and working, set up CodeBlocks and have my game project on it.

The one and only question I have is, is there a preferred buld mode?

In Windows on Visual Studio I use Win64 Development. What is the equivalent of that in CodeBlocks on Ubuntu?

Sorry if that is a dumb question but I do not see it in the list.

Thank you in advance!
