When you open crowbar, the top section has tabs like decompile and compile, on the far left of those tabs are the set up games tab. You want to select the game you want to compile for in the gray bar when you open that tab.

The Game setup section just asks you to browse your selected game's folders and select specific files like HLMV and StudioMDL you can usually just find these in the Bin folder of any source game.
