Does it work in normal build?

DbgDraw works in a build only, if you tick the Development Build checkbox in the Build Settings window (File > Build Settings).

Can I somehow make it work without this checkbox?

I wrote the code that it only works in development builds on purpose. If you want to use it in non-development builds, you would need to change the code.
