It wont be *one* click, but close.
Go into the "Project Options" => Compiler Options
Select "Build modes"
There is a button "create debug and release" modes. [1]
You can also do that, and set it as default for all new projects.
In the IDE main bar, there is an icon to select the build mode, so you can quickly toggle, and then build.
-------------------------------
[1] AFAIK that only affects project, but not packages. So LCL still has dbg info.
But you can edit the build mode once, and add "strip", or use "additions and overrides" to change packages....
